Embodiment 1

[0028] See attached figure 1 , a kind of flight test protective device of the present invention comprises:

[0029] A retractor 1 set on the ground, the retractor 1 includes a pre-tightening reel 4, a locking device 6, a controller 7 and a base 8; the base 8 is fixed on the ground, and the pre-tightening The reel 4 is supported on the base 8, and the locking device 6 is arranged on one side of the pre-tensioned reel 4 to lock or release the pre-tensioned reel 4. The locking device 6 be electrically connected with the controller 7;

[0030] The sensor 5 installed inside the retractor 1 is arranged at one end of the pre-tensioned reel 4 and is electrically connected with the controller 7;

[0031] Pulley block 2 fixed above the flight test area;

[0032] And the protection rope 3, one end of the protection rope 3 is connected to the pre-tensioned reel 4 in the retractor 1, and the other end is connected to the aircraft 9 around the pulley block 2.

[0033] The pre-tensioned ...

Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is: the sensor 5 is installed on the aircraft 9, the sensor 5 is connected with the controller 7 by radio, and the sensor 5 detects the speed, acceleration, Attitude angle, altitude and distance, when any one of these parameters exceeds the critical value set by the controller 7, the controller 7 enables the locking device 6 to be activated, and the aircraft 9 is suspended in the air.

[0048] A flight test protection method based on a flight test protection device, comprising the following steps:

[0049] Step 1: Fixedly connect the upper end of the aircraft 9 to one end of the protection rope 3;

[0050]Step 2: set the critical value of the speed, acceleration, attitude angle, height and distance of the aircraft 9 flying in the controller 7 according to the flight test situation;

[0051] Step 3: the aircraft 9 starts the flight test, detects the speed, acceleration, attitude angle, altitude and distance of the ...

Abstract

The invention discloses a flight test protection device and method, belongs to the technical field of aviation experiments, and aims at solving the problems of the prior art that the function is single and an aircraft flying in the air cannot be flexibly protected so as to avoid the crash accident of the aircraft. The flight test protection device comprises a retractor arranged on the ground, a sensor, a pulley group fixed above a flight test area and a protection rope, wherein the retractor comprises a pre-tightening winding reel, a locking device, a controller and a base; the base is fixed on the ground; the pre-tightening winding reel is supported on the base; the locking device locks or releases the pre-tightening winding reel and is electrically connected with the controller; the sensor can be mounted inside the retractor or on an aircraft and is connected with the controller through a wire or radio; and one end of the protection rope is connected with the pre-tightening winding reel in the retractor, and the other end bypasses the pulley group to be connected with the aircraft.

Description

technical field [0001] The invention belongs to the technical field of aviation test, and in particular relates to a flight test protection device and method. Background technique [0002] Compared with manned aircraft, unmanned aerial vehicles have lower development costs and higher use flexibility, can avoid personnel damage and complete specific tasks, and have more and more extensive applications in modern warfare, national economy, scientific research and other fields. The application has become a hot spot that companies and scientific research institutions around the world are competing to study. At present, there is an explosive trend of small unmanned aerial vehicles in the market. More and more unmanned aerial vehicles, especially multi-rotor aircraft, are emerging and widely used in aerial photography, inspection, agriculture, public security and other fields. [0003] A key content in the development and production of unmanned aerial vehicles is flight test, whic...
