Model rocket is a kind of model aircraft, is a kind of unmanned aircraft for sports, but also a large real rocket in structure, shape similar to the miniature or small rocket, it has the real rocket ignition launch, air flight, parachute recovery and other functions. It is one of the important ways to popularize space knowledge and cultivate and bring up space reserve talents to carry out model rocket movement widely among young people. The development direction of the model rocket is to fly higher, fly more stably, have a higher degree of vertical launch, have a moderate recovery speed and smoothly fall on the designated position, and the overall weight of the rocket is lighter. There are many types of model rockets on the market, but it is the first time that the two more commonly used chips, Arduino and MPU6050, have been combined into practice. The innovation points are: 1. Model rocket achieves attitude control The traditional model rocket cannot achieve attitude control, and the model rocket innovatively introduces MPU6050 to make this idea come true. 2. The second-level umbrella opening adopts a compact and convenient mercury switch. The second-level umbrella opening is controlled by a single-chip microcomputer and adopts a compact and convenient mercury switch. 3. A new type of recoverable two-stage model solid rocket. A multifunctional portable and adjustable model solid rocket launcher, the adjustable plate of the launcher can adjust the position of the telescopic rod, which can adapt to different rocket diameters, and the guiding telescopic rod can match the heights of different rockets. A fixed base plate may enhance the stability of the device.
