Problems solved by technology

[0002] In recent years, as the speed of the aircraft becomes faster and faster, its aerodynamic shape tends to be flattened. The traditional wheeled horizontal landing device is not only difficult to arrange due to the size of the tires, but also its braking capacity is often insufficient (high speed will cause the temperature of the brake pads to If you want to continue to use the wheeled horizontal landing device, you must increase the braking device or increase the cooling system. Both methods will greatly increase the weight of the aircraft, and it is difficult to layout. The traditional wheeled horizontal landing buffer device It is difficult to meet the current demand

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0032] When a high-speed aircraft lands on various planetary surfaces, it needs to dissipate a large amount of energy in the horizontal and vertical directions at the same time. Especially when the aircraft is a manned or an aircraft equipped with precision instruments, it is necessary to adopt a buffer device to reduce the impact of landing. The impact force ensures the safety of personnel and the normal operation of precision instruments; the present invention arranges the horizontal landing buffer device in the front three points on the high-speed aircraft, wherein the landing buffer device is a wheelless type. The wheelless horizontal landing buffer device is composed of a skid structure, a skid buffer, and a foot pad. The cushioning device absorbs horizontal energy through foot pad friction on the runway, and the skid buffer absorbs vertical impact ...

Abstract

A wheelless horizontal landing device comprises a skid structure (1), a skid buffer (2), and a foot pad (3). The upper end of the skid structural member (1) is mounted on the aircraft body structure through a pin shaft, and the bottom end is connected with the foot pad (3) through the pin shaft; One end of the skid buffer (2) is connected with the skid structure (1) and the other end is connectedwith the landing gear of the aircraft; At that time of lan, the skid structure (1) is inclined, the skid buff (2) is cushioned, and braking is realized by relative friction between the foot pad (3) and the runway.

Description

technical field [0001] The invention belongs to the field of spacecraft structure and mechanism design, and relates to a wheelless horizontal landing buffer device. Background technique [0002] In recent years, as the speed of the aircraft becomes faster and faster, its aerodynamic shape tends to be flattened. The traditional wheeled horizontal landing device is not only difficult to arrange due to the size of the tires, but also its braking capacity is often insufficient (high speed will cause the temperature of the brake pads to If you want to continue to use the wheeled horizontal landing device, you must increase the braking device or increase the cooling system. Both methods will greatly increase the weight of the aircraft, and it is difficult to layout. The traditional wheeled horizontal landing buffer device It is difficult to meet the current demand. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies...
