  • Patent number: 11920617
    Abstract: Fluid systems and methods for addressing fluid separation are described. An example fluid system includes a main body and a fluid pressurizer. The main body has a first portion, a second portion, an injection opening, a suction opening, a channel that extends from the suction opening to the injection opening, and a side wall. The first portion has a first axis that extends along the side wall. The second portion has a second axis that extends along the side wall at an angle relative to the first axis such that when fluid flows over the main body flow separation is defined adjacent to the second portion. The injection opening is disposed at a first location relative to said flow separation. The suction opening is disposed at a second location relative to said flow separation. The channel extends from the suction opening to the injection opening.

  • Publication number: 20240067353
    Abstract: Inlet systems are described. An example inlet system has a first wall, a second wall, and a compressor. The first wall has a first end, a second end, and defines a passageway, a first passageway opening, and a second passageway opening. The passageway extends from the first passageway opening to the second passageway opening. The first wall and the second wall cooperatively define an inlet, an outlet, and a channel. The channel extends from the inlet to the outlet. The compressor is disposed within the passageway and is configured to pressurize fluid that passes through the passageway. The first end of the first wall is disposed outside of the channel. The passageway is in fluid communication with the channel.

  • Publication number: 20240010325
    Abstract: Fluid systems are described. An example fluid system includes a body and a housing. The body has a leading edge, a trailing edge, a first portion, and a second portion attached to the first portion. The second portion is moveable relative to the first portion between a first position and a second position. The housing extends from the first portion to the second portion and is configured to move as the second portion moves relative to the first portion. The housing is moveable between a first configuration and a second configuration. The housing is in the first configuration when the second portion is in the first position and is in the second configuration when the second portion is in the second position. The housing has a first length when in the first configuration and a second length when in the second configuration that is greater than the first length.

  • Publication number: 20230075112
    Abstract: An example of a deflected slip stream wing system with coflow jet flow control includes a wingbox, a flap, a compressor, and a propulsor. The wingbox has a root and a tip. The flap is moveably attached to the wingbox and has a leading edge, a trailing edge, an injection opening, a suction opening, and a channel. The injection opening is disposed between the leading edge and the suction opening. The suction opening is disposed between the injection opening and the trailing edge. The channel extends from the injection opening to the suction opening. The compressor is disposed within the channel. The propulsor is disposed on the wingbox between the root and the tip. The propulsor has an off state and an on state. When in the on state, the propulsor is aligned relative to the flap such that fluid accelerated by the propulsor contacts the flap.
