Abstract

The invention discloses a system and a method for measuring the flight attitude and surface temperature of an ultra-high-speed aircraft, and belongs to the technical field of ultra-high-speed aircrafttest parameter measurement. The system comprise a laser for illuminating the ultra-high-speed aircraft, a collimation and beam expanding device used for improving the uniformity of a light source, the ultra-high-speed aircraft which simulates the shape of a rocket, a first beam splitter which is used for splitting ultra-high-speed aircraft signal light into two beams, an aircraft attitude measurement module used for receiving the signal light emitted after the laser irradiates the aircraft and measuring attitude parameters of the aircraft, an aircraft surface temperature measuring module which is used for receiving the radiation light generated after a head of the ultra-high-speed aircraft is pneumatically heated and measuring the aircraft surface temperature, a time sequence control module used for controlling the laser to emit light and receiving CCD synchronous exposure of the signal light; and a calculation module used for obtaining attitude parameters and surface temperature of the aircraft, wherein one beam of the two beams is received by the aircraft attitude measurement module, and the other beam is received by the aircraft surface temperature measurement module.

Description

technical field [0001] The invention relates to the technical field of ultra-high-speed aircraft test parameter measurement, in particular to a system and method for measuring the flight attitude and surface temperature of an ultra-high-speed aircraft. Background technique [0002] With the development of aerospace technology, the speed of aircraft is getting higher and higher, and the frequency of going to and from space is increasing. The shape of the ultra-high-speed aircraft is precisely designed, and the aerodynamic parameters under different attitudes are quite different. Developing aircraft attitude measurement technology, simulating the space environment, and carrying out ground tests of ultra-high-speed aircraft are of great significance to the design and attitude control of aircraft. When the aircraft flies at super high speed, due to the viscous stagnation of the high-speed airflow on the surface of the aircraft, a large amount of frictional heat is generated, fo...
