  2. Overspeed - Wikipedia

    en.wikipedia.org/wiki/Overspeed

    In a propeller aircraft, an overspeed will occur if the propeller, usually connected directly to the engine, is forced to turn too fast by high-speed airflow while the aircraft is in a dive, moves to a flat blade pitch in cruising flight due to a governor failure or feathering failure, or becomes decoupled from the engine.

  3. Ground effect (cars) - Wikipedia

    en.wikipedia.org/wiki/Ground_effect_(cars)

    "Porpoising" is a term commonly used to describe a particular fault encountered in ground-effect racing cars. Racing cars had only been using their bodywork to generate downforce for just over a decade when Colin Chapman 's Lotus 78 and 79 cars demonstrated that ground effect was the future in Formula One, so, at this point, under-car ...

  4. Motor constants - Wikipedia

    en.wikipedia.org/wiki/Motor_constants

    The motor may not reach this theoretical speed because there are non-linear mechanical losses. On the other hand, if the motor is driven as a generator, the no-load voltage between terminals is perfectly proportional to the RPM and true to the of the motor/generator.

  6. Direct-drive mechanism - Wikipedia

    en.wikipedia.org/wiki/Direct-drive_mechanism

    In high-speed motors, this effect is usually negligible, as the frequency at which it occurs is too high to significantly affect system performance; direct-drive units will suffer more from this phenomenon unless additional inertia is added (i.e. by a flywheel) or the system uses feedback to actively counter the effect.

  7. Power band - Wikipedia

    en.wikipedia.org/wiki/Power_band

    The power band of an internal combustion engine or electric motor is the range of operating speeds under which the engine or motor is able to output the most power, that is, the maximum energy per unit of time. This usually means that maximum acceleration can be achieved inside this band (often at the cost of lower efficiency).
