Method for controlling rollover, yaw and yaw stability of aircraft

Abstract

The invention relates to a system for controlling rollover, yaw and yaw stability of an aircraft. The system comprises a yaw and rollover stabilizer composed of an upper yaw and rollover stabilizer and a lower yaw and rollover stabilizer, wherein the bottom end of the upper yaw and rollover stabilizer and the top end of the lower yaw and rollover stabilizer are respectively rotatably connected with upper and lower symmetrical surfaces of the aircraft at the tail end of the aircraft and can independently rotate around a shaft in an up-down direction, the upper yaw and rollover stabilizer is arranged above the mass center of an airplane, and the lower yaw and rollover stabilizer is arranged below the mass center of the airplane; and the two yaw and rollover stabilizers are the same or similar in size and shape. The system provided by the invention is arranged on a center line of an aircraft provided with a pull-type nose propeller, so that the system fully utilizes slipstream produced by an aero-propeller, and effective rollover and yaw control can be produced even during low speed flight and hovering.

Description

technical field [0001] The invention relates to a control system for rollover, yaw and yaw stability of an aircraft, and belongs to the technical field of aircraft control systems. Background technique [0002] Since the time of the Wright Brothers, rotatable control surfaces have been used as aircraft control systems. The elevator and rudder used on the earliest aircraft controlled the aircraft's pitch and yaw / roll respectively. These planes were slow to roll and turn. Invented by the Wright Brothers, the warping wing enabled for the first time independent three-axis control of an aircraft, increased rollover rate, and reduced turning radius. Later, Glenn Curtis invented the aircraft aileron to control rollover, which is a great invention with significant simplification and improvement compared with warping wings. [0003] Since then, someone has invented the elevator stabilizer (stabilator), which is a control system that combines the stabilization function of the horiz...

Problems solved by technology

[0005] The rudder and vertical full tail have traditionally not been a significant contributor to roll control because the vertical tail has traditionally been much shorter than the wings, too short a moment arm for effective roll control

For newer airframe designs, including low-aspect-ratio fixed-wing VTOL aircraft, the roll inertia and aerodynamic drag to inhibit roll are very low, making it possible for the vertical tail surface to act as the primary roll control, but this A technique that has never been practiced
