<p>A pressure relief device (10) for preventing over pressurization of a propeller hub is disclosed. The pressure relief device is designed to fit within a ball hole opening (42) in the hub arm of the hub. The pressure relief device includes a housing (12) which sealably interfaces with an inner wall (44) of the ball loading hole opening and a diaphragm (32) which sealably interfaces with the housing. The diaphragm is designed to rupture at a design pressure thus venting the hub cavity.</p> |
