Synchronous detonation device for hypersonic aircraft component separation wind tunnel experiment

Abstract

The invention discloses a synchronous detonation device for a hypersonic aircraft component separation wind tunnel experiment. The synchronous detonation device comprises a synchronous trigger unit (1), a detonation control unit (2) and a constant current unit (3). The synchronous detonation device solves the problems of time synchronization of a detonation process and a wind tunnel effective experiment, monitoring of the detonation process and the like, avoids the problem of erroneous detonation induced by strong electromagnetic interference of wind tunnel aided high-power equipment, provides an experimental foundation for verifying the feasibility of an aircraft component separation scheme with a wind tunnel, allows the component separation verification scheme not to be limited to actual flight experiments, and reduces the aircraft research and manufacturing cost and cycle.

Description

technical field [0001] The invention belongs to the technical field of high-speed aircraft wind tunnel experiments, and in particular relates to a synchronous detonation device for hypersonic aircraft component separation wind tunnel experiments. Background technique [0002] The separation of hypersonic aircraft components includes: the separation of the inlet protective cover, the separation of the booster stage and the cruise stage, and the separation of the cabin wing. The separation of hypersonic components is different from the separation of rocket fairings. Since the separation of rocket fairings has already rushed out of the atmosphere during separation, the numerical simulation and ground test of the ejection process are relatively simple. In the separation experiment of hypersonic aircraft components, due to the aerodynamic force, it is difficult to predict the trajectory of the separated components numerically, and the cost of the actual flight test is too high.
