A Model Rocket That's Easy to Recycle

Abstract

The invention relates to a model rocket which is easy to recover, which includes an arrow and a rocket body. The arrow is equipped with a sensor and a parachute, and the sensor is connected with an adjustment mechanism. When the attitude of the rocket is upright when the sensor does not detect a change in the attitude of the rocket, the adjustment mechanism adjusts the arrow to be in the working state of being assembled on the rocket body. The detected signal adjusts that the arrow is in the disengagement state of releasing the parachute from the rocket body. The structure of the present invention is stable and the layout is reasonable, and it can realize that after the rocket is lifted into the air, when the falling attitude of the rocket changes, the arrow and the rocket body can be separated in time, and the parachute can be released, so that the rocket can be released. When it is about to fall to the ground, the parachute cord is retracted to increase the resistance and reduce the landing impact, effectively reducing the risk of the rocket crashing.

Description

technical field [0001] The invention relates to the field of models, in particular to a model rocket which is easy to recover. Background technique [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, Every 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, which has poor structural stability and is uncontrollable 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 f...

[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
