Abstract

The application discloses an ignition safety system of a multistage rocket engine and a detection method of the ignition safety system. The ignition safety mechanism of a multistage rocket engine comprises a ground testing and launching control system, an N-stage ignition safety mechanism and an N-stage intelligent detection combination, wherein the N-stage intelligent detection combination is used for detecting and recording the operating states of corresponding all stages of ignition safety mechanisms, and transmitting the operating states to the ground testing and launching control system;and the ground testing and launching control system is used for detecting the insurance states and the operating states of the ignition safety mechanisms and receiving the recorded operating state ofthe ignition safety mechanisms, detected by the N-stage intelligent detection combination, and according to the insurance states and/or the operating states of the ignition safety mechanisms, detecting the safety states of the ignition safety mechanisms. Through the adoption of the ignition safety system of the multistage rocket engine and the detection method of the ignition safety system disclosed by the invention, all the stages of the ignition safety mechanisms are connected in series, so that the design complexity of a cable network is simplified, and the weight of the cable network is reduced.

Description

technical field [0001] The present application relates to the field of rockets, in particular to an ignition safety system of a multi-stage rocket engine and a detection method thereof. Background technique [0002] Multi-stage rocket engines generally ensure the safety of use by controlling the ignition safety mechanism, prevent accidental detonation of the engine, and ensure the safety of personnel, launch equipment, site facilities and aerospace vehicles. In order to improve the operation and control safety of the ignition safety mechanism, the relay logic mutual exclusion interlocking control principle is generally adopted, and the state of the ignition safety mechanism is divided into an insurance state and a working state, and the two states are logically mutually exclusive. The current detection methods for multi-stage rocket engines are as follows: figure 1 shown. The ground measurement and control system connects the safety status (K1bx, K2bx...KNbx) and working s...
