Embodiment 1

[0036] like Figure 1~3 as shown, figure 1 It is a schematic diagram of the three-dimensional structure of a stealth large mobile target drone according to an embodiment of the present invention, figure 2 It is a front view of a stealth large mobile target drone according to an embodiment of the present invention, image 3 It is a side view of a stealth large maneuverable target drone according to an embodiment of the present invention. The stealth large maneuverable target drone provided by the present invention includes a fuselage 100, a wing 101, a vertical tail 102, a horizontal tail 103, and a machine mounted on the fuselage 100. The "clamshell" air intake 104 under the abdomen, the wings 101 are arranged in the middle of the fuselage 100, the wings 101 are located on both sides of the fuselage 100 and are symmetrically arranged, the vertical tail 102 and the horizontal tail 103 are arranged at the tail of the fuselage 100 .

Embodiment 2

[0046] On the basis of Embodiment 1, this embodiment further provides a control method for a stealth large maneuvering target drone to solve the problem in the prior art that the comprehensive matching degree between the stealth design and flight performance of the target drone is not high.

[0047] A control method for a stealth large mobile target drone provided by the present invention comprises the following steps:

[0048] S1: Confirm the dynamic model with high accuracy and high confidence through system identification;

[0049] S2: Combined overload and attitude control to ensure stable control flight with large overload;

[0050] S3: The control system uses overload, speed, angle of attack and sideslip angle to ensure the safety of overload and maneuvering flight.

[0051] In order to verify the feasibility of the large overload control scheme, it is verified through digital simulation, semi-physical simulation and turntable simulation. The control method of this stea...

Abstract

The invention provides an invisibility high-maneuvering target drone and a control method of the invisibility high-maneuvering target drone, and relates to the technical field of unmanned aerial vehicles. The technical problem that in the prior art, the target drone invisibility characteristic is poor, and the comprehensive matching degree of target drone invisibility design and flying performanceis poor is solved. The invisibility high-maneuvering target drone comprises an aircraft body, a wing, a vertical tail, a horizontal tail and a clam type air inlet way arranged below a belly of the aircraft body, the wing is arranged in the middle of the aircraft body and is arranged in lower single-wing layout, and the vertical tail and the horizontal tail are arranged on the tail of the aircraftbody. According to the control method of the invisibility high-maneuvering target drone, the high-accuracy high-confidence-coefficient dynamical model is affirmed, through overload and posture combined control, large-overload stable control flying is ensured, and a control system uses overload, speed, the attack angle and the side sliding angle. The problem that an existing target drone is poor in invisibility characteristic is solved, and the problem that the matching degree of target drone invisibility design and flying performance is poor is solved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a stealth large maneuverable target drone and a control method for the stealth large maneuverable target drone. Background technique [0002] The combat style of information warfare is transformed to "non-contact", so enhancing the stealth performance of UAVs has become an urgent problem for the military of all countries to solve. At present, the stealth technology of drones is still in the development stage, but with the continuous emergence of stealth materials suitable for fighter jets and the continuous improvement of stealth technology, the stealth performance of drones will be strengthened and improved. For combat aircraft, the most important stealth technology is radar stealth technology. Stealth has become an important indicator of the fourth-generation fighter jets. The American F-22 "Raptor" and the Russian S-37 "Golden Eagle" all have high stealth perf...
