摘要： A propulsion system, including a rotor arrangement rotatably mounted with respect to a nacelle about a rotor axis. The rotor arrangement includes rotor blades, each being pivotably mounted to a hub element about a respective blade pivot axis, the rotor blades being deployable between an undeployed configuration and a deployed configuration. The nacelle includes a nacelle body having a nacelle outer surface including facet elements and transition elements, each facet element extending aft from the hub element, each adjacent pair of facet elements being circumferentially spaced from one another by a corresponding transition element, each facet element having a first curvature with respect to the rotor axis, each transition element having a second curvature with respect to the rotor axis. The first curvature is different from the second curvature. In the undeployed configuration, each rotor blade is in overlying and fully external relationship with respect to a corresponding facet element.

摘要： A system and method for tracking moving objects located within an area of interest are described. A sequence of periodic frames of the area is generated from LiDAR measurements. The sequence includes preliminary periodic and periodic operational frames. Each periodic frame includes point cloud data including static object data and dynamic object data. The static data are filtered out by applying a pattern mask generated by using the predetermined number of the preliminary periodic frames. For each periodic operational frame, clusters of points related to the dynamic object data are generated. Tracks of the moving objects are constructed from clusters related to the same object. The clusters are obtained for a predetermined number of the periodic operational frames. Each cluster is defined by a characteristics vector associated with a moving object in a corresponding periodic operational frame. Each characteristics vector includes cluster parameters associated with the corresponding moving object.

摘要： A launch system is provided, including a composite vehicle and a carrier vehicle. The composite vehicle includes a payload vehicle, a booster vehicle and a first coupling system. The payload vehicle is configured for powered spaceflight at least in a space medium, and includes a rocket driven propulsion system. The booster vehicle is configured for powered supersonic/hypersonic aerodynamic flight, includes a ramjet propulsion system, and is configured for transporting the composite vehicle between a first altitude and a second altitude under propulsive power provided by the ramjet propulsion system. The first coupling system is configured for selectively coupling and decoupling the payload vehicle with respect to the booster vehicle. The carrier vehicle is configured at least for powered subsonic/transonic/supersonic aerodynamic flight, and for transporting the composite vehicle to at least the first altitude from a ground location. The launch system also includes a second coupling system for selectively coupling and decoupling the composite vehicle with respect to the carrier aircraft.

摘要： A floor system designed for use with an aircraft is provided. The aircraft comprises a cabin characterized by a first capacity defined by the number of personnel in a predetermined position which may be accommodated therein, and comprises an auxiliary fuel port. The floor system is configured to be detachably installed within the cabin and comprises one or more top panels constituting, when the floor system is installed in the aircraft, a floor of the cabin, and one or more fuel tanks disposed below the top panels and defining an internal space for containing liquid fuel there within. At least one of the fuel tanks is configured for connection to the auxiliary fuel port for supplying the fuel to the aircraft. The cabin with the floor system installed therein is characterized by a second capacity being equal to the first capacity.

摘要： Distributed radar systems and techniques for processing data received from such distributed radar systems. The distributed radar systems may utilize data on beam spatial pattern for processing collected signals and determining direction of one or more reflection origins (e.g., one or more objects reflecting transmitted signal).
