Embodiment Construction

[0033] In order to make the implementation purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the embodiments of the present application.

[0034] In order to effectively evade missile threats by large aircraft and improve the survivability of large aircraft, the present application provides a method for avoiding attacks by large aircraft, which mainly includes an attack evasion process, a fuzzy inference rule establishment, and an aircraft terminal evasion process.

[0035] like figure 1 As shown, the attack evasion process in the method of the present application is as follows:

[0036] S1: Detect whether there are missiles in a certain area. The detection method can be detected by the detection equipment of the large aircraft itself, or detected by satellite means, or detected by drones, etc....

Abstract

The invention provides a method for avoiding an attack of a large aircraft. The method comprises the following steps: detecting whether there is no missile in a predetermined area; when there is a missile, judging whether a missile section target is a large aircraft or not; when no missile exists in the area or the target of the missile does not point to the large aircraft, the large aircraft normally executes a predetermined task; when the target of the guided missile section is a large aircraft, judging the coming direction of the guided missile, constructing a fuzzy inference rule according to the coming direction of the guided missile and the aircraft speed, and controlling the large aircraft to perform corresponding maneuvering actions by the aircraft according to the constructed fuzzy inference rule, or accelerating the flight of the large aircraft and getting rid of the guided missile by adopting an acceleration mode; then, whether the missile distance is smaller than a first preset value or not is judged, if yes, the large aircraft conducts diving S maneuver to avoid attacks, and if not, the original flight state is kept; then, whether the missile distance is smaller than a second preset value or not is judged, if yes, the large aircraft adopts tail-section avoidance, and if not, the large aircraft keeps the original flight state.

Description

technical field [0001] The present application belongs to the technical field of flight control, and particularly relates to a method for avoiding attacks on large aircraft. Background technique [0002] In modern air combat, air-to-air missile technology has emerged from scratch and has now become the main weapon in air combat, which has an important impact on air combat mode. Following the combat concept of "save yourself, shoot down the opponent, and gain air supremacy" in air combat, reasonable missile evasion is an essential homework in modern air combat. [0003] In recent years, scholars at home and abroad have conducted a lot of research on missile evasion strategies in air combat: Japanese scholars Imado and Miwa analyzed several maneuvering methods for fighter jets to avoid air-to-air missiles, and analyzed their applications for continuous maximum overload turning and linear acceleration maneuvers. Boundary conditions, the optimal maneuvering combination and mane...
