A vehicle-mounted missile launching double-arc deflector

Abstract

The invention belongs to the technical field of missile launching and especially relates to a device for performing fuel gas guidance for vehicle-mounted missile launching. According to the technical scheme, the vehicle-mounted missile launching double-arc fluid director comprises a fluid director and a base; the fluid director comprises an upper linear segment, a small arc segment, a big arc segment and a lower linear segment which are connected with each other in turn; the base is used for connecting the fluid director with a launcher. According to the invention, the problem of ultrahigh horizontal impact of the fuel gas flow to the launcher in the process of low-angle missile launching can be solved; the guidance of a double-arc fluid guiding surface to the fuel gas flow is adopted for preventing the ablation and impact of high-temperature high-rate fuel gas flow to the missile and the launcher while lowering the maintenance cost of the launching equipment; due to the design of the double-arc fluid guiding surface, the horizontal push force endured by the launcher is reduced and the stability of the launcher is increased, so that the launching precision, the launching efficiency and the reliability can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of missile launching, and in particular relates to a device for conducting gas diversion for vehicle-mounted missile launching. Background technique [0002] At present, the main battle weapon system of a certain air defense missile adopts a vehicle-mounted mobile dual-mounted launch, which requires missiles to be launched within a range of 360 degrees and a height of 19.5 to 65 degrees. The high-temperature and high-speed gas flow generated during launch directly affects the launch accuracy and the stability of the launch device, especially the rewind flow during launch, which will directly erode the tail of the missile and even cause the launch device to be damaged. In order to prevent the high-temperature and high-speed gas flow from eroding the missile and the launch system, a deflector device is usually installed at the front of the launch vehicle to ensure the smooth drainage of the gas flow.

Problems solved by technology

Moreover, due to the high thrust of the missile, when the launch vehicle is launched at a low angle and the nozzle of the rocket engine is facing the front end of the launch vehicle, the launch vehicle is subjected to a large horizontal thrust, and the launch vehicle is very likely to move horizontally, which will damage the stability of the launch vehicle. , causing the weapon system to fail to launch
