Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a guided flying object that receives reflected waves from a target and captures and tracks the target (-1). It is related to.

[Conventional technology]

FIG. 2 is a diagram simply showing a conventional guided flying vehicle.

In the figure, M is the guided missile, (11 is the target that the guided missile M captures and tracks, (2) is the reflected wave from the target (11), and (3) is the guided missile from the reflected wave (2). A guidance control device that steers the flight path of M toward the meeting point with the target (11), (4) provides a distance signal between the guided missile M and the target (11) when launching the guided missile M? The launcher (5) is a propulsion device that ignites and generates propulsive force when a launch signal is manually applied from the launcher (41).

The conventional guided spacecraft M is configured as described above, captures and tracks the target (11), flies to the meeting point with the target (11), and finally aims to meet with the target (11). There is.

[Problem that the invention seeks to solve]

In recent years, as the target has become faster and more maneuverable, the guidance flying body itself has become faster, so the steering drive force to drive the steering X needs to be larger than before, so the shape is mechanically larger. This is causing problems in the design of nine mechanisms. Furthermore, when the relative speed change is large, the steering control error becomes large, which deteriorates the guidance accuracy and impedes the shooting ability. Particularly in dogfights, where changes in relative speed are large and high maneuverability is required, and where the target is engaged immediately after launch, there is a problem in which the target is at high speed and has a high turning angle (in which case the guidance accuracy deteriorates and the ability to shoot down is affected). Ta.

This invention was made to solve these problems, and at the same time prevents the need for a larger steering driving force than before, it also prevents the deterioration of guidance accuracy in dogfights immediately after launching a guided projectile. The purpose is to prevent and improve shooting ability.

[Failure to solve the problem]

This invention is intended to achieve the above-mentioned objects, and at the same time prevents the need for a larger steering driving force than before, and at the same time improves the guidance accuracy in dogfights, a guided flying object is launched. A function is provided to control the propulsion force so that the speed and speed change of the guided spacecraft are within a range that is easy to guide and control from an arbitrarily set time before meeting the target.

[Effect]

In this invention, since the propulsion control device can maintain the speed and speed change of the launched control device within a predetermined range that is easy to control when meeting a target in a dogfight, the speed of the conventional guided projectile is Characteristic 9 Figure 3 is 9 Figure 4
The speed characteristics become as follows, and it is possible to eliminate unnecessary speed and speed changes in dogfight battles.

A propulsion force setting signal generator (8) is a propulsion force setting signal generator that generates a propulsion force setting signal to control the propulsion force so as to keep the guided spacecraft speed constant from the time before the specified time. This is a propulsion force control device that controls propulsion force using a propulsion force setting signal.

In the guided flight M1 configured as above, from the distance signal from the first launcher (4) to the target (1),
A target meeting time calculation section (6) measures the meeting time and outputs a meeting time signal. From the output meeting time signal,
The propulsion force setting signal generator (7) sets the optimum control amount and outputs the propulsion force setting signal, and the propulsion force control device (8) adjusts the propulsion force according to the propulsion force setting signal to the propulsion device (5). will be controlled.

〔Effect of the invention〕

This invention aims to reduce the size and weight of a guided missile by preventing deterioration of guidance accuracy immediately after launching a guided flying vehicle and by making it possible to steer a guided flying vehicle even with a steering drive unit with a small steering drive force. If the speed of the guided flying vehicle is high during the meeting, by reducing the speed of the control device, it is possible to follow the high-speed, high-mobility target in a dogfight even with a small steering drive force. It is expected that the system can be made smaller and lighter, and at the same time, the relative speed change can be reduced, resulting in improved guidance accuracy.
