Wing deployment mechanism and design method using pneumatic technique

A mechanism for deploying a wing from an airborne body, wherein the mechanism comprises:

• a frame made of materials designed to meet aerodynamic and material strength requirements;
• a deployment cylinder mounted to said frame, the deployment cylinder provides a pneumatic means for creating an angular momentum, hence rotates the wing, wherein the deployment cylinder comprises a pneumatic piston and a first spring wrapped around a push rod;
• a gas canister mounted to said frame, wherein the gas canister releases gas into a chamber of the deployment cylinder, causing a pressure to propel the pneumatic piston;
• a pipeline connecting the gas canister to the deployment cylinder;
• a pyrotechnic valve positioned in the pipeline between the gas canister and the deployment cylinder;
• a rotation shaft about which the wing is rotated from an inactive state position to an active state position, said rotation shaft being mounted to the frame;
• a locking pin for locking the wing in an active state;
• a flange mounted on the frame for supporting the wing for rotation about the rotation shaft, and comprising a groove that keeps the locking pin at a compression condition during the inactive state;
• and
• the flange comprising a locking pin hole for receiving said locking pin when the wing is in an active state, wherein at the moment that the wing reaches its active state position, the rotation will be stopped when the locking pin snaps into to the locking pin hole,
• wherein actuation of said piston causes rotation of the flange about the rotation shaft.
