Problems solved by technology

[0002] The traditional rotary-guided aircraft cannot automatically calibrate the target point after launch, and the internal system of the aircraft is also relatively complex. At the same time, the control strategy of the rotary-guided aircraft in the gliding section does not fully utilize the steering gear resources, that is, the rotation-guided aircraft does not give full play to due potential to increase range
In the prior art, although there are some methods for increasing the range of the rotary guidance aircraft, a simple range-extending technology can no longer meet the requirements of long-distance flight of the aircraft

Embodiment

[0083] Select a set aircraft (such as guided shells), load the bottom row system, rocket booster system and two-loop speed and direction control system on the aircraft, and the two-loop speed and direction control system includes a damping loop module, navigation module I, and central control system. Module I and Execution Module.

[0084] Among them, the damping loop module uses the angular velocity gyro DLA141 (AD sampling accuracy is 12 bits, the main frequency is 18Mhz, the power supply is 10-12V, and the output amplitude is 12V). The speed is measured to realize three-dimensional positioning and navigation; the horizontal two-dimensional position error is less than 12 meters, and the position accuracy in the elevation direction is less than 15 meters; the northeast sky direction speed error is less than 0.5 m / s), and the central control module I uses the DSP microprocessor of TI company TMS320F28355 (system clock up to 150MHz; built-in 256kⅹ16-bit flash; built-in 16-chann...

Abstract

The invention provides a rotating guidance aircraft's extended range system and the method. The extended range system comprises a bottom row system, a rocket propelling system, and a speed direction control system wherein the speed direction control system is used to control the aircraft to slide towards a targeted area at a track inclined angle theta 0 from a sliding section on a flight track. The speed direction control system controls all steering engines of the aircraft to steer alternately on a gliding section and provides climbing force to the aircraft so as to maintain the fixed track inclined angle and to make up the shortcomings of a traditional aircraft of a lack of climbing force. Through the composite use of a bottom row system, a rocket propelling system and a speed direction control system, the range of a manufactured aircraft is greatly increased; the application areas of the manufactured aircraft are also expanded. Therefore, the system and method are of great practical values.

Description

technical field [0001] The invention relates to the field of guided aircraft, in particular to a range-extending system and method for a rotary guided aircraft. Background technique [0002] The traditional rotary-guided aircraft cannot automatically calibrate the target point after launch, and the internal system of the aircraft is also relatively complicated. At the same time, the control strategy of the rotary-guided aircraft in the gliding section does not fully utilize the steering gear resources, that is, it does not give full play to the rotation-guided aircraft. Due potential to increase range. In the prior art, although there are some methods for increasing the range of the rotary guidance aircraft, a simple range-extending technology can no longer meet the requirements of long-distance flight of the aircraft. Therefore, it is an urgent problem to be solved to maximize the advantages of multiple range-extending methods by adopting an airborne speed-direction contro...
