HiPPAG stores ejection

Eaton PCS HiPPAG® 500 Series systems are designed to meet the demanding requirements of precision ejection systems and provide flexibility of installation within ejector racks, aircraft pylons or in internal weapons bays on high-performance manned and unmanned military aircraft platforms. The system minimizes logistics footprint by eliminating the need for pyrotechnic cartridges, other single-shot devices and their associated support equipment. Continuous control of system pressure ensures an accurate and repeatable separation of store from the aircraft.

Eaton PCS HiPPAG® 300 Series systems provide reliable always available pure gas for missile seeker cooling applications. It eliminates the need for gas bottles with their associated logistics chain and so reduces lifecycle costs and gas management is no longer a concern as pure gas is always available.

The HiPPAG® system has two primary applications:

  • Providing high pressure cold gas for the clean, reliable and repeatable ejection of stores from military aircraft.
  • Providing high pressure pure gas for missile seeker cooling without the logistics footprint associated with refillable gas canisters.

Eaton PCS provides a range of storage and control products to enable the integration of cold gas systems into a wide range of platforms.

Ejector Valves and Accumulators

  • Designed to fit within an Ejector Release Unit (ERU)
  • Receives and stores the high-pressure dry air produced by the HiPPAG® or ground charge system
  • Typically 0.2 to 0.7 liters based on the store size and end-of-stroke velocity requirements
  • A pressure balanced servo mechanism and dual-coil firing solenoid valve releases the gas to the ejector rams
  • EVA pressure transducer relays the air pressure in the EVA to the aircraft
  • Manual vent valves are provided to safely depressurize the EVA for maintenance

High-pressure vessels

  • For the storage of pure air, nitrogen or argon gases
  • In operational use for cryogenic cooling, cold gas actuation and fuel tank pressurization
  • Bottles can either be single use sealed for life or refillable through a solenoid valve
  • Volumes range from a few cubic centimeters up to 2.4L
  • Mainly stainless steel or titanium
  • Designed to military standards
  • DEF-STAN 81-91 or DEF-STAN 00-970
