Abstract

PURPOSE: To provide an aerodynamic stability while preventing a mechanical interference with a mother air-plane by a method wherein expanding wings are stored in a missile body, a locked state is released after delaying of a specified period of time with a delay chemical and an output chemical after launching and then the wings are developed with a twisting torque of a torsion bar. CONSTITUTION: Developing wings 3 are stored in an airframe 1, locked with a lock mechanism 7, mounted at a mother air-plane under this state and carried by it. As the missile is launched from the mother air-plane, a delay chemical is ignited and an output chemical is ignited after a certain time is delayed, a gas cylinder is operated and a lock mechanism 7 is released. With such an arrangement as above, the twisted state stored in a torsion bar 8 is returned to cause gears 9, 10, 12 and 13 to be rotated and the developing wings 3 fixed to the shaft of the gear 13 is rotated and developed. Accordingly, during a state in which the missile is mounted on the mother air-plane, the interference of the missile against the mother air-plane with the developing wings 3 is eliminated, resulting in that after launching of the missile, a maneuverability of the missile 1 as well as an aerodynamic stability can be sufficiently attained.
