    摘要： The invention relates to an aerobraking device (20) for a man-made satellite from an atmospheric planet, including at least one aerobraking sail (25) connected to at least one propellant tank (21) so as to be unfurled by an inflation gas from such a tank (21). At least one leak monitoring device (37) is suitable for releasing a leakage rate of inflation gas in space when each aerobraking sail (25) is unfurled, this leakage rate being suitable to enable a suitable inflation rate to be supplied into the aerobraking sail (25) so as to enable same to be unfurled, and to completely discharge and passivate the propellant tank (21) and the aerobraking sail (25) after same is unfurled. The invention extends to an aerobraking method and to a spacecraft including such a device.

    摘要： Methods and apparatus for an adaptable solar airframe are provided herein. In some embodiments, an adaptable solar airframe includes a solar PV system having at least one solar tracking system and being able to follow the sun position in order to increase sunlight collection and power output; and an expandable body having an aerodynamic cross-section that minimizes parasitic air drag at any given thickness of the body, further being at least partially transparent to sunlight, further enclosing the solar PV system, and further being able to change its shape in response to changes in the positions of the solar PV system.

    摘要： Problem
    A shock wave suppression device (10) and an aircraft (1) capable of suitably reducing drag on a blade surface are provided.
    Solving Means
    A shock wave suppression device (10) is configured to suppress a shock wave generated on a blade surface (3a) of a blade (3), the shock wave suppression device including a bump cover (13) provided to follow the blade surface and deformable to protrude outward from the blade surface, and a displacing unit (14) configured to displace the bump cover between a steady state to follow the blade surface and a deformed state to protrude outward from the blade surface. The bump cover has a curved shape in the deformed state configured to be a continuous surface from an upstream side to a downstream side in a flow direction of a fluid flowing through the blade surface.

    摘要： A runback system for receiving fluid from a deicing system may comprise a body (202) and a first channel (212a) and a second channel (212b) defined by the body. A first end (214a) of the first channel may be spaced apart from a first end (214b) of the second channel. A second end (216a) of the first channel and a second end (216b) of the second channel may meet and form an outlet at an end of the body.
