SOLUTIONS TO SAVE JET FUEL

Here is a video shot from the NASA Langley Research Center in Hampton, Virginia, where 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

RAFALE fighter aircraft flying

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.

MACH-20 AEROSPACECRAFT

New-York to Los Angeles in 12 minutes… It would have been a record-breaker, had it worked:

The DARPA and USAF FALCON project might give anybody the thrill of speed as this “aerospacecraft” has been designed to reach Mach 20 i.e. around 20,000 km/h; 5.6 km/s; 10,800 knots; or 12,400 mph depending on the air temperature, and the altitude which might be above at least FL900!

Unfortunately, the project seems to encounter major difficulties as the last test which unfolded on August 11, 2011 failed again. The previous one – also on an HTV2 – had failed in April. Click on the right-hand side picture to get further information on the first test. The Blackswift (HTV-3X)  had been designed by ATK; Boeing; Lockheed Martin; and Skunk Works to provided a strategic strike anywhere in the world within an hour. It was cancelled due to a lack of funds (see the HTV-3 shown in the following video):

 


 

  • DARPA stands for Defense Advanced Research Projects Agency
  • FALCON stands for Force Application and Launch from CONtinental United States
  • FL stands for Flight Level (FL x 100ft = altitude)
  • HTV stands for Hypersonic Test Vehicle or Hypersonic Technology Vehicle
  • RCS means here in the videos: Reaction Control System (and not Radar Cross Section)

BOEING 787 Dreamliner maiden flight to JAPAN

It was the first time a Boeing B-787 Dreamliner had taken off for Japan. The Japanese ANA – All Nippon Airways – has ordered 40 Boeing B-787-8; and 15 B-787-9. This video was shot a month ago as the wide-body jet airliner departed from Seattle on July 3, 2011:
