ABSTRACT:

TECHNICAL FIELD
This invention relates to pressure vessels and more particularly to a mounting assembly for mounting composite pressure vessels to structures.
BACKGROUND OF THE INVENTION
In many aircraft and spacecraft the flight control surface, (flaps), are positioned by pneumatic actuators. A pneumatic actuator is an actuator that is operates by high pressure gas. The high pressure gas is commonly stored in steel bottles that are directly bolted to some structure on the aircraft or spacecraft. A disadvantage to using these steel vessels is their weight.
Because keeping the weight of the spacecraft as low as possible is a critical design goal, it has been proposed to replace the steel vessels with composite vessel that weighs substantially less. A problem with using composite vessels is that it is difficult to make such vessels with lugs or other integral attachment devices.
Accordingly, a need exists for a mounting assembly for mounting a composite bottle or pressure vessel to a structure. The assembly must be able to accommodate the expansion and contraction of the vessel as it fills and empties.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a mounting assembly for mounting a composite pressure vessel to a structure.
Another object of the present invention is to provide a mounting assembly for mounting a composite pressure vessel to a structure that accommodates the expansion and contraction of the vessel as it fills and empties.
The present invention meets these objects by providing a mounting assembly for a composite pressure vessel comprising a saddle having a curved surface extending between two pillars for receiving the vessel. The saddle also has flanged portions which can be bolted to the vehicle. Each of the pillars has hole in which is mounted the shaft portion of a attachment member. A resilient member is disposed between each of the shaft portions and the holes and loaded by a tightening nut. External to the holes, each of the attachment members has a head portion to which a steel band is attached. The steel band circumscribes the vessel and translates the load on the resilient members into a clamping force on the vessel. As the vessel expands and contracts, the resilient members expand and contract so that the clamping force applied by the band does not significantly change
These and other objects, features and advantages of the present invention are specifically set forth in or will become apparent from the following detailed description of a preferred embodiment of the invention when read in conjunction with the accompanying drawings.
