    Abstract: A launcher for unmanned aerial vehicles (UAV), the launcher having a foldable UAV stowed within said launcher, the launcher includes, a launch tube configured as a UAV launcher and a UAV carrying case. The launcher further includes a pneumatic booster connected to said UAV for accelerating said UAV during launching phase. The launcher further includes a separation mechanism operated to permits separation of the booster from the UAV when the UAV leaves the launcher tube and to transfer the kinetic energy that is created from the pneumatic booster to the UAV in the launching phase. The UAV is propelled off of the launch tube by the booster that transmits thrust in the launch tube to the space below said booster. The UAV which is connected to the booster by the separation mechanism is pushed out of the launcher tube body and leaves the launch tube, the booster is separated from the UAV by the separation mechanism and the UAV is automatically deployed. The UAV propellers are activated to propel the UAV and driven the UAV.

    Abstract: An arm linkage foldable device for a UAV (unmanned aerial vehicle) includes a linkage module and two connection modules. The linkage module includes a guided structure and a slider. The slider slides along the guided structure. Two aircraft arms located at two sides of the fuselage are respectively connected with two sides of a slider through the two connection modules, a joint of every connection module and the slider is rotatable. A protruding portion is located on every connection module, a slide groove is provided on the fuselage corresponding to the protruding portion, the protruding portion is inserted into the slide groove and slides along the slide groove. The slider moves along the guided structure to drive one connection module to move, the connection module drives one aircraft arm to move with the slider and rotate relatively to the slider, so that the aircraft is unfolded or folded.

    Abstract: An exemplary rotational assembly includes a base having a circular collar and first and second arms that rotate about the circular collar in opposite angular directions. In a stored state the arms have substantially the same angle relative to the circular collar; in a deployed state the arms have rotated into opposing positions. Each end of a Nitinol wire is coupled to the first and second arms and contracts when heated by the flow of electrical current. This contraction causes the simultaneously application of a rotational force to the first and second arms causing the first and second arms to rotate about the circular collar in opposite angular directions. The simultaneous counter rotating angular forces during rotation of the arms causes no substantial change in angular inertia at the base.
