Abstract

The invention discloses a wide-speed-range aircraft waverider configuration design method, which comprises the following steps: determining a free incoming flow condition based on two-stage injection stage separation, a reference cone length and a shock wave angle for designing a waverider, and obtaining a supersonic-speed circular cone reference flow field model required for designing the waverider; according to two-stage injection stage separation requirements, initial parameters of half waverider are determined, and the whole waverider is obtained through mirror symmetry of the half waverider; according to the two-stage injection stage separation requirement, the datum line type of the half waverider is determined, the datum line type of the half waverider specifically comprises a horizontal line segment, a lower opening parabolic segment and an upper opening parabolic segment, and datum line type functions of the horizontal line segment, the lower opening parabolic segment and the upper opening parabolic segment are obtained according to the initial parameters; according to the initial parameters and the datum line linear function, the wave rider base body is obtained through calculation based on the supersonic speed surrounding cone datum flow field model needed for designing the wave rider by means of the cone guided shock wave theory, and the configuration process is simple and efficient.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a configuration design method for a waverider body of a wide-speed range aircraft. Background technique [0002] Since the 21st century, with the increasing demand for deep space exploration, space station construction and space travel around the world, the reusable space-ground transportation system has been extensively studied. In order to realize the space-to-ground transportation, the aircraft needs to have the ability to fly across the airspace at a wide speed range, but there are very few mature wide-speed field aircraft that can be used as part of the space-to-ground transportation system. [0003] As a (hyper)sonic aircraft with high lift-to-drag ratio aerodynamic performance, the waverider has the potential to be the base of a wide-speed aircraft. The variable-span wide-speed-range booster aircraft based on the waverider substrate not only has the high lift-to-drag r...
