Embodiment Construction

[0031] The disclosure is capable of embodiments in different forms, the drawings illustrate and embodiments of which will be described in detail herein, but it is to be understood that the description is to be considered as an illustration of the principles of the disclosure and is not intended to be exhaustive or to limit the disclosure. Details of the construction and arrangement of the components described and shown in the drawings are described below.

[0032] Such as figure 1 As shown, an aircraft jet engine 12 is generally surrounded by a large cylindrical structure 14 which generally includes one or a pair of aircraft panels or nacelles 16 and 18 . Aircraft engine cowls 16 and 18 are typically mounted by hinges 20 to an engine support structure 22 , such as where an engine can be mounted to the aircraft via an engine pylon. Hoods 16 and 18 are hinged such that they can pivot to provide maintenance and repair access to engine 12 . During aircraft operation, the cowls 1...

Abstract

A damping device using viscous shear to moderate substantially linear movement. The device has a housing with one or more reservoirs containing a viscous fluid, such as silicone, and one or more retractable struts that can extend from the housing. The strut has a portion formed as a toothed rack, and an associated axle has a pinion gear on a portion associated with the toothed rack of the strut. The teeth of the rack mate with teeth of the pinion gear. A disk, or preferably series of spaced disks, can be mounted on the axle inside the reservoir to dampen linear movement of the strut, from shear with a static plate adjacent to the disk on the axle. The relatively fixed, spaced disks or plates are adjacent to or interdigitated with the disks on the gear axles to dampen linear movement of a strut.

Description

technical field [0001] The present disclosure relates to viscous shear damping strut assemblies, and more particularly, to damping devices having interacting discs for viscous shear damping strut assemblies in a predominantly linear direction. Background technique [0002] Although the field of use is not limited, the damping device may be used with aircraft systems. Certain aircraft systems are used with aircraft jet engines, usually surrounded by a nacelle, a large cylindrical structure that typically includes one or a pair of pivoting aircraft nacelles. Aircraft engine cowls are typically hingedly mounted to the engine support structure. Latching mechanisms have been used to releasably secure a first aircraft structure, such as an aircraft panel or cowling of an aircraft engine, to another aircraft structure. [0003] Aircraft systems must withstand harsh environments. Aircraft systems must withstand high vibrations and extreme temperature and pressure ranges. For exa...
