Embodiment Construction

[0033] figure 1 A schematic partial view of an aircraft landing gear 1 is shown. The landing gear 1 comprises a bogie beam 3 pivotally coupled to a slider 5 at a bogie pivot 7 . These aspects of the undercarriage 1 are conventional and are therefore not described in any detail here.

[0034] A mechanical position indicator 9 according to an embodiment of the invention is coupled to the bogie beam 3 . The position indicator 9 has a first state and a second state and is arranged to change from the first state to the second state when the bogie beam 3 assumes a predetermined position relative to the slider. The position indicator 9 is arranged such that it inhibits a transition from the second state back to the first state. Thus, the position indicator 9 provides an indication that the bogie beam 3 has assumed a predetermined position relative to the slider 5 . In some embodiments, this enables omission of stop pads (which are normally provided on the bogie beam 3 at location...

Abstract

A mechanical position indicator (9a) providing a visual indication that a first part of an aircraft landing gear (1) has assumed a predetermined position relative to a second part, the position indicator (9a) being arranged to be coupled to first and second The first of the two parts and in the first state is arranged to maintain the indicator element (15a) in the deployed position, the position indicator (9a) being arranged such that once the first part assumes a predetermined position relative to the second part, The second of the first and second parts changes the position indicator (9a) from a first state to a second state in which the indicator element (15a) is displaced from the deployed position, the position indicator (9a) being arranged to inhibit The indicator element (15a) then returns to the deployed position.

Description

technical field [0001] The invention relates to a mechanical position indicator and an aircraft landing gear comprising the same. Background technique [0002] It is known to use electronic sensors to provide an indication of the relative position between two parts of a piece of equipment. One example is an electronic proximity sensor arranged to determine when a bogie beam of an aircraft landing gear has assumed a predetermined position relative to the slider, thereby indicating that the aircraft has taken off. [0003] However, known sensors or indicators are difficult to interrogate by persons attempting to determine whether one part of equipment has assumed a predetermined position relative to another part of the equipment, especially after an event during a post-flight inspection of an aircraft landing gear. ask. Contents of the invention [0004] According to a first aspect of the present invention there is provided a position indicator providing a visual indicatio...
