Propulsion Means Or Accessory Patents (Class 434/54)
  • Patent number: 11851189
    Abstract: A hybrid air mobility system is capable of flying a long distance through effective operation of an engine and batteries. The hybrid air mobility system includes a fuselage configured to supply power to a propeller and electric equipment, the fuselage being provided with a duct including an inlet and an outlet so as to circulate air to the engine and the electric equipment; a deflector rotatably installed at the outlet of the duct so as to convert a discharge direction of exhaust gas generated by the engine and cooling air after cooling the electric equipment; and a controller configured to determine whether or not the engine is driven and to control a rotated position of the deflector depending on an amount of driving of the engine so as to selectively adjust movement of the exhaust gas and the cooling air towards the propeller.

  • Patent number: 4537025
    Abstract: A fuel control for a gas turbine engine is operable in a training mode in addition to the conventional automatic and manual back-up modes. In the training mode the manual mode is simulated, with signals commensurate with operator action being delivered to the fuel metering valve actuator, while protection against exceeding the safe operating limits of the engine is provided.
