Abstract: The capacity of airliner overhead storage bins is increased by replacing the original door with a curved replacement door. The replacement door has an outwardly curved main panel, and at least one side panel that fills the space between the main panel of the door and the bulkhead of the storage bin.

Abstract: A cam mechanism enabling the pilot to automatically advance the propeller low pitch stop with the engine power lever on airplanes with multibladed propeller systems having a beta control mechanism for adjusting the blade angle. The cam provides an inexpensive and reliable alternative to costly and complex automatic feathering systems.

Abstract: An air inlet assembly for a gas turbine aircraft engine includes a fixed turning vane and a movable turning vane that is carried on the trailing edge of the air deflector door. To optimally direct and accelerate a flow of air into the engine intake, the low-pressure and high-pressure surfaces of the airfoil-shaped fixed turning vane lie in parallel planes at the trailing edge of the vane. The turning vane on the air deflector door has a low-pressure, convex surface that rests against the fixed turning vane when the door is deployed in the anti-icing mode. Under normal conditions, the door is stored and the two vanes cooperate to form an aerodynamic converging channel, which accelerates the flow and attaches it to the low-pressure surface of the vane on the door.
