The present invention proposes a weight-reducing wing of an upper-atmospheric ultra-high-speed cruising aircraft, comprising: a plurality of wing plates with the same thickness and width; a group of connecting rods; wherein the connecting rods connect the plurality of wing plates They are connected together in sequence, and there is a through groove between the wing plates to form the weight-reducing wing. The current aircraft weight reduction design mainly involves aviation flight area (0km~20km), adjacent space (20km~100km) and outer space (300km~). Redesign technology. The present invention can also save materials while realizing weight reduction, and can also keep the aerodynamic performance unchanged or even enhanced. development and utilization.
Description
technical field [0001] The invention belongs to the field of aerodynamic design of high-altitude ultra-high-speed aircraft, and in particular relates to a weight-reducing design scheme for a wing of an upper-atmosphere ultra-high-speed cruise aircraft. Background technique [0002] In the field of aerospace engineering, an effective way to reduce fuel consumption and improve energy efficiency is to reduce the weight of aircraft. For example, for a Boeing 787 commercial aircraft, a 20% weight reduction rate will increase fuel efficiency by 10% to 12%. For another example, the final velocity that the spacecraft-rocket combination can achieve is proportional to the ratio of the initial mass (the sum of the spacecraft mass, the mass of the rocket body and the mass of the fuel) to the final mass (the sum of the mass of the spacecraft and the mass of the rocket body). Therefore, in order to increase the final launch velocity, the mass of the spacecraft and the rocket body should ...
