A projectile and method of deploying a projectile includes a wing deployment system for deploying a wing of a projectile. The wing deployment system includes a stored energy release mechanism that is activated to generate an initial range of motion of the wing and a panel arranged on the wing and configured to cause an angular acceleration of the wing during the initial range of motion of the wing.

The control surface according to the present invention controls an attitude of a flying object, and includes a skin covering an internal space and a lattice structure supporting the skin in the internal space. The lattice structure has mechanical strength that is changeable in one or both of a surface length direction and a surface width direction. For example, the mechanical strength at a root of the control surface in the surface length direction may be made larger than the mechanical strength of other regions in the surface length direction, or the mechanical strength at a front edge and a rear edge in the surface width direction may be made larger than the mechanical strength of other regions in the surface width direction.

The present disclosure provides a payload activation device. The payload activation device comprises a camera having a fixed focal length, arranged to capture an image of an object on a platform for carrying a payload having the payload activation device, wherein, when the payload is in a first position relative to the platform, the image of the object is in a first focused state and, when the payload is in a second position relative to the platform, the image of the object is in a second focused state. The payload activation device also comprises a processor configured to determine whether the image of the object is in the first focused state or the second focused state and to cause actuation of an activation mechanism within the payload when the image of object is in the second focused state to activate the payload. The present disclosure also provides a deployable payload having the payload activation device and an aircraft for carrying the deployable payload.

A projectile including an ejectable aft fin housing assembly. The aft fin housing assembly includes aft fins that increase a distance between a center of gravity and a center of pressure of the projectile, improving passive stabilization of the projectile. Once the projectile has been passively stabilized, the aft fin housing assembly is ejected, decreasing a distance between the center of gravity and the center of pressure, improving active stabilization of the projectile.

A range extension unit extends the range of a guided mortar bomb. The range extension unit includes a housing interface defining an internal cup that receives a rear portion of a guided mortar bomb, wherein the housing interface covers a rear portion of the mortar bomb. The housing interface, when coupled to the mortar bomb, collectively forms an aerodynamically shaped body with the mortar bomb. At least two deployable wings are attached to the housing interface, wherein the wings transition between a retracted state and a deployed state.

A pivot connection part for a flying machine includes an inner body, an outer body radially surrounding the inner body, and a set of connection elements configured to connect the inner body to the outer body. Breaking the connection elements detaches the inner body from the outer body. A first blocking assembly having a cam and a stop is configured to block relative rotation between the inner and outer bodies in a first rotational direction. A second blocking assembly having a pawl and a resilient stop blade is configured to block relative rotation between the inner and outer bodies in a second rotational direction.
