Parafoil autonomous homing control system for rocket booster recovery

Abstract

The invention provides a parafoil autonomous homing control system for rocket booster recovery. A switching box is started to be used as an interface of the parafoil autonomous homing control system and a rocket main body; after a power distribution ignition controller is electrified, according to a certain time sequence, each equipment is controlled to be electrified, and initiating explosive devices are controlled to be detonated; a homing controller operates a homing algorithm, and controls the parafoil flying direction; a positioning and orientation instrument uses double antennas to perform direction measurement and positioning; meanwhile, a gyroscope and an inclination angle sensor are integrated at the inside; a data transmitter is in charge of communication between the parafoil autonomous homing control system and a ground station; a servo control device comprises a motor, a driver and a transmission mechanism, and is used for parafoil operation control; a control power supplyprovides control electricity required by the whole control system; and a dynamic power supply provides dynamic power required by the initiating explosive devices and the servo control device. The control system integrates the functions of navigation, guidance, data transmission and initiating explosive device explosion initiation, is matched with a booster interface at the same time, and forms theuniversal parafoil autonomous homing control system applied to rocket booster recovery.

Description

Technical field

[0001] The invention relates to a parafoil autonomous homing control system used for rocket booster recovery, belonging to the field of spacecraft recovery control, and in particular to a spacecraft recovery autonomous homing control system. Background technique

[0002] Rocket booster is a small rocket engine that quickly flies away from the launch pad and accelerates to a predetermined flight speed when the rocket is launched. When the booster completes its mission, it will leave the rocket body, and the separated booster will be uncontrolled. The state of free fall, the landing speed is large, and the falling points are scattered. Due to historical reasons, my country's existing launch sites are all built inland, and their tracks often pass through densely populated areas. The huge impact force during the fall of the separated body debris makes the rocket body possible a huge explosion; and the leakage of the residual propellant in the propellant tank after fa...

Examples

Embodiment Construction

[0028] Such as figure 1 Shown here is a parafoil autonomous homing control system for rocket booster recovery of the present invention. It includes: start-up transfer box, power distribution ignition controller, homing controller, positioning and orientation instrument, digital transmitter, and servo control Device, control power supply and power supply;

[0029] The start-up adapter box is used as the interface between the parafoil autonomous homing control system and the overall rocket, and is used to receive the overall rocket power-on command sent by the upper level, and control the power distribution ignition controller on and off according to the rocket overall power-on command switch; The starter adapter box is powered on before the rocket is launched, and waits to receive the overall power-on instruction of the rocket. When the rocket booster is separated, the starter adapter box receives the power-on instruction to power on the power distribution ignition controller;
