Appl. No.:

13/864952

Inventors:

Honeywell International Inc. - , US
Jose Pagan - Luquillo PR, US
Ryan Goold - Glendale AZ, US

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

F16F 15/02
B64G 1/22
F16F 13/00

US Classification:

248562, 26714011

Abstract:

Embodiments of an isolator are provided, as are embodiments of a spacecraft isolation system employing a number of three parameter isolators. In one embodiment, the isolator includes a damper assembly and a thermal compensator external to the damper assembly. The damper assembly includes, in turn, a damper housing and a first hydraulic chamber, which is located within the damper housing and which is configured to contain a damping fluid. The thermal compensator includes a thermal compensator chamber, which is fluidly coupled to the first hydraulic chamber and which is configured to exchange damping fluid therewith during operation of the isolator. A thermal compensator bellows bounds an inner circumference of the thermal compensator chamber such that the bellows is externally pressurized when the first hydraulic chamber and the thermal compensator chamber are filled with the damping fluid.

Abstract:

Embodiments of an isolator are provided, as are embodiments of a spacecraft isolation system employing a number of three parameter isolators. In one embodiment, the isolator includes an externally-pressurized damper assembly and a thermal compensator, which is located external to the externally-pressurized damper assembly. The damper assembly includes, in turn, a damper assembly housing and a first hydraulic chamber configured to be filled with a damping fluid. The first hydraulic chamber is located within the damper assembly housing and is fluidly coupled to the thermal compensator. A first bellows is disposed within the damper assembly housing and bounds an inner circumference of the first hydraulic chamber such that the first bellows is externally pressurized when the first hydraulic chamber is filled with the damping fluid.
