Ryanair redefines “low cost” with a sticky tape fix

October 25, 2011

Ryanair apparently considers that the use of sticky tape to fix cracks in aircraft is a routine technical issue. It begs the question as to how often Ryanair fixes its mechanical problems on aircraft with string and sticky tape.

Ryanair flight forced to land after crew fixed pilot’s window with sticky tape 

A Ryanair flight carrying 200 people was forced to turn back to Stansted after sticky tape used to ‘patch up’ the pilot’s window came loose. 
The Irish Aviation Authority (IAA) said the tape was being used merely as an extra precaution to secure a new window seal. 
But the pilot made the decision to terminate the flight after the tape became loose and started making flapping noises. One passenger, Anthony Neal from Kent, told The Sun: ‘We were kept in the dark, and were terrified. I could see guys taping in the windscreen with what looked like duct tape or gaffer tape. ‘We were in the sky, then the pilot said due to damage on the windscreen, we were going to have to turn back.’ 
Ryanair has insisted that normal procedures had been followed and that there was no danger to passengers or crew. A spokesman said: ‘We do not comment on routine technical issues. All Ryanair flights operate in accordance with approved safety standards.’

Jaguar Land-Rover thrives under Tata and fuels Tata Motors profits

September 18, 2011

When the Tata Group with Ratan Tata acquired Jaguar Land-Rover (JLR) in 2008 there were many disturbing and even depressing omens. The financial crisis of 2008 was just beginning to emerge. JLR was bleeding cash and Ford Motor Company were happy to bail out for the $2.3 billion that the Tata Group paid. In India Tata shareholders and analysts were concerned that they had bitten off more than they could chew. The Tata Group had relatively low debt and the levels of debt that they would have to take on not only for the acquisition but almost as much again for investment in JLR raised the fears that JLR could bring not only Tata Motors but the whole group down. The price was seen as being too high for what was considered a “vanity” acquisition. In the UK there were fears that the strong Jaguar and Land-Rover brands would be hurt badly by coming under Indian ownership. Jobs would be lost to Mumbai and technology would be stolen the story went. The company culture would be destroyed and innovation would come to an end. How could an Indian company messing around with a car like the Nano have the audacity to think that they could offer anything to two thoroughbred brands such as Jaguar and Land-Rover?

But 3 years on the story of JLR under Tata is an island of optimism in a gloomy sea. And it is not just optimism. The “vanity” acquisition has a gilded edge. JLR profits are up sharply and it contributes more than 50% of Tata Motors profits. An Indian company that dealt primarily with cheap small cars and trucks succeeded where Ford Motor Co and few others before had failed.

The Telegraph: Jaguar Land Rover is poised to deliver a major boost to the Government’s plans to boost growth by confirming this week that it will build a £400m engine plant in the Midlands that will potentially create up to 2,000 jobs.

JLR’s fortunes have undergone a dramatic transformation under the ownership of Indian group, Tata Motors, which bought Jaguar and Land Rover from Ford in 2008. …. 

The company was forced to turn to the Government for support in 2009 when car sales around the world crashed, but walked away from negotiations when Lord Peter Mandelson, the trade secretary, demanded strict terms including the right to appoint the chairman. The company then secured debt from commercial lenders and was able to reap the benefits of a surge in demand for Jaguars and Land Rovers in Asia.

In the year to March 31, JLR made a record pre-tax profit of £1.1bn after increasing sales by 26pc to 243,621. Under the leadership of chief executive Ralf Speth and Tata chairman Ratan Tata, JLR is investing £1.5bn a year in new products and has ambitions to drive production at its three Midland plants to 500,000 vehicles a year. The company has already hired 3,000 staff this year, including a record 350 graduates, and now employs almost 21,000 people in the UK.

JLR’s engines are currently supplied by Ford from plants including Bridgend and Dagenham in the UK…… 

Mr Tata also played down the loss of Carl-Peter Forster, who has stepped down as Tata Motors chief executive. He said: “The credit for the turnaround of Jaguar Land Rover goes to the management team and workforce. No single person can or should take credit.”

