Problems solved by technology

[0004] However, the proposed fixed fairing presents the additional problem of providing access to the brakes when the aircraft is stationary, for example for maintenance
In addition, in practice, there is usually a tow coupling or jacking point on the landing gear near the brake and the fixed fairing proposed by US Patent 2006 / 0102775 presents difficulties in accessing the towing or jacking point

Embodiment Construction

[0021] figure 1 A first embodiment of an aircraft landing gear according to the invention is schematically shown. landing gear included figure 1 The telescoping support legs 2 are shown in a fully extended state, showing the undercarriage before contact with the ground 4 and thus unloaded. The landing gear shown in this particular embodiment is an aircraft main landing gear having two pairs of tires 6 located at either end of a bogie beam 8 which is in turn pivotally connected to the lower end of a telescoping support leg 2 . Each wheel has associated therewith a brake 10, which is of a known design. The fairing 12 covers most of the front of the bogie beam and is wide enough to cover the forward brakes and the lower part of the bogie beam, including the jacking point 14 , while retaining clearance from the tires 6 . It should be understood that the wheels / tyres / brakes on the opposite side of the bogie beam to those shown are not included for clarity. The spinner 12 is piv...

Abstract

An aircraft landing gear including a fairing (12) arranged to be moveable between first and second configurations, wherein in the first configuration the fairing shields an element of the landing gear from an incident airflow, the fairing being arranged to be in the first configuration when the landing gear is deployed but unloaded, and wherein in the second configuration the fairing exposes the landing gear element to the incident airflow, the fairing being arranged to be in the second configuration when the landing gear is deployed and loaded.

Description

Background technique [0001] There is often a need to consider minimizing the noise produced by aircraft, for example to reduce the disturbance and inconvenience caused by aircraft noise to the public, especially near airports. The turbulent airflow created by aircraft landing gear creates a lot of noise during landing and takeoff. Also important to aircraft operators is the protection of the landing gear from damage caused by foreign object strikes. [0002] Attempts to address these problems have included mounting fixed air deflecting fairings to one or more components of the aircraft's landing gear. However, such fixed fairings have their own associated problems. Due to the complex geometry of the brakes, a significant portion of the noise generated by the landing gear is caused by the brakes. During landing, the brakes are usually applied immediately after the moment the aircraft touches down to help the aircraft slow down. While the application of the brakes tends to g...
