Model rocket convenient to recycle

Abstract

The invention relates to a model rocket convenient to recycle. The model roket comprises a rocket head and a rocket body, and a sensor and a parachute are arranged in the rocket, and the sensor is connected to an adjusting mechanism. In the operation process of the rocket, the adjusting mechanism adjusts the rocket head to be in two states, wherein one state is that the rocket is in an upright posture during lift-off, and when the sensor does not detect the change of the rocket attitude, the adjusting mechanism adjusts the rocket head to be in the working state of being assembled on the rocketbody; the second state is that the posture of the rocket is changed when the rocket falls down; the sensor detects the attitude change of the rocket, the adjusting mechanism adjusts the rocket head to be in a separation state of separating from the rocket body to release the parachute according to a signal detected by the sensor. The model rocket is stable in structure and reasonable in layout, the rocket head and the rocket body can be separated in time and the parachute can be released when the falling posture of the rocket is changed after the rocket lifts off, parachute ropes of the parachute can be wound when the rocket is about to fall to the ground, resistance is increased, landing impact force is reduced, and the risk that the rocket is damaged by falling is effectively reduced.

Description

technical field [0001] The invention relates to the field of models, in particular to a model rocket that is easy to recover. Background technique [0002] Model rocket experiments are the foundation of the development of rocket technology, but from the current international rocket launch situation, the fundamental constraint on rocket experiments lies in the high cost of rocket launch. Each rocket launch consumes huge human, material and financial resources. However, Each rocket is a one-off product, which makes many reusable resources go to waste. [0003] Conventional model rockets are made of light-weight materials, and are separated by conventional engine back-injection, which has poor structural stability and cannot be controlled during the launch process. The general model rocket uses a B6-4 solid engine. The engine adopts a reverse injection separation method. When the propellant is burned out, it enters a 2-second delay, and then the reverse injection fuel is burne...

AI Technical Summary

Problems solved by technology

[0002] Model rocket experiments are fundamental to the development of rocket technology, but judging from the current situation of international rocket launches, the root of restricting rocket experiments lies in the high cost of rocket launches. Every rocket launch consumes huge manpower, material resources, and financial resources. However, Each rocket is a one-off product, which makes many reusable resources go to waste

[0003] Conventional model rockets are made of light materials, and are separated by conventional engine reverse injection. Their structural stability is poor and they cannot be controlled during launch.

The general model rocket adopts the B6-4 type solid engine, which adopts the reverse injection separation method, and enters a 2-second delay after the propellant is burned, and then performs reverse injection fuel combustion, because the engine sprays high-heat flames into the rocket body , it is easy to burn the internal structure and landing device, causing the model rocket to land and crash. The problem of destruction, the parachute is large, and the resistance is large, causing the model to be delayed and blown away by the wind, which increases the difficulty of finding and the risk of loss
