An engine mounting configuration reacts engine thrust at an aft mount. The engine mounting configuration reduces backbone bending of the engine, intermediate case distortion and frees-up space within the core nacelle.

A fail-safe lug is carried by an engine frame member and receives a clevis carried by an engine mount member. The mount member includes side links that transmit transverse loads between the engines and the airframe and a thrust link that transmits axial, engine thrust loads between the engine and the airframe. A fail-safe pin is carried by the clevis and has an outer diameter that is smaller than an aperture in the lug and through which the pin passes, so that no loads are imposed on the fail-safe pin in normal operation. When one or more of the links are no longer capable of transmitting loads, the fail-safe arrangement becomes operative to accommodate the loads transmitted between the engine and the airframe.

The invention provides rear suspension structures and engine cradles involving tubular components. The tubular components have variable wall thickness along the length for reducing materials required. The tubular components also have mechanical properties varying along the length of the tubular components, to meet the requirements on strength and dynamic and static loads. The weight of the tubular components can be further reduced by appropriately varying the wall thickness and mechanical properties along the length of the tubular components.

A hybrid electric vehicle contains a powerplant for propelling the vehicle. The powerplant comprises a combustion engine (6) and a dynamoelectric machine (8). A control system (10) issues a wheel torque command corresponding to torque desired at road-engaging wheels, and includes an engine controller (16) for issuing an engine torque command and a dynamoelectric machine controller (18) for issuing a dynamoelectric machine torque command. Controller (18) contains one or more maps and/or profiles defining functional relationship of torque to engine crankshaft speed and/or position over a range of crankshaft speeds and/or positions. The maps and/or profiles are used to develop make-up torque that is delivered by the dynamoelectric machine to accomplish certain smoothing functions. Transmission gear shifts can be smoothed by using the dynamoelectric machine controller to slew the engine to a new target speed appropriate to the new gear. A dedicated, high-speed data communication link supplies crankshaft speed and position information from an engine-mounted sensor directly to controller (18).

In a starter for starting an on-vehicle engine, a solenoid is provided to push a pinion gear. The solenoid has an electromagnetic coil composed of a single coil and electrically separated from a motor circuit, a fixed core, and a plunger. Supply of excitation current to the electromagnetic coil allows the fixed core to be magnetized to attract the plunger. Hence, a movement of the plunger results in a push of the movable member toward the ring gear. A switch is provided in the circuit and has a contact, a movable core, and a switch coil functioning as an electromagnet attracting the movable core in response to supply of current to the switch coil. A movement of the movable core results in on/off switching operations of the switch. The switch is allowed to operate independently of the solenoid when both the switch and solenoid are controlled.

A projection display is provided according to one embodiment of the invention. The projection display includes a hollow case including a window opening, a screen formed on one portion of the case, and at least one mirror internally mounted to the case at a position to reflect light from the window opening to the screen. The projection display further includes a window mounted in the window opening. The projection display further includes an optical engine mounted to the case. The optical engine is positioned over the window and oriented so that emitted light from the optical engine is directed onto the at least one mirror. The projection display further includes a diaphragm internally attached to the case and dividing an internal volume of the case into a first portion and a second portion. The projection display further includes a gas filling the second portion of the case at an overpressure and a vent communicating with the first portion of the case and communicating with an external environment. The vent at least partially equalizes the overpressure of the second portion with a pressure of the external environment.

An unmanned air vehicle comprises a fuselage that defines aerodynamic flight surfaces, an engine mounted to the fuselage having an engine shaft arranged to rotate about a longitudinal axis with respect to the fuselage, and a propeller mounted to the engine shaft so as to rotate to thereby provide thrust.
