Simulated rocket multi-output experiment device

Abstract

A simulated rocket multi-output experiment device comprises a support, propellers and a simulated carrying cabin. The propellers and the simulated carrying cabin are arranged on the support; the propellers comprise distributed propellers; the plurality of distributed propellers are uniformly arranged on the outer side of the simulated carrying cabin, and each distributed propeller comprises a motor and a propeller arranged on the motor, or each distributed propeller is a turbojet engine; and guide plates capable of swinging are arranged at the bottoms of the distributed propellers. According to the simulated rocket multi-output experiment device, through the arrangement of the distributed propellers, the thrust and direction of the propellers can be accurately controlled by controlling therotating speed of the motors, adjusting the angles of the flow guide plates, swinging the directions of the propellers and other means, and the implementation effect is good; the simulated propellerby adopting the motors and the propellers is very close to the real stress state of a rocket, and is completely feasible for researching, demonstrating and verifying a multiple-input-multiple-output system.

Description

technical field [0001] The invention belongs to the technical field of scientific research and teaching appliances, in particular to a multi-output experimental device for simulating rockets. Background technique [0002] Accurate control of multiple outputs is a difficult problem in the field of control, and the rocket needs to control multiple components at the same time to complete the work of launch, flight, landing and recovery, which is a representative of multiple output systems and a good experimental research object. Most traditional simulated rockets use balloons, water guns, alcohol lamps and other similar devices to eject certain substances from the nozzles, thereby simulating the thrust generated by the rocket propeller to make the rocket rise. These traditional methods are acceptable for low-level introductory demonstrations, but because they cannot be quantitatively and accurately controlled, the implementation effect is poor, and the significance of education...
