| Description: |
|---|
| The cartridge has a cylindrical aluminum case designed for electric firing from an aircraft multi-barrel ejector. Successive round fire control is by an intervalometer to time flashes with camera exposure requirements. Assembled in the base of the cartridge case is in electric primer; a black powder propelling charge, a primer shield assembly, and gas-check wads. The remaining space is occupied by a photoflash charge case with a built-in delay fuse and detonator. The delay time of the fuse is marked on the cartridge case. The cartridge is stored and shipped with a metal shunting clip over the base to protect the primer form accidental firing. |
| Use: |
|---|
| This cartridge is used to provide illumination for night aerial photographic reconnaissance. |
| Functioning: |
|---|
| The electrically fired primer ignites the propelling charge. The propelling charge ignites the delay fuse and ejects the photoflash flash case from the cartridge case. At the end of the delay time, the delay fuse ignites the detonator, which ignites the photoflash charge, and the photoflash case explodes to produce a flash brilliant enough for night aerial photography. |
