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

experiment example
[0087] The flight trajectory of the aircraft is simulated by the aircraft simulation system. In the simulation experiment, five 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.
[0088] In the first aircraft, the detachable composite range-extending system on the aircraft of the present invention is loaded, such as figure 1 As shown in , the aircraft is provided with a rocket range extender module, a bottom row extender module, a rolling range extender module and a gliding range extender module, and the above-mentioned range extender modules work together to maximize the range of the aircraft; the aircraft's Flight trajectory such as image 3 As shown in Scheme 1, it can hit a target 113 kilometers away when the fall speed is greater than 300 m / s, and ensure that the circular probability err...

The invention discloses a detachable composite range-extending system and method on an aircraft. The system 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. Cooperative work, in accordance with a predetermined sequence, work alternately in different flight stages, without interfering with each other, can increase the range of the aircraft, so that the final range of the aircraft can be improved to the greatest extent; Large storage space to fill the fuel, the rocket fuel tank will add more burden to the subsequent flight of the aircraft, so after the rocket engine work is completed, the rocket fuel tank and the tail of the aircraft where it is located are separated from the main body of the aircraft , thereby further increasing the range of the aircraft.
Description
technical field [0001] The invention relates to the field of aircraft control, in particular to a detachable compound range extender system and method on an aircraft. 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 aircraft when it hits the target, that is, r...
