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:

Poor quality fuel possible cause of Yak-42 crash – aviation source

02:15 08/09/2011 Poor quality of aviation fuel could be one of possible reasons for why the Yak-42 plane crashed in Central Russia on Wednesday, killing more than 40 people.>>

JUMBO JET EMERGENCY LANDING

The incident happened at Dallas Airport on Sunday 24 July 2011. An American Airlines Boeing 777-200 apparently had an engine fire just after takeoff, and was forced to make a U-turn and dump fuel before performing an emergency landing. You can hear the pilot’s voice in the video hereafter as well as a part of the transcript:

X-51A WaveRider speed duration record at around Mach 5 – May 26, 2010

The X-51A WaveRider maintained its speed for more than 3 minutes. The X-43A reached the speed of Mach 9.8 in 2004. However, that top speed lasted for only 10 seconds.

« The X-51 launched at about 10 a.m. from here, carried under the left wing of an Air Force Flight Test Center B-52 Stratofortress. Then, flying at 50,000 feet over the Point Mugu Naval Air Warfare Center Sea Range, it was released. Four seconds later an Army Tactical Missile solid rocket booster accelerated the X-51 to about Mach 4.8 mach before it and a connecting interstage were jettisoned. The launch and separation were normal », Mr. Brink said. (www.af.mil courtesy)
