The cost of flights can be greatly reduced Bashny.Net

As you know, the price of fuel is the lion's share of the cost of air travel. To solve this problem, the researchers designed a "Double Bubble" ("Double bubble").

A fuselage located behind the engines, reduced wingspan, the raised nose allows this 180-seater aircraft burn 70% less fuel than a standard Boeing 737, while creating less pollution and noise.

NASA hopes that the new ship will be ready by 2025 when it is expected that air traffic will almost double in comparison with today's indicators. The design concept of the liner for the practical test will be ready, most likely before the end of the summer. If the planes start to use renewable energy, fuels with low emission of harmful exhaust gases, or biofuels, this will reduce the total cost of travel, as well as to reduce the price of the tickets.