And the culture-clash that was feared just did not happen. Instead a new spirit seemed to be infused into JLR. Kevin Stride, the chief engineer of the highly-acclaimed XF program said in 2009

“There’s a real buzz around the brand at the moment, Even in a difficult world, there’s a buzz because we’re feeling empowered, we’ve got the right product line-up to go and tackle the world and we’re gaining some confidence. 
“If you went to people at different function levels in Jaguar Land Rover and asked what they thought of Tata, you’d get a big thumbs-up. It’s a good place to be at the moment. For individuals like myself, it’s changed for the better. We had a great relationship under Ford. People were cynical about that, but they were a very good company to work for. With Tata, it’s different, but different in a good way. …. We are held accountable very clearly as an independent company, whether in engineering or marketing or finance, we are held accountable for proper business performance, which in the old regime was a little filtered. It was very difficult to see cause and effect. We were not able to be as focused as we are now. ….. Tata has a very healthy way of approaching all the businesses they own. They don’t centralise it, they don’t put layers of bureaucracy in it. They evaluate the business model; if they like it, they buy the company and demand that they deliver on the business plan. You can’t just meander off and fail. ……. Cultural change is the hardest thing to do. It does take time. But we’ve been with Tata for a year, we are more agile already, people (within JLR) are questioning why we do things and if it adds value, and we are feeling more empowered to go and attack it. If it doesn’t make any sense and it adds another layer, let’s not do it any more.

…. Since Tata have come in, we’ve now got an insight into how they deal with Indian sources and sources within the whole of South-East Asia. My perception is that they are extremely focused businessmen and extremely principled in what they do, which is great coaching for us as a company. We’ve gone and looked at how they operate as a company – how they source components, how they design them, how they manufacture them – and we’ve got quite a bit to learn from them on the business side.

Jaguar is able to offer an insight into quality processes in the premium world. In terms of our engineering simulation and development, we’re pretty advanced for a company the size of Jaguar Land Rover. That’s something we’ll be able to provide benefit to the Tata Group in years to come”.

And the story is far from over yet. While cash management is the mantra of the moment, there are ambitious plans for the introduction of new models and upgrades of the existing ones in a long-term plan that runs until 2014. Tata Motors and JLR are now in “very intensive discussions” with a leading Chinese car maker about forming a historic joint venture that would see the company also produce its luxury cars in China.

CarAdvice: With tough economic times hurting sales of Tato’s famous Nano, Jaguar Land Rover are now generating a massive 57 percent of Tata’s revenue. The British brands have seen their pretax profit increase 20-fold to 1.12 billion pounds ($1.76 billion) for the fiscal year. As it stands today, Tata and its Jaguar Land Rover division is valued at over $12 billion.

It wasn’t just a matter of good fortune that the brands have become successful, in fact, Jaguar is still striving to improve with sales down 27 percent for the last quarter. Land Rover on the other hand, has seen significant growth (up 22 percent for last quarter) following strong demand for its upmarket SUVs.

The Range Rover Evoque  has already seen more than 20,000 pre-orders, despite not going on sale till September.

Tata is investing a massive $2.5 billion into Jaguar Land Rover product development each year to keep the flow of new products coming. This should see Jaguar offer a significantly larger range to turn the sales slide around. The multi-billion dollar annual investment will see the development or upgrade of 40 new vehicles across the two brands over the next five years. The two that we look forward to the most are the Jaguar C-X75 supercar and an entry-level sedan to rival the Mercedes-Benz C-Class and BMW 3 Series.

The C-X75 is meant to showcase Jaguar’s engineering prowess and build its brand credibility to compete with its German rivals. The hybrid supercar can accelerate from 0-100km/h in under three seconds and run on electric power alone for around 50km: image CarAdvice.com.au

It will be tough for Jaguar to mount a serious challenge to Audi, BMW and Mercedes-Benz but perhaps with Tata Motors this is not impossible. And it will be a healthy and welcome development for the car industry.

