Variable-duct tailstock type high-speed unmanned aerial vehicle and working method thereof

Abstract

The invention discloses a variable-duct tailstock type high-speed unmanned aerial vehicle and a working method thereof. The unmanned aerial vehicle comprises a fuselage, canards, sweepback wings, rotor systems, sweepforward wings, ailerons, a wing vertical undercarriage, a lower half duct, a rear undercarriage, a vertical fin, a rudder, a vertical fin vertical undercarriage, a front undercarriage, a duct telescopic mechanism and an upper half duct. When the unmanned aerial vehicle is in a tailstock type aircraft mode, the upper half duct does not retract into the lower half duct, namely, the unmanned aerial vehicle is in a full duct form; when the upper half duct shrinks into the lower half duct, the duct is changed into a half duct form from a full duct form; free switching between a vertical flight mode and a fixed-wing aircraft mode is achieved, meanwhile, the advantages that a tailstock type unmanned aerial vehicle can take off and land vertically and is small in parking area are achieved, the design that a whole duct is changed into a half duct enables the duct to change the mode according to the flight requirement in the whole flight process, and the inherent problem of lifting force waste after tilting of the duct is solved.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and specifically refers to a variable duct tailstock type high-speed unmanned aerial vehicle and its working method. Background technique [0002] The tail seat unmanned aerial vehicle is a new type of aircraft that takes into account the advantages of both fixed-wing and rotary-wing aircraft. Its design concept can be traced back to the end of World War II. At that time, this innovative aircraft still remained in theoretical research. , has not been verified and put into production, but after that, this new concept aircraft has attracted more and more attention from countries all over the world. As a tail seat configuration aircraft that can realize high-speed flight and vertical take-off and landing at the same time, the research progress and attention paid are far inferior to those of compound helicopters and tilt rotor aircraft. However, the existing tailseat UAVs in my country adopt ...

AI Technical Summary

Problems solved by technology

However, the existing tailseat UAVs in my country adopt the fixed-wing aircraft configuration, and a large-radius rotor is installed at the front end of the nose. At the same time, in order to balance the reverse torque, the coaxial rotor has to be used, which undoubtedly reduces the parking area. advantage, and the center of gravity of the aircraft in this configuration is more upward when taking off and landing vertically, and the stability is not strong enough
