Tethered aircraft, flight system including same, and control method thereof

Abstract

The invention relates to the field of unmanned aerial vehicles. Specifically, the invention relates to a tethered aircraft (10). The tethered aircraft comprises an aircraft body (11), at least one take-off and landing duct (12) arranged in the aircraft body (11), a lift rotor wing (14) located in the take-off and landing duct (12), at least one thrust duct (13) arranged in the aircraft body (11),and a thrust rotor wing (15) located in the thrust duct (13), wherein the aircraft body (11) has an integrally streamlined geometric design such that the left side portion of the aircraft body (11) forms a left fixed wing (18) and the right side portion of the aircraft body (11) forms a right fixed wing (19). The invention also relates to a flight system including the aircraft and to a control method for such the flight system. The aircraft disclosed by the invention can still take off, recover and stably follow up when the vehicle is in a high-speed running state, and has good cruising ability.

Description

technical field [0001] The invention relates to a tethered aircraft. The invention also relates to a flight system comprising such a tethered aircraft and a control method for such a flight system. Background technique [0002] UAVs based on vehicle flying wires are mainly used to follow vehicles or perform better vision detection. At present, such UAVs mainly adopt quadrotor design. However, it is difficult for quadrotor UAVs to cope with the conditions of vehicles traveling at high speeds, because neither their endurance, structural strength nor flight stability can support the following, flying and recovery of vehicles traveling at high speeds. , and there may even be a drone disintegration.
