Figure 9.32 shows a gas turbine pump system with a gas relief valve, a hydraulic
loading valve, and a self-pressurized tank. Its advantage is that the pressure control
of gas generator is stable and the service handling is simple. When the servo valve
is idle, the turbine will not overturn. Turbine coaxial drive generators and hydraulic
pumps provide power and hydraulic energy for the whole missile, so that the
auxiliary energy on the missile can be comprehensively utilized. Its disadvantage is
that without accumulator, the pressure is not constant enough to provide a larger
instantaneous supplementary flow. The system is suitable for hydraulic systems
with constant pressure and low instantaneous rudder deviation speed, no air source
equipment in technical position, poor service conditions, and no overturning
capability of turbopump. The Aspide air defense missile, which is commonly used
by the Italian armed forces, belongs to the gas turbine pump scheme with gas relief
valve and self-pressurized fuel tank.
It is noteworthy that the circulating hydraulic system without accumulator is rare
at home and abroad. In addition to British arrows and Italian Aspide, they have
basically accumulators, and even the hydraulic system of American Patriot electric
variable pump has a large gas-hydraulic accumulator. There are conditions without
