Purpose & Scientific Principle
The content of Newton's third law is that the action and reaction forces between two objects are always equal in magnitude, opposite in direction, and act on the same straight line. According to Newton's third law: forces act reciprocally, so the air will also give an upward reaction force to the blades. This reaction force is lift. When the lift force is greater than the helicopter's own gravity, the helicopter will fly into the air.
How to Operate
This exhibition mainly consists of operating handwheel, transmission mechanism, helicopter model, protective cover, exhibition stand, etc. The exhibition stand is equipped with an operating hand wheel, and a transmission mechanism and a helicopter model are installed in the protective cover. When the audience turns the handwheel, the transmission mechanism drives the propeller to rotate. When the handwheel reaches a certain speed, the helicopter rises vertically.
Turn the handwheel and watch the helicopter rise vertically.
