Title:

STEALTH LARGE MANEUVERING TARGET AIRCRAFT AND CONTROL METHOD FOR STEALTH LARGE MANEUVERING TARGET AIRCRAFT

Document Type and Number:

WIPO Patent Application WO/2020/107846

Kind Code:

A1

Abstract:

A stealth large maneuvering target aircraft and a control method for the stealth large maneuvering target aircraft, which relate to the technical field of unmanned aircrafts, and solve the technical problems existing in the prior art in which the stealth characteristics of a target aircraft is poor and the comprehensive matching degree between the stealth design of the target aircraft and the flight performance is not high. The stealth large maneuvering target aircraft comprises a fuselage (100), machine wings (101), a vertical tail (102), horizontal tails (103), and a "clam-type" air intake channel (104) provided below a ventral of the fuselage (100). The machine wings (101) are provided at a middle part of the fuselage (100), which belongs to a lower single wing layout. The vertical tail (102) and the horizontal tails (103) are provided at a tail end of the fuselage (100). The present control method for the stealth large maneuvering target aircraft comprises: confirming a dynamic model has a high degree of accuracy and a high degree of confidence; employing overload and attitude combined control to ensure the stable control of a flight that has a large overload; and a control system using the overload, speed, angle of attack, and sideslip angle. The present stealth large maneuvering target aircraft may overcome the problem of poor stealth characteristics of an existing target aircraft, and may solve the problem in which the comprehensive matching degree between the stealth design of the target aircraft and the flight performance is not high.
