Rapid erection method and device for large-tonnage solid rocket

Abstract

The invention provides a rapid erection method for a large-tonnage solid rocket. In a rapid erection stage, flow output by a metering pump (1) simultaneously passes through a flow cut-off valve (3) and a speed control valve (4), then passes through a machine fluid throttling valve (8) and directly enters an erection execution element (10); in an erection speed reduction stage, the flow output by the metering pump (1) to the erection execution element (10) is reduced by reducing the opening degree of a valve port of the machine fluid throttling valve (8) according to an erection angle of a launch canister; and in a slow erection in-place stage, the flow cut-off valve (3) is closed, and the flow output by the metering pump (1) passes through the speed control valve (4) and the machine fluidthrottling valve (8) and enters the erection execution element (10). The invention further discloses a rapid erection device for a large-tonnage solid rocket.

Description

technical field [0001] The invention relates to a rapid erection method and device for a large-tonnage solid rocket, belonging to the technical field of hydraulic control. Background technique [0002] In the vertical erecting and launching equipment of existing rockets, proportional valves (or digital valves or servo valves, etc.) and variable pumps are generally used to adjust the erecting speed. Different erecting speeds can be realized by the swing angle of the plate. Although the above-mentioned erecting methods can meet the erecting requirements, the stand-alone and system structures that make up the erecting circuit are complex, the proportional valve (or digital valve or servo valve, etc.) The electronic control requirements of the components are high, the electromagnetic compatibility is poor, the control strategy and the software implemented are complex, resulting in a decrease in the reliability of the erection link, the hydraulic circuit is complex, and the basi...
