Problems solved by technology

This solution is susceptible to water resistance and turbulence, is very costly and requires a very good seal during the test
The free fall method is to make the test target do flat throwing motion on the plane or in a near-vacuum drop tower (such as the famous Bremen drop tower in Germany), and its disadvantages are high cost and short test time

Embodiment 2

[0016] according to figure 1 , figure 2 , the working principle of the present invention is such: at first assume that aircraft is subjected to the effect of a force passing through the center of mass of the aircraft in three-dimensional space. Force can be equivalently decomposed into horizontal component and vertical component in three-dimensional space. The horizontal component of the force pulls the trolley to move in the horizontal direction, because there is approximately no friction between the air-floating guide rail and the trolley, so the approximately friction-free movement of the aircraft in the horizontal direction is realized by means of the air-floating guide rail; the vertical force of the force The component changes the feedback value of the force sensor that senses the pulling force of the hanging wire, thereby controlling the drive motor to make a corresponding response according to a predetermined control rule to ensure that the tension of the hanging wir...

Embodiment 3

[0018] to combine figure 2 , image 3 , the structural design of the weightlessness simulation control system can be as follows figure 2 As shown, the weightlessness simulation control system 6 is composed of a motor 7 , a winding wheel 8 , a hanging wire 9 , and a force sensor 10 . The motor 7 is connected to the wire winding wheel 8 , the wire winding wheel 8 is connected to the hanging wire 9 , the hanging wire 9 is connected to the force sensor 10 , and the sensor 10 is connected to the aircraft 11 .

[0019] The working process of the weightlessness simulation control system is as follows: the control command of the servo motor comes from the controller placed on the pulley. When the tension of the hanging wire changes, the feedback value of the force sensor that senses the pulling force of the hanging wire changes, and the controller calculates the control command through the feedback value of the force sensor. The input signal of the controller is the feedback value...
