Problems solved by technology

However, in the prior art, although there are some methods to increase the range of the aircraft, such as boosting the rocket engine to further increase the altitude and speed, such as increasing the air temperature at the tail of the aircraft through the bottom row method to reduce the drag, etc., these methods have not been coordinated. , failed to concentrate in the same aircraft; there are other solutions to adjust the gliding angle of the gliding section, but excessive adjustment of the gliding angle will reduce the speed value of the aircraft when it hits the target, that is, reduce the falling speed, so many times it has to be discarded. Range-extending scheme; In addition, the range-extending effect in the existing technology still cannot meet the increasing demand for high range, and it is necessary to consider designing more and better range-extending schemes
[0003] In addition, with the gradual increase of the range of the aircraft, the area the aircraft can pass through increases, and the possibility of being interfered by terrain, weather and various other signals is higher, especially in some harsh environments. The satellite signal receiver cannot receive the satellite signal. When the satellite is lost, the aircraft will lose control. For the long-range aircraft, the guidance section is longer, and the side effects caused by the satellite loss will be more serious. In the end, it is often difficult to make up for the amount of sideways through correction, that is, the target cannot be hit

experiment example

[0161] The flight trajectory of the aircraft is simulated by the aircraft simulation system. In the simulation experiment, seven aircraft of the same type are launched in the same direction at the same launch site. The farthest target that can be hit under the condition of speed constraint, wherein, in this test, the fall speed constraint is greater than 300 m / s.

[0162] The first aircraft is the compound range-extending aircraft described in the present invention that can be applied to areas where satellite signals are unstable, such as figure 1 As shown in , the aircraft is equipped with a rocket range extender module, a bottom row extender module, a roll extender module, a gliding range extender module and a processor module for calculating the required overload, and the above modules work together to maximize improve the range of the aircraft; the flight trajectory of the aircraft is as follows Figure 5 As shown in Scheme 1, it can hit a target 113 kilometers away when ...

Abstract

The invention discloses a compound range-extending aircraft that can be applied to areas where satellite signals are unstable. The aircraft is simultaneously equipped with a rocket range-extending module, a bottom row extending-range module, a rolling-range extending module and a gliding range-extending module. Each module They work together, and work alternately in different flight stages according to a predetermined order, without interfering with each other, which can improve the range of the aircraft, so that the final range of the aircraft can be improved to the greatest extent; in addition, a processor is also set on the aircraft module and the quasi-satellite guidance calculation module, the quasi-satellite guidance calculation module is used to provide the processor module with the aircraft position and speed information at the current moment required for calculating the overload required when the star is lost, so that the aircraft It can still navigate and guide normally without losing control.

Description

technical field [0001] The invention relates to the field of guidance and control aircraft, in particular to a compound range-extending aircraft that can be applied to areas where satellite signals are unstable. Background technique [0002] Modern battlefields put forward higher requirements for the range of guided aircraft. Increasing the range can improve the survival probability of combatants and generate richer strategies and tactics. However, in the prior art, although there are some methods to increase the range of the aircraft, such as boosting the rocket engine to further increase the altitude and speed, such as increasing the air temperature at the tail of the aircraft through the bottom row method to reduce the drag, etc., these methods have not been coordinated. , failed to concentrate in the same aircraft; there are other solutions to adjust the gliding angle of the gliding section, but excessive adjustment of the gliding angle will reduce the speed value of the...
