9.1.6 Hydraulic Energy Application Technology of Gas
Turbine Pump for Aircraft
9.1.6.1 Application of Gas Primary Energy
Gas technology is widely used in missile control actuation system. In addition to
gas servo mechanism and its energy, it is mainly used as primary energy of missile
hydraulic system, directly pressurizing hydraulic tank or indirectly driving
hydraulic oil pump through turbine and motor. The former belongs to extrusion
hydraulic system, while the latter belongs to circulation hydraulic system. As a
primary energy source, gas is used in the circulating hydraulic system of tactical air
defense missile, which can be divided into two categories: one is the common gas
turbine quantitative pump (Fig. 9.29); the other is the rare gas motor variable pump
(Fig. 9.30).
Gas turbopump usually uses solid charge gas generator, and hydraulic plunger
pump is a quantitative pump. Its advantages are simple composition and easy to
use. It is suitable for hydraulic servo mechanism with complex trajectory conditions, high load cycle percentage, high average power, and not too long working
time. The disadvantage is constant power output, gas parameters cannot be
adjusted.
Gas motor pumps usually use liquid unit gas generators. Gas motor pump is a
variable displacement pump. This gas driven linear (reciprocating) motor pump is
essentially a gas turbocharged accumulator with cycle travel and continuous