Misuse of peer review by UK Research Councils leads to mediocrity

September 14, 2011

The 7 UK Research Councils are publicly-funded agencies responsible for the funding of most research in the UK. They have often been criticised for being much too “establishment” driven such that any line of research considered heretical is strangled of any funding. Donald W. Braben is honorary professor in the department of earth sciences, University College London and known for his support for academic freedom and “blue-skies” research. In an article in The Times Higher Education Supplement,  he comes down hard against the research councils and their use of “peer review”. He argues that they inherently discourage  any “pioneering” research and drive towards mediocrity.

Until about 1970, academic researchers were usually given modest funds to use as they pleased. This apparent profligacy led to a prodigious harvest of unpredicted discoveries and huge stimulants to economic growth. ……. 

It is said that peer review is like democracy: it’s not the best but it’s the best we know. But science is not democratic. One doubtful scientist can be right while 100 convinced colleagues can be wrong. Indeed, the physicist Richard Feynman once defined science as “the belief in the ignorance of experts”. Specifically, peer review of grant applications, or peer “preview”, is inimical to radically new ideas. Today, however, the all-powerful peer-preview bureaucracy is the determinant of excellence. It is taboo even to criticise it. So the natural inclination to oppose major challenges to the status quo has become institutionalised. For radical research, one can argue that “the best we know” has become the worst. 

“Independent expert peer review” is contradictory. One submits a proposal and the councils ask experts to assess it. But these experts are likely to include proposers’ closest competitors, even if they are selected internationally, because science is global – and real pioneers have no peers, of course. How then can the councils ensure that reviews are independent? To make matters worse, these experts can pass judgement anonymously: applicants don’t know who put the boot in.

I suggest that the misuse of peer review is at the heart of the research councils’ problems. Before about 1970, they largely restricted its use to the assessment of applications for large grants or expensive equipment. Scientific leaders protected the seed corn, ensuring that young scientists could launch radical challenges if they were sufficiently inspired, dedicated and determined. Today, the experts whose ignorance they would challenge might also influence their chances of funding. ………

….. The research councils are taking UK research down pathways to mediocrity and using peer review as justification. We – the academic community – must stop them, or accept the dire consequences.

First private space flight to the ISS in November?

August 16, 2011

California-based rocket maker SpaceX said that it will make a test flight in late November to the International Space Station, now that NASA has retired its space shuttle program.The Dragon space capsule to be launched by a Falcon Heavy rocket has been given a November 30th launch date by NASA.

The Space X news release is here.

“SpaceX has been hard at work preparing for our next flight — a mission designed to demonstrate that a privately-developed space transportation system can deliver cargo to and from the International Space Station (ISS),” the company, also called Space Exploration Technologies, said in a statement.

The mission is the second to be carried out by SpaceX, one of a handful of firms competing to make a spaceship to replace the now-defunct US shuttle, which had been used to carry supplies and equipment to the orbiting outpost.

“NASA has given us a November 30, 2011 launch date, which should be followed nine days later by Dragon berthing at the ISS,” the company said.

It said the arrival of the vessel at the space station would herald “the beginning of a new era in space travel.”

“Together, government and the private sector can simultaneously increase the reliability, safety and frequency of space travel, while greatly reducing the costs,” SpaceX said.

The company won $75 million in new seed money earlier this year, after it became the first to successfully send its own space capsule, the gumdrop-shaped Dragon, into orbit and back in December 2010.

3-D printing!! Cool

July 16, 2011

A 3-D printer.

Very cool!!

http://www.youtube.com/watch?

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.

The difference between a scientist and an engineer

July 15, 2011

I like this practical  (rather than philosophic) formulation:

A scientist observes and describes what is but which has not been observed before, or causal relationships between existing or new observations or – when necessary – creates the language to make such descriptions possible.

An engineer uses what is together with known causal relationships to create artefacts.

Where such artefacts are created for the first time he is also an inventor.

