Future aircraft consume very little fuel

The Massachusetts Institute of Technology (MIT) team has successfully researched new aircraft models, which could revolutionize civilian aircraft. The model of this type of aircraft flies almost without noise and energy consumption drops by 70%.

Aircraft D are close to each other.

Since November 2008, MIT has won a NASA bid to research and build a civilian aircraft model for the future.

The program is known under the name 'N + 3' (implying the creation of the next three generation aircraft), aimed at studying key technologies.Among them, there was the improvement of the body of the flying device and the invention of fuel-efficient engines, laying the basis for making aircraft more suitable for ecological conditions in 2035.

Professor Ed Greitzer, MIT's Department of Aerodynamics and Astronautics told journalists: "Our basic goal is to study aircraft that meet NASA's strict standards, and at the same time. responding to changes in the aviation industry by the time of 2035, when aviation travel and transport doubled today. '

The scientist added: 'Unlike the automobile industry, which underwent constant changes during the past 50 years, half a century ago, the shape of the aircraft was almost the same' to talk about maintenance. in the design of aircraft body and wings.

Pursuing their ideas, the MIT team created two models of flying devices of the future.The first model is D (short for 'double bubble' , meaning 'double bubble' ) carrying 180 passengers, borrowing the ' Boeing 737' 'intestine ' , currently used for domestic flights. The second model is H (short for ' Hybrid wing body' , which means that the hybrid wing body) carries 350 passengers, scheduled to replace the '777' aircraft, used for international routes.

Unlike most transport aircraft, the air enters the engine at a high speed, in the structure of the model aircraft D air is sucked in more slowly to pin the fuselage.As a result, fuel consumption will be less, but traction remains constant.In addition, the aircraft can take off and land on much shorter runways.The downside of this solution is the larger and heavier engine.

When building aircraft in the T model, the designers changed the shape of the aircraft completely.Instead of a body, the plane has two bodies attached to each other like two soap bubbles.The engine and wings are placed on the rear of the body.

Both models were presented to NASA last month, in the framework of a $ 2.1 million contract to incorporate ecological and efficiency concepts, laying the foundations for aerodynamic studies. in the next 25 years.

Designers must not only meet NASA's requirements, but in the future, it must be outlined for the aviation industry of valuable and feasible developments.

The team is proposing two projects: one is to apply high technologies, reduce fuel consumption by up to 70%;secondly, improving materials to make modern aluminum aircraft, reducing fuel to 50%.

The famous Russian flying designer Renat Baramíkov commented: 'The recent achievements of American airlines are impressive. Reducing fuel consumption by 70% is a step that can use two words as 'great'. But the reverse side of the medal is safety. Designing engines according to new concepts, under new aerodynamic conditions will also arise safety requirements. New large-sized engines also have limitations in their ability to work long-term and this is a special concern . '
