Embedded electric drive course stability augmentation type skid landing device and working method thereof

Abstract

The invention discloses an embedded electric drive course stability augmentation type skid landing device and a working method thereof. The embedded electric drive course stability augmentation type skid landing device comprises an outer cylinder, an upper torsion arm, a lower torsion arm, a support, a skid, a guide wheel, an upper end cover, a piston rod, a rocker arm, a mounting plate, a friction plate, a load sensor, a buffer, a skid pitching buffer and an actuator cylinder module. The invention particularly provides an embedded electric drive course stability augmentation type skid landingdevice and a working method thereof. When the aircraft deviates in the sliding direction, the system controls the brushless motor to drive the rocker arm connecting rod mechanism to press the friction plate down the road surface to generate pressure, therefore, the binding force between the single-side landing device and the road surface is changed, the fuselage is subjected to yawing moment, sothat the skating direction of the aircraft is corrected, and the skating course stability of the aircraft is enhanced; the load sensor can measure the pressure of the friction plate on the road surface and provide feedback, the friction plate is made of a heat-resistant composite material, and specific lines are machined at the bottom of the friction plate, so that extra lateral force is provided,and the drifting phenomenon of the aircraft is reduced.

Description

technical field [0001] The invention relates to the technical field of hypersonic aircraft taxiing and landing, in particular to a skid landing device with built-in electric drive course stabilization and a working method thereof. Background technique [0002] Landing gear is mainly divided into wheeled landing gear and skid landing gear. Traditional aircraft mostly use wheeled landing gear, which is stable and easy to roll when landing, but there are problems such as complex structure, heavy weight, and large space occupation. The skid landing gear has the advantages of simple structure, light weight, low cost, reliable performance and small space occupation. For some hypersonic models, in order to reduce the design limitations of the landing gear on the retractable space and structural weight, a skid-type landing device is also used to decelerate and brake through the friction between the skid and the road surface. The X-15A of the United States used skid landing and cond...

AI Technical Summary

Problems solved by technology

However, for hypersonic vehicles that use skid landing gear to land, the traditional skid landing gear has problems such as unstable directions. Some of the patents for skid landing gear that have been published so far also have problems such as uncompact mechanisms, Poor heading stability and other problems, and most of them rely on the hydraulic system for actuation. Compared with the all-electric landing gear system that replaces the hydraulic system with an electric system, it has advantages in many aspects. The all-electric heading stability-enhancing skid landing device has greater research value
