In the step 2, the controller starts the second power source to wind the connecting rope while starting the first fans, the lower safety net is tensioned, the circumferential edge of the lower safety net is close to the inner wall of the wind tunnel body and used for ensuring the safety of the parachute jumping personnel, after the controller receives a parachute opening signal of the parachute opening monitoring device or a parachute opening signal sent by field personnel through the handheld terminal, the controller controls the second power source to release the connecting rope at a specified time, and the connecting rope and the lower safety net fall into the bottom of the wind tunnel body under the action of gravity, so that the bottom of the wind tunnel simulates a hard ground landing environment.

And 2, taking the parachute jumping personnel to simulate the plane parachute jumping cabin, controlling the pitching, the jolting and/or the heeling of the plane model by the controller through the stretching of the third power source in the ascending process of the lifting device, simulating the flight state of the plane, creating a vivid plane flight environment, and enabling the parachute jumping personnel to go out of the cabin door to pass through the connecting channel to enter the parachute jumping position when the lifting device reaches the parachute jumping position at the top of the wind tunnel body.

The method for performing parachuting training by using the parachuting training equipment fills the blank of ground parachute opening training, can simulate the whole process of real high-altitude parachuting indoors in a very vivid way, and has the advantages of good using effect, low cost, high efficiency, safety and reliability.
