SOLUTIONS TO SAVE JET FUEL

NASA Langley Research Center in Hampton, Virginia – New energy-efficient airplanes could be designed. Researchers work on designs for viable commercial aircraft which could leave a low to zero carbon footprint.

In order to save jet fuel, they look at new concepts, processes, and designs that could be lighter. They try to reduce drag, and they try to increase the propulsive efficiency. For this purpose, they try to get rid of metallic airframes, and parts as often as possible.

For instance NASA has a newer composite 10 percent lighter than carbon fiber composite. This advanced material is called “Pultruded rod stitched efficient unitized structure” or PRSEUS.

The new sleeker designs look like large wings without any traditional tube-shaped fuselage in the central part since it is blended with the wings. These futuristic designs are more fuel efficient as the more lift the plane has, the less it consumes fuel.

The researchers also look at new energy sources as it is showed in this video, and in the end there is further information about the NextGen project which could save fuel too, thanks to this new form of air traffic management:

 

RAFALE likely to be turned down in UAE fighter aircraft bid

According to the comments of His Highness General Sheikh Mohammed bin Zayed Al Nahyan, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the UAE Armed Forces, the French Dassault RAFALE multirole fighter aircraft might be rejected as he was paying a visit to the 12th Dubai International Airshow.

About the Rafale deal, he said that Dassault seemed unaware that all the diplomatic and political will in the world could not overcome uncompetitive and unworkable commercial terms.

Dassault was deemed to race ahead in this $10-billion sale to the United Arab Emirates. The contest has taken a dramatic turn as EADS Eurofighter/Typhoon seems to receive a decisive momentum, and the Boeing F-15 and F-18 programmes would be back on track in this competition.

The Rafale performances in Libya were thought to have outclassed the other allied fighter aircraft, and it clearly headed above the competition indeed. However, some commercial negotiations would have failed. To be continued…

BOEING 767 BELLY-LANDING in Warsaw

November 1, 2011 – A commercial aircraft performed an emergency landing onto Frederic Chopin International Airport two hours ago. The LOT Polish Airlines B-767 that had taken off from Newark had then been circling over Poland’s capital for an hour as a landing gear failure had been reported. The belly-landing unfolded perfectly, and the firefighters responded immediately. No casualties have been reported among the crew members and the 230 passengers.
