The invention relates to the technical field of layout design of unmanned plane systems, specifically to an unmanned plane system combined with all-wing oblique wing planes by using a wingtip connecting/towing technology. The unmanned plane system is composed of the plural identical all-wing unmanned planes which are connected in parallel through a wingtip-coupling mode. Wings and an engine of each unmanned plane can rotate relative to each other around a rotating shaft in the horizontal direction. The wingtip-coupling mode is that the left and right wingtips of each all-wing unmanned plane are provided with corresponding wingtip coupling and towing mechanisms, and every two coupled all-wing unmanned planes are only capable of doing relative movements of rotating around a coupling shaft. The system can increase the lift-drag ratio effectively and enable each unmanned plane to achieve a longer flying range and better endurance. Moreover, the flight capabilities in a middle-low speed zone, a subsonic speed zone, and an ultrasonic speed zone are all taken into account. When necessary, the in-flight detachment or recombination of the planes can be realized according to the actual situations, such as task requirements or atmospheric conditions.

A head and neck restraint device controls the motion of the head and forces exerted upon the neck of a seated occupant in a decelerating vehicle. A body defines a collar, right and left legs and right and left wings. The collar is tethered to the helmet. Each leg has belt interaction surfaces that provide a friction action on the shoulder straps. Left and right extensions or wings residing under the shoulder strap rearward of the legs provide a restriction of rotation of the body and thus a binding action on the shoulder straps. A cantilever action is induced in generally forward impact by the tethers pulling on the collar of the body and the binding action on the shoulder straps reducing the forward motion of the body. The present restraint device does not attach to the structure of the vehicle, allows travel thereof with respect to the seated occupant, yet controls the motion of the occupant's head in order to substantially reduce neck loads on the occupant. Moreover present restraint device is not in contact with the occupant during normal operation and thus does not induce discomfort or fatigue. Under general forward impact conditions, the occupant's head motion is controlled with respect to the torso, yet the device will restrictively move with the driver's head and torso along shoulder straps of a seat harness of the vehicle.
