A roll control mechanism suitable for small vertical take-off and landing fixed-wing aircraft

Abstract

The invention discloses a rolling control mechanism suitable for a small vertical take-off and landing fixed-wing aircraft, comprising a rolling nozzle and a rolling control adjusting mechanism. , a rolling nozzle is installed symmetrically to the left and right along the radial direction of the engine barrel, and the rolling control and adjustment mechanism includes a driving device installed on the outer wall of the engine barrel and a rolling nozzle installed inside the connection between the rolling nozzle and the engine barrel. The blocking device, the driving device drives the blocking device to adjust the size of the airflow inlet of the rolling nozzle; the invention has a simple and delicate structure, light weight, the rolling nozzle can be quickly installed and unloaded, and the rolling control and adjustment mechanism has high maintenance accessibility. , By controlling the steering gear, it can provide partial lift for the aircraft in the horizontal flight state and the vertical take-off and landing state, and realize the roll control of the acceleration transition from the vertical take-off and landing state to the horizontal flight state.

Description

technical field [0001] The invention belongs to the technical field of aeronautical aircraft design, in particular to a roll control mechanism suitable for small vertical take-off and landing fixed-wing aircraft. Background technique [0002] The vertical take-off and landing fixed-wing aircraft not only has the ability of the rotorcraft to take off and land vertically and control the hovering, but also has the advantages of fast speed and long range of the fixed-wing aircraft. It is a research hotspot in recent years. The rolling nozzle is an important part of the VTOL fixed-wing aircraft. It can provide partial lift for the aircraft in level flight and VTOL state, and provide rolling torque for the aircraft during the acceleration transition from the VTOL state to the level flight state. Play the role of adjusting posture. At present, the rolling nozzles of large vertical take-off and landing aircraft generally use double-door nozzle nozzles. The opening and closing degre...

AI Technical Summary

Problems solved by technology

At present, the rolling nozzles of large vertical take-off and landing aircraft generally adopt double-door nozzle nozzles, and the opening and closing of the two doors are controlled by two actuators, and the aircraft is controlled by adjusting the flow and speed of the airflow. Its structure is complex, heavy, difficult to maintain, and not suitable for small vertical take-off and landing fixed-wing aircraft
