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:

BERNOULLI’S PRINCIPLE

Bernoulli's principle and Venturi tubeBernoulli’s principle  states that when  a fluid flowing through a tube reaches a constriction or narrowing  of the  tube  the speed  of  the  fluid  passing through the constriction is increased and its pressure is decreased.

HOW AIRPLANES FLY ?

What makes an airplane get off the ground and stay in the air? Easy to understand, the film combines animation and live sequences to explain everything about basic aerodynamics. Forces of lift, weight, thrust and drag are shown in relation to flight.
