    Also gas pedal. A throttle in the form of a foot-operated pedal, or sometimes a hand-operated lever or paddle, by which the flow of fuel to the engine (and thereby the engine speed) is controlled, with depression of the pedal causing the vehicle to accelerate. admission stroke See induction stroke. aftermarket air brake 1. A type of brake in which the force that actuates the brake mechanism is ...

    en.wikipedia.org/wiki/Fan_clutch

    Engine fan with viscous drive. A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.

    Three-box form Alfa Romeo Giulia (Type 105) sedan/saloon Three-box form A categorization based on overall form design using rough rectangle volumes. In the case of the three-box form, there is a "box" delineating a separate volume from the a-pillar forward, a second box comprising the passenger volume, and third box comprising the trunk area—e.g., a Sedan.

    Turbofan, through a duct-fan; Turboprop, through an unducted propeller, usually with variable pitch; Turboshaft, a gas turbine optimized for producing mechanical torque instead of thrust; Ramjet, [21] similar to a turbojet but uses vehicle speed to compress (ram) the air instead of a compressor.

    Camber – the asymmetric curves on the top and bottom, or front and back, of an aerofoil; Canard – is an aeronautical arrangement wherein a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft. The term "canard" may be used to describe the aircraft itself, the wing configuration or the foreplane. [38] [39] [40]

  8. Dynamometer - Wikipedia

    en.wikipedia.org/wiki/Dynamometer

    A fan is used to blow air to provide engine load. The torque absorbed by a fan brake may be adjusted by changing the gearing or the fan itself, or by restricting the airflow through the fan. Due to the low viscosity of air, this variety of dynamometer is inherently limited in the amount of torque that it can absorb.

    Diagram of a fan disk Fan disk assembly diagram, showing one blade and attachment hardware Cross section of fan disk Failed fan disk recovered from the center engine of UAL 232. A fan disk is the central hub of a fan in a turbofan engine. Fan blades are attached to the fan disk, which is rotated by a shaft driven by a gas turbine. [1]
