Each of the radial fingers is also confined under a radially extending tab on a central collar. A base plate, concentric with the collar, has pins that extend through slots in the fingers to prevent their rotation in the plane of the base plate. A tension spring attached at one end to the base plate and at the other end to the collar exerts force to rotate the collar relative to the base plate. It is kept under tension by a retaining pin inserted through aligned holes in the base plate and collar. A load pin, one end of which is attached to the drogue parachute, extends centrally through the collar and base plate. The opposite end of the load pin is equipped with a flange that attaches to the retaining pin. This flange is also equipped with a shear pin that extends through an ear that is perpendicular to the load plate. A compression spring surrounds the load pin and is confined between the inside end of a hollow guide, fixed to the load plate and the load pin flange. The shock produced by opening of the drogue parachute breaks the shear pin and allows the decelerating force produced by the drogue parachute to be supported by the base plate until the deceleration approaches a desired, terminal velocity. At that time, the compression spring operates to withdraw the retaining pin from the collar, allowing it to be rotated by the tension spring. This rotation moves the radial tabs of the collar away from the ends of the fingers, so that they are no longer confined thereby. The fingers then fall out of the flare, releasing the entire mechanism, together with the drogue parachute.,下面是Release mechanism for flare parachute专利的具体信息内容。

1. In an aerial flare having a cylindrical case with a shoulder therein and a drogue parachute, the improvement comprising apparatus for automatically releasing the drogue parachute from the flare, after it has decreased the velocity of the flare sufficiently, comprising: a base plate having a central hole and a smaller diameter than that of the inside of the flare case; a central load pin attached at one end to the drogue parachute and having an outwardly extending flange fixed to its other end, the pin extending through the central hole of the base plate; a compression spring surrounding the central pin and operatively confined between the flange thereof and the base plate; a shear pin attaching the load pin to the base plate for fixing the normal position of the load pin relative thereto; a collar surrounding the load pin and having a plurality of radially extending tabs; a plurality of radially extending fingers, each confined at one end under one of the tabs and at its other end under the shoulder in the flare case; means for preventing rotation of the fingers in the plane of the base plate; spring means for biasing the collar to rotate relative to the base plate; and a retaining pin operatively fixed to the central pin and extending through aligned holes in the base plate and collar, whereby the spring means may be maintained under tension.
2. The aerial flare of claim 1 wherein the spring means is a tension spring attached at one end to the base plate and at the other end to the collar.
3. The aerial flare of claim 1 wherein the means for preventing rotation of the fingers comprises at least two pins fixed to the base plate and extending through slotted holes in each finger.
4. The aerial flare of claim 1 further including a cylindrical guide fixed in the central hole of the base plate and surrounding the central load pin and its compression spring, the guide having an inwardly projecting flange on the end thereof that is opposIte the flange on the central pin, so that the spring may be confined between the flanges.
5. Apparatus for automatically releasing a drogue parachute from an aerial flare having a cylindrical case with a shoulder therein, comprising: a base plate having a central hole and a smaller diameter than the interior of the flare case; a central load pin attached at one end to the drogue parachute and having an outwardly extending flange on the other end thereof; a compression spring surrounding the load pin and confined between the flange thereof and the base plate; a shear pin attaching the central pin to the base plate, that may be broken when the drogue parachute is deployed; a collar surrounding the central pin and having radially extending tabs thereon; a plurality of fingers, each confined at one end under one of the tabs and at its other end under the shoulder of the flare case, whereby the mechanism may be retained therein; spring means biasing the collar to rotate relative to the base plate; means for preventing rotation of the collar until the drogue parachute has decreased the velocity of the flare; and means for preventing rotation of the fingers in the plane of the base plate.
6. The apparatus of claim 5 wherein the means for preventing rotation of the collar comprises a retaining pin fixed to the flange of the load pin and passing through aligned holes in the base plate and collar, whereby the collar is prevented from rotating until the force exerted on the load pin by the drogue parachute becomes weaker than the opposing force of the compression spring, whereupon the compression spring may withdraw the retaining pin from the aligned holes to permit rotation of the collar.
