In accordance with the present invention, there is provided a deployment device that is operative to deploy Special Material (SM) to protect the vehicle when an enemy infrared (IR) threat is present. The deployment device constructed in accordance with the present invention comprises at least one, and preferably a pair of canisters which are each filled or loaded with SM, then factory sealed to prevent oxidation or contamination. Each of the canisters included in the deployment device includes an input shaft which, when rotated, is operative to transmit the rotary motion to each of four threaded rods. The rods have two primary functions, which are to advance a piston thereby preloading the SM within the canister toward the open end thereof, and to turn rotary metering devices which are located at the open end of the canister. The advancing piston maintains consistent compression in the SM stack within the canister. Additionally, the rotary metering devices which are located in respective ones of the four corners of the canister at the aft end thereof control and thus meter how the SM is dispensed into the airstream behind the aircraft. In this regard, the rotary metering devices have external features that interleave with the stack of SM. As the rotary metering devices turn, the interleaving features continuously release and engage the SM stack, thus controlling the distinct amount of SM released. When stationary, the rotary metering devices positively retain the SM stack within the canister.

1. A deployment device for stacks of foils, comprising: at least one canister including: an elongate, tubular housing defining opposed forward and aft ends, and having an interior chamber which extends at least partially therethrough along an axis and defines a generally circular cross-sectional configuration;four elongate, rotatable drive members, each of the drive members including an elongate externally threaded rod, the drive members extending along the interior chamber in equidistantly spaced intervals of approximately 90°, in generally parallel relation to the axis, at least two drive members disposed in diametrically opposed relation to each other, one diametrically opposed pair of the drive members configured to rotate in a clockwise direction, and the other diametrically opposed pair of the drive members configured to rotate in a counterclockwise direction, wherein each of the drive members includes a drive gear which is operatively coupled thereto and concurrently rotatable therewith, each of the drive gears being positioned proximate the forward end of the housing, the drive gears being mechanically coupled to each other by a plurality of transmission gears in a manner wherein the rotation of any one of the drive gears by a corresponding one of the drive members facilitates the concurrent rotation of all of the drive ears and thus all of the drive members at substantially equal rotational speeds;four rotary metering devices cooperatively engaged to respective ones of the drive members and positioned proximate the aft end of the housing, the rotation of the drive members facilitating the concurrent rotation of the rotary metering devices, the rotary metering devices being cooperatively engageable to a stack of the foils disposed within the interior chamber; anda piston disposed within the interior chamber and cooperatively engaged to only a diametrically opposed pair of the drive members such that the rotation of the drive members facilitates the concurrent movement of the piston along the axis, and wherein a diametrically opposed pair of drive members do not contact the piston. 2. The deployment device of claim 1 further comprising a drive unit which is mechanically coupled to and operative to facilitate the rotation of one of the drive members. 3. The deployment device of claim 2 comprising a pair of canisters extending in side by side relation to each other, the drive unit being mechanically coupled to and operative to facilitate the rotation of one of the drive members of each of the canisters. 4. The deployment device of claim 1 further comprising an end cap which is pivotally connected to the housing proximate the aft end thereof, and is selectively movable between a closed position wherein the interior chamber is enclosed and sealed thereby, and an open position wherein the interior chamber is open to atmosphere at the aft end of the housing. 5. A deployment device for stacks of foils, comprising: at least one canister including: an elongate, tubular housing defining opposed forward and aft ends, and having an interior chamber which extends at least partially therethrough along an axis;four elongate, rotatable drive members, each of the drive members including an elongate externally threaded rod, the drive members extending along the interior chamber in spaced intervals of approximately 90°, in generally parallel relation to the axis, at least two drive members disposed in diametrically opposed relation to each other, one diametrically opposed pair of the drive members configured to rotate in a clockwise direction, and the other diametrically opposed pair of the drive members configured to rotate in a counterclockwise direction, wherein each of the drive members includes a drive gear which is operatively coupled thereto and concurrently rotatable therewith, each of the drive gears being positioned proximate the forward end of the housing, the drive gears being mechanically coupled to each other by a plurality of transmission gears in a manner wherein the rotation of any one of the drive gears by a corresponding one of the drive members facilitates the concurrent rotation of all of the drive gears and thus all of the drive members at substantially equal rotational speeds;four rotary metering devices cooperatively engaged to respective ones of the drive members and positioned proximate the aft end of the housing, the rotation of the drive members facilitating the concurrent rotation of the rotary metering devices, the rotary metering devices being cooperatively engageable to a stack of the foils disposed within the interior chamber; anda piston disposed within the interior chamber and cooperatively engaged to only a diametrically opposed pair of the drive members such that the rotation of the drive members facilitates the concurrent movement of the piston along the axis, and wherein a diametrically opposed pair of drive members do not contact the piston.
