Four high-speed air vehicles adopting novel engine

Abstract

The invention relates to four high-speed air vehicles adopting a novel engine. For the flying height and speed limit of an existing airplane, by adopting a novel turbofan engine and a combination of the novel turbofan engine and a novel rocket engine, the flying height of a supersonic airliner can reach 20-35 km, the Mach number of the supersonic airliner can reach 2-4, the flying height of a hypersonic unmanned aerial vehicle can reach 35-50 km, and the Mach number of the hypersonic unmanned aerial vehicle can reach 5-7. For single use of an existing carrier rocket, a horizontal rising-falling combined dynamic double-body rocket releases a hanging rocket when the flying height reaches 28-50 km and the Mach number reaches 4-7 and then returns to land, and therefore repeated use of the carrier rocket is achieved. For the problem that the research difficulty of a heavy carrier rocket is high, an economical and applicable carrier rocket is constructed by adopting three novel rocket engines. The four high-speed air vehicles have the advantage that aviation and spaceflight are combined integrally and are wide in application range.

Description

technical field [0001] The invention relates to four types of high-speed aircraft with novel engines, and belongs to the technical field of high-speed aircraft such as supersonic passenger planes, hypersonic unmanned aerial vehicles, horizontal take-off and landing launch vehicles, and economical and applicable launch vehicles. Background technique [0002] Civil aviation airliners generally cruise at a Mach number of 0.85 at an altitude of 10 km. The first-generation supersonic airliner consisting of the "Concorde" of Britain and France and the "Figure 144" of the former Soviet Union cruises at a height of 15-18km with a Mach number of 2.02-2.35. Military aircraft can also fly higher and faster. The development direction of aviation technology is to make aircraft fly better, higher and faster. [0003] Launch vehicles have many advantages and have successfully sent satellites, spaceships, and space stations into space. However, the launch vehicle has the disadvantage of ...
