A universal booster that falls off on its own without disturbance

Abstract

The invention discloses a universal booster capable of disengaging automatically without causing disturbance. The universal booster capable of disengaging automatically without causing disturbance comprises a rocket engine, a locking and unlocking device and a boosting frame, wherein the boosting frame is used for achieving the positioning function for the rocket engine and the locking and unlocking device, the rocket engine and the locking and unlocking device are fixed together and combined so as to bear the axial overload of the booster, and the boosting frame is connected with or separated from a carrier through the locking and unlocking device. The boosting frame is matched with a sleeve at the tail end of the carrier, an igniter is used for ignition, a grain is burnt and then generates thrust, a delayed gunpowder pipe is ignited at the same time, a powder flask of the locking and unlocking mechanism is ignited through the delayed gunpowder pipe after the whole grain is burnt out, a micro explosive reaction is generated in the powder flask, a push rod is pushed through a lead screw and a rotary disc to move, the push rod is pulled back in the radial direction of the rotary disc, the boosting frame and the carrier are not constrained any more, and the lead screw penetrates through a sealed bottom at the front end of the boosting frame and collides with the carrier, so that separation is achieved. After separation, a parachute placed in a frame groove of the boosting frame in advance is exposed and opened, and then recovery of the booster is achieved.

Description

technical field [0001] The invention belongs to the application field of rocket engines, and in particular relates to a universal booster that falls off by itself without disturbance. Background technique [0002] Solid rocket motor technology is relatively mature and reliable, and it has been widely used in space shuttles, rockets, missiles and other carriers or weapons, greatly increasing the range, and solid rocket boosters have become an indispensable part of its flight. For many existing weapons such as artillery shells and unmanned aircraft, their combat effectiveness is greatly reduced due to their limited range. The rocket booster mainly refers to a repeatable and general-purpose booster that can be installed on the tail of the carrier, provide thrust, and fall off by itself without disturbance. [0003] In the existing published technical literature, the article "Design and Analysis of Micro Booster" (Northern University of China, 2009, master's degree thesis) uses...

AI Technical Summary

Problems solved by technology

The existing booster separation system introduced in the literature and the novel booster separation system of design have the following defects: the first, the power supply system of the carrier needs to be powered when the booster is separated, and the control system sends control signals, while ordinary ammunition does not There is no power supply and control system; second, the booster uses explosive bolts, explosive belts and other components that are difficult to control precisely, so that the carrier will be disturbed during the separation process. Since the rocket has a control system, it can restore its balance after being disturbed. For ordinary ammunition without a control system, the disturbance during separation is likely to cause the movement of the ammunition to diverge and the posture to be out of balance; Low, large quantity, if too many one-time consumables are used, it is difficult to get a large area of ​​use on ordinary ammunition
