Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0024] Such as figure 1 As shown, a method for automatic return and landing function verification, the specific steps are as follows:

[0025] ①Initial setting: take the compression of the landing gear as a symbol, and set the aircraft state to "ground state";

[0026] ②Initial position: Based on the landing point 2 of the aircraft, set the initial position of the aircraft at 4 points;

[0027] ③Movement: During the actual test, the aircraft will start from the initial position 4 of the aircraft and move northward to the radio positioning position 1;

[0028] ④Setting return altitude: set radio altitude, absolute barometric altitude and relative barometric altitude to about 500 meters return altitude;

[0029] ⑤ Positioning: Set the radio positioning position 1 on the radio navigatio...

Abstract

The present invention relates to the field of aircraft return verification, specifically a method for automatic return and landing function verification. The specific steps are as follows: ① initial setting; ② initial position; ③ movement; ④ setting return height; ⑤ positioning; ⑥ setting Parameter; 7. setting; 8. correction; 9. sailing; adopt the present invention to carry out experimental verification, have utilized the characteristic that the radio navigation positioning accuracy of integrated navigation system is high and can correct the position of inertial navigation, by setting radio positioning position and inertial navigation The position difference method, the radio position corrects the position of the inertial navigation, omits the flight simulation software, and reduces the cost; the test is carried out by simulating the air flight process through the position correction, which simplifies the test and facilitates the ground operation.

Description

technical field [0001] The invention relates to the field of aircraft return verification, in particular to a method for automatic return and landing function verification. Background technique [0002] Modern aircraft generally have automatic return and automatic landing functions, and when conditions permit after automatic return, they can automatically change from the return state to the landing state. However, in the test verification, the following two methods are generally used: one is to check the automatic return function and the automatic landing function separately, and the connection function is not tested, and it is verified by the air flight test; the other is to simulate the air flight process by establishing flight simulation software. test. The first method needs to carry out air tests, the test process is complicated, and it is not real-time. The second method requires high fidelity of flight simulation software, requires a large initial investment, is comp...
