Rotary acceleration type magnetic suspension electromagnetic propulsion test system and method

Abstract

A rotary acceleration type magnetic suspension electromagnetic propulsion test system comprises a vacuum rotary acceleration section, a test section, a magnetic suspension electric propulsion system,an energy storage and distribution system, a test gas medium regulation and control system and a test data measurement system, the test model obtains an initial speed through rotation acceleration andenters a test section, a magnetic levitation electric propulsion system is arranged in the test section, and the test model is subjected to speed control through the magnetic levitation electric propulsion system to simulate a flight trajectory; the energy storage and distribution system and the test gas medium regulation and control system are both arranged on the outer side of the test section,the energy storage and distribution system is used for supplying power to the magnetic levitation electric propulsion system and the test gas medium regulation and control system, and the test gas medium regulation and control system is used for regulating gas pressure and temperature in the closed test section; the test data measurement system is used for collecting test model motion data. The problems that an original test equipment test model is limited in size, test gas is polluted, and the sky-ground difference limits the aircraft technology are solved.

Description

technical field [0001] This patent provides a rotational acceleration type magnetic levitation / electromagnetic propulsion test system and method. The system belongs to the technical field of aerodynamic testing. Background technique [0002] Wind tunnel test is an important means for people to carry out research on aerodynamics and aircraft on the ground. It is by relying on wind tunnel test that the basic laws of aerodynamics can be confirmed, the actual shape of the flow around various aircraft can be determined, and the air flow of aircraft can be determined. Numerical results for dynamic / thermal properties can be more accurate. However, with the advent of hypersonic flight, we found that although we are constantly improving wind tunnel test technology and test equipment, such as high-enthalpy shock wave wind tunnel, arc wind tunnel, combustion wind tunnel, etc., none of the equipment can Covers the entire flight envelope of the aircraft. [0003] With the emergence of...

AI Technical Summary

Problems solved by technology

Due to the limitation of the straightness of the track itself and the inevitable protrusion of the track itself in the traditional rocket sled, there must be a gap between the slider itself and the track, so that the slider will vibrate at high speed due to aerodynamic force and load during the movement of the rocket sled. The continuous impact on the track will cause serious damage to the rail slider, and the more serious consequence is that the slider will detach from the track, resulting in the failure of the test
