There are already several projects aimed at creating solutions to reduce fuel consumption by passenger aircraft, from new ballasts through hybrid drives to new wing designs. NASA has just introduced its concept of the latter.
Airplanes consume large amounts of fuel, so for airlines this is a fairly important item in the expense that would certainly be reduced. Thanks to the efforts of NASA engineers, it will be possible in the near future. Space agency specialists have developed a new wing design, much thinner than previously used, which, according to calculations, can reduce fuel consumption by as much as half.
Wings are the most important element of any airplane, providing its carrying power. So the bigger the machine, the bigger the wings have to be so that the mass can tear off the ground. The problem is that the larger the wings, the greater the weight of the whole plane, and also the air resistance, which results in higher wear and tear, higher emissions of harmful compounds to the atmosphere, and higher operating costs. One way to reduce the wings is to increase their length and width. Such an idea would not work, however, because the structure of the wings would collapse under its own weight.
NASA together with Boeing engineers coped with this problem by using a truss stiffener and an additional bracket. The spacing of the wings is half that of a normal airplane, and at the same time they are lighter. As a result of these changes, fuel consumption during simulation is reduced to half.