Rolls Royce settles with Qantas for over $100 million

June 22, 2011

Qantas has reached a settlement with engine maker Rolls-Royce over last year’s mid-air disintegration of a the Trent 900 engine, which temporarily forced the grounding of its entire fleet of A380s. The terms of the agreement have not been revealed but will give Qantas a $100 million (A$95 million) boost in profits. For Rolls Royce the cost of the Qantas settlement is therefore likely to be somewhat greater and my guess would be in the region of $110 million.

My estimate made in November 2010 that Rolls Royce would face a hit of around $300 million for direct costs and in settlement costs seems to be not far off the mark. The cost to Rolls Royce of loss of future sales remains intangible and perhaps only temporary.

The Telegraph:

Alan Joyce, the Qantas chief executive, said the terms of the agreement are confidential, but said the settlement’s profit and loss impact would amount to a A$95m boost to the Australian airline’s bottom line.

Mr Joyce said the settlement marks an end to the legal proceedings Qantas launched against Rolls-Royce in the Federal Court of Australia in December.

In November, a Rolls-Royce Trent 900 engine on a Qantas A380 disintegrated shortly after takeoff from Singapore, forcing the plane to make an emergency landing.

The Australian Transport Safety Bureau’s interim report on the A380 incident said a manufacturing defect in an oil pipe deep within one of the engines led to an oil leak, which sparked a fire. The fire caused a disintegration of one of the engine’s giant turbine discs, sending pieces of it shooting through the plane’s wing and raining onto the ground below.

The engine explosion was the most significant safety issue an A380 had ever faced since it began passenger flights in 2007, and prompted intense scrutiny of Rolls-Royce engines. 

The settlement will help Qantas recover from the millions it lost following the incident. The airline was forced to temporarily ground its entire fleet of A380s for a series of inspections, and Joyce said the plane damaged by the explosion won’t return to service until February.

“Qantas and Rolls-Royce have had a long and successful commercial partnership spanning several decades,” the airline said in a statement. “Qantas looks forward to a continued strong relationship with Rolls-Royce on the basis of the settlement announced today.”

The compensation payment helped boost the airline’s expected underlying pretax profit for the year to June 30 to between A$500 million (£326m) and A$550 million (£359m), up from A$377 million (£246m) a year ago.

…… Qantas shares rose 0.8 per cent to AU$1.84 in afternoon trading.

This leaves Rolls Royce the task of settling with Airbus and some less costly settlements with Lufthansa and Singapore Airlines.

My estimate is that it will take another 2 to 3 quarters for most of these costs to have worked their way through Rolls Royce’s accounts. However RR will have to bear an increased and continuing service cost regime for some time to come for the Trent 900.

The Trent 1000  for the Dreamliner is still a long way off from generating real revenues for Rolls Royce.

It could be time to buy Rolls Royce again.

The Age of Fossil Fuel may be just beginning

June 3, 2011

A little bit over the top from Michael Lind in Salon but still fundamentally not wrong:

Are we living at the beginning of the Age of Fossil Fuels, not its final decades? The very thought goes against everything that politicians and the educated public have been taught to believe in the past generation. According to the conventional wisdom, the U.S. and other industrial nations must undertake a rapid and expensive transition from fossil fuels to renewable energy for three reasons: The imminent depletion of fossil fuels, national security and the danger of global warming.

What if the conventional wisdom about the energy future of America and the world has been completely wrong?

As everyone who follows news about energy knows by now, in the last decade the technique of hydraulic fracturing or “fracking,” long used in the oil industry, has evolved to permit energy companies to access reserves of previously-unrecoverable “shale gas” or unconventional natural gas. According to the U.S. Energy Information Administration, these advances mean there is at least six times as much recoverable natural gas today as there was a decade ago.

Natural gas, which emits less carbon dioxide than coal, can be used in both electricity generation and as a fuel for automobiles.

……

Two arguments for switching to renewable energy — the depletion of fossil fuels and national security — are no longer plausible. What about the claim that a rapid transition to wind and solar energy is necessary, to avert catastrophic global warming?

