5. Unit agent. Gas for melting pressure of fuel tank of Sea Javelin ramjet and
gas for driving gas motor hydraulic pump in execution system are common
source, which are all unit agent I.P.N, as shown in Fig. 9.21. The gas
generated by Sam 2 (i.e., SA-2) unit agent I.P.N. is specifically used to drive
the propellant pump of liquid rocket engine, not to pressurize the propellant
tank before pump, as shown in Fig. 9.20.
(4) Classification of Missile-borne Auxiliary Energy and Its Primary Energy
1. Classified according to the working substance elements of auxiliary energy.
(a) Diversified auxiliary energy sources. For example, the Patriot is
three-source including electricity, gas and liquid, separate sources system; the Aspide is three-source including fuel, electricity and liquid,
common source system; the Chaparral is a fuel-electricity binary,
common source type; the Sam 3 (SA-3), Sam 6 (SA-6) is a
gas-electricity binary, common source type.
(b) Unitized auxiliary energy. For example, the French Rattlesnake, the
American Standard is unitary and co-source.
