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:

Pointing lasers at aircraft will cost offenders big time

Pointing lasers at aircraft can cost pilots their lives. The FAA has decided to increase the penalty. This prank is to cost the offenders a hefty fine – up to $11,000. Some pen-shaped laser pointers have been reported around a thousand times in the USA in 2011, and 2,836 incidents were reported last year.

It may seem a harmless prank. However, when a laser pen user aims at an aircraft, it turns into a dangerous hazard as the laser light is reflected everywhere. When the beams re reflected into the pilots’ eyes, the can get blind, and cause a crash.
