Ignition driving system of high-overload test device used for solid-propellant rocket engine

Abstract

The invention discloses an ignition driving system of a high-overload test device used for a solid-propellant rocket engine, relates to an ignition driving system used for a solid-propellant rocket engine experimental apparatus and in particular to an ignition driving system used for a solid-propellant rocket engine under the high-overload rotation test condition, and belongs to the field of aerospace. The ignition driving system comprises a long-distance integrated console, an ignition power supply control module, a test controller, a relay driving module, a solid-propellant rocket engine and an ignition tool, wherein the relay driving module is fixed on a noseplate on the central axis plane of a rotary test bench, and the axial line between the relay moving contact C and the relay stationary contact D in the relay driving module is tangent to a rotary table top. The ignition driving system can reduce or eliminate the adverse effect of radial centrifugal inertia and tangential acceleration impact on the relay driving module in the ignition power supply loop under the high-overload test condition. The ignition driving system has high dynamic operating precision and can be used for reliably and safely carrying out a continuous ignition test on solid-propellant rocket engines under high-overload rotary conditions.

Description

technical field [0001] The invention relates to an ignition drive system for a solid rocket motor experiment device, in particular to an ignition drive system for a solid rocket motor under high overload rotation test conditions, belonging to the field of aerospace. Background technique [0002] The high maneuverability and high-speed rotation during the flight of modern missiles will cause the solid rocket motor on it to bear high overload, which puts forward corresponding requirements for the design and development of solid rocket motor. On the one hand, the overload acceleration will lead to an increase in the combustion rate of the propellant, which will induce an increase in the pressure of the combustion chamber and a shortening of the combustion time, and eventually lead to changes in the ballistic performance of the engine; on the other hand, high overload will seriously affect the movement of condensed phase particles. Deteriorating the working environment of the en...
