In the field of civilian passenger planes, it is mainly the US Boeing and Europe’s Airbus occupied the market, but as long as everyone carefully observed whether Boeing or Airbus, or the country in my country has a large development of civilian passenger planes, developed Most of the passenger aircraft are all as follows. In fact, it is a conventional layout such as “cylinder” “wing” for decades. Such layout is very solid and reliable. However, after several decades of development, the potential of such a design has already been discovered, and the new layout needs to appear.
Previously, my country’s Northwestern Polytechnical University launched several self-exemption of flying wing large aircraft models, it was really bright. From the model (below) of the exposed NPU 300 civilian big aircraft (below), the lading of the machine is consistent with the layout of the US B-2 bomber, and it uses a flying wing layout. The advantage of such layouts is that the aircraft is in the middle of the high-speed, and the resistance is small, thereby saving fuel. At the same time, the lift generated by such layout is larger than the strength of the conventional layout, and it can improve the take-down performance of the aircraft.
As a B-2 bomber as a fighter, there is still a role in stealth, the flying wing is the strongest in the aerodynamic layout of the aircraft in the aircraft. Of course, the NPU 300 is used for civilian, so it is impossible to put the engine in the body like a B-2 bomber, but in turn on the back. Although this practice looks away from the rebellion, it is actually available.
The Arad of Arad, Germany, Germany, the World War II, was using this layout. In the beginning, Germany’s design is mainly considering the Ar.e555 fighters to carry more bombs, so the engine is placed on the back, today’s NPU300 civil airplane is also in this consideration, so this is used . Place the engine in the back of the aircraft, is not an attempt to have a cardiogramine in my country. It is very likely that this is my country’s new fighters in the future.
