Problems solved by technology

However, during the ground run of the aircraft, the traditional skid-type landing gear can provide very little lateral force. For a skid-type aircraft with a certain landing horizontal initial velocity, once it is subjected to crosswind, initial yaw angle, runway The interference of equal and asymmetric factors, because the ground lateral force used for deflection correction is insufficient, the deflection correction effect of the skid is poor, and the aircraft is easy to rush out of the runway, causing serious accidents

Abstract

The invention discloses a retractable skid-type landing device with auxiliary wheels suitable for narrow spaces. The landing device is divided into a skid retractable module and an auxiliary wheel retractable module; Moving barrel, main buffer, first side strut, second side strut, upper torsion arm, lower torsion arm, skid and pitching buffer; auxiliary wheel retractable module includes first to eighth auxiliary wheels, first to the fourth connecting rod, the first to the second connecting shaft, the first to the second bearing, the first to the second connecting shaft lifting cylinder, the first to the fourth steel cable, the first to the fourth fixed pulley, the first One to the fourth auxiliary wheel retractable cylinder and support. The invention adds a plurality of small auxiliary wheels to improve the landing device for correcting the lateral force, and improves the ability of the aircraft to roll and correct the deviation on the ground; and compared with the original skid landing device, the space occupied by the fuselage is not greatly increased.

Description

technical field [0001] The invention relates to the technical field of aircraft taxiing and landing, in particular to a deflection-correctable skid-type landing device with auxiliary wheels, which is suitable for narrow retractable spaces. 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. The tires can provide large lateral force and have good stability in the rolling direction. However, the wheeled landing gear has problems such as complex structure, heavy weight, and large volume, and has relatively high requirements on the road conditions of the landing road. The skid landing gear has simple structure, light weight, low cost, reliable performance, and is not easy to be damaged. Due to the limitations of the device's retractable space and structural weight, some hypersonic models with large wheels cannot be used. ...
