1.2 Test Article Description

Drogue Pressure Cartridge Assemblies (PCA)

The Drogue Pressure Cartridge assembly, P/N: SEH26151480-313/-316, consists of pressure cartridge housing nominally loaded with 850 milligrams (mg) of Hi-Temp propellant, and is initiated with a NASA Standard Initiator (NSI-3A) containing 114 mg of Zirconium Potassium Perchlorate (ZPP).

Figure 1: Drogue Pressure Cartridge Axis Definition

Drogue Riser Cutter The Drogue Riser Cutters are a guillotine device that is designed to cut the Kevlar bundles for the Drogue Parachutes. This device is actuated using Two of the Drogue PCA’s mentioned above.
