Launching mechanism and multi-stage water rocket

Abstract

The invention relates to a launching mechanism and a multi-stage water rocket. The launching mechanism comprises a first sliding block, a second sliding block and a control rotating disc which rotates when controlled. The first sliding block is arranged in the second sliding block in a nested mode, a first preset position of the control rotating disc is connected with the first sliding block, a second preset position of the control rotating disc is connected with the second sliding block, the control rotating disc drives the first sliding block and the second sliding block to slide relatively when rotating so as to increase or decrease the coincidence area of a bayonet of the first sliding block and a bayonet of the second sliding block, and thus a to-be-clamped object placed in the bayonets can be conveniently loosened or clamped. According to the launching mechanism, loosening and clamping of the object can be controlled through simple sliding, and automatic control is achieved through an external motor, so that a flight control system precisely controls launching, and the problem that the tightness degree can not be controlled in manual object clamping is solved; the launching mechanism is simple in structure and light in weight.

Description

technical field [0001] The invention relates to a launching mechanism and a multistage water rocket. Background technique [0002] The water rocket is a toy designed using mass ratio and air pressure. It is also one of the famous cases in physics teaching. It can cultivate students' interest in physics learning, and the physical principles contained in it are an important basis for understanding mechanics in physics. . [0003] Present water rocket, adopts water spray as power to promote rocket to advance, is to utilize discarded drink bottle to make power capsule, rocket body, arrow, empennage, parachute. Pour one-third of the water, use the pump to inflate the air to a certain pressure and launch it. It uses the mass ratio of water and air (the density of water is 771 times that of air), and the compressed air sprays water from the nozzle at the tail of the rocket downward at high speed. Under the reaction, the water rocket rises rapidly, with acceleration and inertia gl...

Problems solved by technology

[0004] However, most of the current water rockets have a short flight time, so they cannot continue to fly to a higher altitude and cannot meet the needs of students
