DESCRIPTION: |
Cylindrical body of sheet metal tapered at one end from 9 1/2 inches to approxima-tely 4, which section has a lead weight and four membrane covered ports approximately two inches in diameter. The after end of the flare case is closed by a canvas bag con-taining a parachute. The candle is in a central tube so mounted as to keep the burning mixture at the top of the flare by spring action. |
OPERATION: |
When the flare is removed from the box the adhesive tape on the cover is pulled off and membranes covering the ports on the nose are punctured. |
The flare is loaded into the bomb rack with the pointed end of the flare toward the forward end of the plane. |
Sufficient static line is pulled from the pocket in the parachute canvas bag to allow the ring attached to the end of the line to be secured to the arming wire retainer on the rack or shackle. |
On launching, a combination type fuze causes a delay before the pyrotechnic candle burns. |
REMARKS: |
1. Flares having a one minute delay fuze may be released at elevations between 100 and 4000 feet. |
2. 5-1/2 minute delay may be released from greater altitude. |
3. Descent it at a rate of between 80 and 100 feet per minute. |
4. A continous illumination of nine (9) minutes durstion may be obtained by dropping a Mod 0 and a Mod 1 together. |
