ABSTRACT:
A rocket (100) is disclosed having a body (101) with a bay (102) therein and a hatch (109) which is movable between a bay opened position and a bay closed position by a spring biased hinge (110). The hatch is pivotally coupled to a nose section (104) by a spring biased hinge (11). The hatch is configured to be engaged and disengaged with a catch (118) mounted to the rocket body. With the initial forward movement of the launched rocket the inertia and/or the force of the wind upon the nose section causes the disengagement of the catch whereby the continued movement of the rocket creates a wind upon the nose section which maintains the hatch in its bay closed position. However, as the rocket reaches its apogee the biasing force of the spring biased hinge (110) overcomes the force of the wind upon the nose section so as to pivot the nose cone so as to disengage the hatch for parachute release
