  • THERMAL MANAGEMENT APPARATUS AND METHOD FOR ELECTRIC PROPULSION AIRCRAFT
    Publication number: 20260167343
    Abstract: A thermal management apparatus for an electric propulsion aircraft includes a first cooling channel configured to receive heat from a first cooling target component, a second cooling channel configured to receive heat from a second cooling target component, a heat exchanger in which a first cooling fluid having passed through the first cooling channel and the second cooling channel exchanges heat with outside air, and a first additional cooling unit configured to supply a second cooling fluid to the first cooling target component and the second cooling target component, wherein in a first situation, the first cooling fluid and the second cooling fluid cool the first cooling target component and the second cooling target component together.

  • Apparatus for preventing axial-flow compressor from stalling by employing casing treatment
    Patent number: 10378550
    Abstract: An apparatus for preventing an axial-flow compressor from stalling by employing a casing treatment includes an outer casing having an inner wall with a slot formed to face a rotor blade, an inner casing moveable so as to open the slot in an unstable operating region and close the slot of the outer casing in a stable operating region, and a drive means for moving the inner casing along the axial direction of the outer casing. Thus, the apparatus can be applied not only to a casing treatment structure where the slope of a slot does not vary with the rotational position of the rotor, but also to a casing with a variously shaped slot such as a radial slot or an axial skewed slot.
