Embodiment Construction

[0017] Front landing gear design of the present invention has adopted simple prop type, single-wheel landing gear (see figure 1 ). Equipped with an automatic wheel centering device, when the landing gear buffer strut is fully extended, the wheel will automatically return to the neutral position. In addition, in order to prevent the front wheel from shaking, a shock absorber is installed on the front landing gear, and square-section tires that are conducive to anti-swing are used.

[0018] The retraction and retraction of the landing gear is completed by the retractable actuator 2 controlled by the hydraulic system, the retractable actuator piston rod 3 shortens the landing gear and retracts into the fuselage; the retractable actuator piston rod 3 stretches out the landing gear and puts it down , Mechanical locks are designed at both ends of the strut actuator to lock the landing gear when the landing gear is retracted or lowered.

[0019] The front landing gear mainly has th...

Abstract

The invention belongs to the field of aircraft engineering, and provides a nose landing gear of an aircraft. The nose landing gear is arranged on an aircraft structure through two mounting shafts on a buffer support column, and can rotate around the mounting shafts; one end of a stay bar folding and release actuating cylinder is provided with a joint bearing; the joint bearing is connected with a shaft of the buffer support column and is fixed by a nut; the other end of the stay bar folding and release actuating cylinder is arranged on a body structure joint through a threaded shaft; a wheel fork is arranged on an inner cylinder of the buffer support column through a bolt; a wheel and a tire are arranged on the wheel fork by using a wheel shaft; the upper end of an upper anti-twist arm is arranged on an annular body joint; the lower end of a lower anti-twist arm is arranged on a joint of the wheel fork.; the upper anti-twist arm and the lower anti-twist arm are connected by a quick-release pin. The nose landing gear has a simple structure and complete functions on the premise of guaranteeing the strength and the rigidity of the landing gear, and is suitable for small-sized aircrafts.

Description

technical field [0001] The invention belongs to the field of aeronautical engineering and relates to an aircraft nose landing gear. Background technique [0002] Although the landing gear of modern aircraft is various, the landing gear that is suitable for small aircraft is rare. With the rapid development of small aircraft, especially unmanned aerial vehicles, the demand for a landing gear suitable for small aircraft and with complete functions is particularly urgent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a retractable aircraft nose landing gear that can meet the requirements of small aircraft and unmanned aerial vehicles. Under the premise of ensuring the strength and rigidity of the landing gear, the landing gear should be simple in structure and complete in function , and make its structure lightest. [0004] Technical scheme of the present invention: a kind of aircraft front landing gear, compris...
