  • Publication number: 20220111955
    Abstract: A method for improving a blade in an end zone of the blade, spanwise along the blade, and such an improved blade and a rotor comprising the improved blades. The leading edge of the aerodynamic profiles situated in the end zone is shifted from the upper surface half-profile towards the lower surface half-profile, then the leading edge sections of the two half-profiles are modified in order to connect the leading edge to the intermediate sections of the two half-profiles. Next, the blade is manufactured according to the modified aerodynamic profiles. Consequently, the negative camber of the aerodynamic profiles of the blade is thus increased, helping improve the aerodynamic performances of the blade during hovering flight.

  • Publication number: 20220111978
    Abstract: A carrier rocket system, with a carrier rocket, together with a launch assistance unit, which is detachably connected, or connectable, to the carrier rocket. The carrier rocket system is set up to take off in a horizontal launch via the launch assistance unit when thrust is generated by at least one propulsion unit of the carrier rocket. The launch assistance unit can be detached from the onward-flying carrier rocket after supersonic velocity has been reached, and is set up to fly back to the earth's surface after its detachment from the carrier rocket. The launch assistance unit preferably provides all the necessary structural supports to enable a carrier rocket that has been designed for a vertical launch to use one or more of its essential components without structural modifications. Also disclosed are a take-off method for a carrier rocket system, and a manufacturing method for a carrier rocket system.

    Abstract: Disclosed is a method for task planning of a space information network based on resource interchange. The method includes: initializing basic parameters of the space information network; dividing a planning horizon into K time slots of equal length, and constructing a resource time-varying graph for the space information network; sampling a feasible resource combination space of each task, and obtaining a candidate resource combination set comprised of the resource combinations with independence greater than or equal to a threshold n; calculating a conflict relation between resource combinations, and constructing a resource combination conflict graph; obtaining a maximum independent set of the resource combination conflict graph to obtain a global planning result; and searching a neighborhood of the global planning result, and completing a local adjustment of a task planning scheme through the resource interchange, to complete the task planning based on characteristics of the resource interchange.

  • Publication number: 20220111980
    Abstract: A system and method for installing, deploying, and recovering a plurality of spacecraft that provides an ease of use and structural stability, and facilitates a standardization of spacecraft design. In embodiments of this invention, threaded rods are arranged orthogonal to a surface of a baseplate, and each spacecraft includes a coupling mechanism that selectively engages or disengages each threaded rod. Each spacecraft is added to the stack by engaging its coupling mechanism and rotating the threaded rods while the preceding spacecraft on the stack disengage their coupling mechanisms, thereby enabling the spacecraft to travel along the threaded rods toward the baseplate. When all of the spacecraft are added to the stack, the stack is preloaded by rotating the treaded rods into a terminator component at the top of the stack while the coupling mechanisms in all of the spacecraft are disengaged. Spacecraft are deployed by reversing the process.
