Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with specific examples and accompanying drawings.

[0038] Such as figure 1 As shown, the present invention is applicable to an online no-fly zone avoidance guidance method for aircraft, and its steps are as follows:

[0039] Step 1. Obtain the specific latitude and longitude of the center of the effective no-fly zone in front of the aircraft and the threat radius through the detection system of the aircraft or the ground information receiving system, and obtain the position and size of the effective no-fly zone. Known technology in the field.

[0040] Step 2: Further analyze the distribution of the effective no-fly circles, merge multiple no-fly circles that overlap, or the distance between the no-fly circles is relatively close, and the aircraft cannot pass through the middle at all into one no-fly circle, and re-determine The center position and radius of the newly generated no-fly circle. The ...

Abstract

The present invention provides an online no-fly zone evasion guidance method suitable for aircraft. The steps are as follows: 1. Determine the position, size and number of effective no-fly zones in front of the aircraft; Merge to obtain the final effective no-fly zone position and size; 3. Determine the virtual waypoint sequence to avoid the no-fly zone according to the existing path planning and decision-making methods; 4. Calculate the guidance coefficient of the improved proportional guidance method; 5. , calculate the size of the lateral force required by the aircraft; 6. track the longitudinal profile by adjusting the angle of attack vertically, and obtain the size of the force required in the longitudinal direction; Method; the guiding method described in the present invention is scientific, good in manufacturability, and has wide popularization and application value.

Description

Technical field: [0001] The present invention provides a kind of guidance method applicable to aircraft online no-fly zone evasion, it relates to a kind of guidance method that needs to avoid no-fly zone in the process, more particularly, refers to the guidance method applicable to aircraft no-fly zone avoidance, It belongs to the technical field of aircraft guidance. Background technique: [0002] Aircraft is a type of aircraft that flies at supersonic speed and flies in near space most of the time, and its flight altitude is between that of aerospace vehicles and aerospace vehicles. In recent years, the development of aircraft is getting faster and faster, which has the characteristics of high speed and long flight distance. The gliding segment is a very important stage in the flight process. At this stage, the aircraft decelerates and descends, and consumes excess energy. [0003] With the in-depth development of aircraft, the design of guidance laws has been paid more ...
