World’s top aircraft engineers are asked to design jets which consume less fuel and must have the capability to fly cleaner and quieter. Jets with such features and specification will definitely solve the current hardest problems in commercial aviation. The project is initiated by NASA. Here are some jets proposed by different aircraft engineers for future.
1. Box Wing Jet:
To overcome the fuel consumption problem in jets Lockheed Martin engineers proposed a Box Wing Jet design. With looped-wing configuration design the Lockheed Martin engineers are sure that lift-to-drag ratio will increase by 16 percent. With such increase in lift-to-drag ratio it will be possible to reduce the fuel consumption.
2. Supersonic Green Machine:
Lockheed Martin engineers displayed Supersonic Green Machine to avoid the noisy, inefficient and highly polluting supersonic aviation. Supersonic jet series ended its operation in 2003 because of noisy flights but this time Martin engineers came up with a different supersonic design. The Green Machine can switch into conventional turbofan mode during takeoff and landing with the help of variable-cycle engines. In engines Combustors will reduce supersonic noisy effect.
3. Boeing SUGAR Volt:
Boeing SUGAR Volt is designed to overcome fuel consumption problem. The SUGAR conserves fuel with battery packs and electric motors present in it hybrid propulsion system. During take off Boeing SUGAR consumes energy both from jet fuel and batteries but at a constant altitude batteries are enough.According to Boeing’s principal investigator, “By making the wing thinner and the span greater, you can produce more lift with less drag.” With the combination of high-lift wings, hybrid powertrain and open-rotor engines SUGAR Volt can perform 55 percent more efficient.