The scenarios with the most catastrophic outcomes of global warming are low probability outcomes — a fact that explains why the world’s governments in practice treat reducing CO2 emissions as a low priority, despite paying lip service to it. But even if the worst outcomes were likely, the rational response would not be a conversion to wind and solar power but a massive build-out of nuclear power. Nuclear energy already provides around 13-14 percent of the world’s electricity and nearly 3 percent of global final energy consumption, while wind, solar and geothermal power combined account for less than one percent of global final energy consumption. ….

In the meantime, it appears that the prophets of an age of renewable energy following Peak Oil got things backwards. We may be living in the era of Peak Renewables, which will be followed by a very long Age of Fossil Fuels that has only just begun.

Power generation from shale gas is here to stay

May 31, 2011

The capital cost of building different types of power plants is a reality that cannot be wished away:

November 2010 Capital costs for power plants

Gas fired combined cycle plant use the least capital of all power generation plants. With shale gas set to become even cheaper than natural gas and with gas fired plants having capacity factors well above 90% compared to the 25% of wind power or the 30% of solar plants, it is a no-brainer to conclude that wherever shale gas is available it is going to be used for power generation.

Where it is not available coal fired plants and nuclear plants will continue to be used.

Intermittent renewable power plants are going to need subsidies for a long time to come to get anywhere near the cost of electricity from gas. At best they could be useful to augment production of electricity but being intermittent cannot really contribute to reliable capacity.

Saab motors being degraded on life support – euthanasia would be better

May 9, 2011

For twenty years the Saab 9000 and the Saab 9.5 were my cars of choice until “old age” has forced me to the blend of comfort and power that a Mercedes represents.

But Saab Motors is now on life support and in the hands of a Victor Muller who resembles a quack doctor extracting every bit he can from a dying patient. Saab’s production has been halted while new transfusions of money are being desperately sought – from very strange and dubious Russian and Chinese sources. The employees continue to hope and their attempts to push back the day of reckoning is perfectly understandable. But the fundamental reality is that not enough Saab cars are bought and it has become too expensive for what it is. The technology is still superb but in the meantime the Saab brand is being dragged through mud and manure.

Euthanasia is preferable to this degradation of the brand.

The Chinese money is unlikely to be forthcoming.

Dagens Industri writes:

Saab’s affaire with Chinese Hawtai has led to questions in the Chinese media. Experts are cautious about the marriage, and it is feared it will be stopped by the authorities. Hong Kong-based Phoenix television station says on its site ifeng.com

“Saab is not Volvo. The established Chinese car companies are not interested in Saab, and therefore this contract has come between Saab and Hawtai, two companies that both are in need to get out of a difficult situation. But what are the chances that the agreement be implemented? “

The Chinese Commission on Development and Reform NDRC, has to approve major transactions between Chinese and foreign companies. “Just as when Tengzhong Heavy Industrial tried to buy the Hummer this agreement between Hawtai and Saab has not been reported to the NDRC in advance, and therefore it has not been approved. It is therefore difficult to say whether this project will be approved. Further, the establishment of a joint venture for the manufacture and sale of Saab Cars is even more difficult.”

In recent times there has been a very strict control on approval of joint ventures for the manufacture of complete cars. “Even the long discussed projects between Changan Mazda Guangzhou Automobile and Mitsubishi, between Changan and PSA Peugeot Citroen, and the proposed Volkswagen plant expansions in Nanhai and Jiangsu are all still waiting for approval. To think that Saab Cars, which does not have as much advanced technology, would be allowed into manufacture and sale in China is less likely.”

Industry observers think that Hawtai’s and Saab’s agreement on strategic cooperation may suffer the same fate as Tengzhongs purchase of Hummer, and ultimately not be anything at all, according to Phoenix. 

Even the South China Morning Post questioned whether authorities would approve the deal.

And in the meantime Saab suppliers have had to warn that they may be forced to lay-off their employees.
