The LPU-23D/P series life preserver assembly contains an automatic inflator which is intended for use by an aircrew member in an ejection seat-type aircraft ONLY. It is designed as a constant wear item for use with the survival vest and will not interfere with the removal of the non-integrated parachute harness. Survival item pouches are attached to the life preserver casing. The dye marker and signal flares are not initially supplied and must be individually requisitioned.
Configuration
The LPU-23C/P flotation assembly is constructed of Nomex® fire-resistant cloth and consists of two independent flotation chambers. One chamber consists of the left waist lobe joined by a tube to the right collar lobe. This chamber contains the automatic/manual C02 inflation assembly (FLU-8B/P) series and the oral inflation valve attached to the left waist lobe. The other chamber consists of the right waist lobe joined by a tube to the left collar lobe. This chamber contains the automatic/manual C02 inflation assembly (FLU-8B/P) series and the oral inflation valve attached to the right waist lobe. The two chambers are sewn together at the collar lobes.
Function
Automatic inflation of the LPU-23/P life preserver occurs when immersion in water triggers the electronic circuit firing the explosive primer. The high-pressure primer gases force the piercing pin forward, releasing the inner end of the packaging cord loop and puncturing the 35 gram C02 cylinder which releases the pressurized gas. Automatic inflation is a one-time function of the FLU-8B/P inflator. A new inflator must be installed to replace the previously spent device. Manual inflation occurs when both beaded inflation handles are pulled straight out from the body. This action removes the locking pins securing the casing assembly about the waist lobes and activates the inflation assemblies. The hook and pile tapes securing the casing assembly about the collar lobes will separate as the preserver inflates. The FLU-8/P inflator may be operated manually and unlimited number of times without effecting the one-time automatic feature.
