(d) Medium and long-range ramjet is the circulating hydraulic energy for
variable displacement pump driven by gas motor.
8. Primary energy
(a) Gas pressurization and cold gas pressurization. The boosting mode of
propellant delivery system of liquid rocket engine or ramjet engine
mainly depends on the traditional design idea. For example, the helium
of Patriot Driver pressurizes the hydraulic accumulator and the
hydraulic tank at the same time. In terms of safety and reliability, the
sequence of gas chemical stability is helium, nitrogen, and air in turn.
(b) Gas drive and cold air drive. For the turbopump of propellant delivery
system, gas is usually used to drive, and for the turbogenerator, there are
two driving modes. The former has higher power and higher efficiency
than the latter.
(c) Solid Charge Gas and Liquid Unit Gas. According to the requirement of
control execution system, the former is suitable for constant power
output energy with high percentage of load cycle, not too long working
time and unadjustable gas flow, such as Aspide. The latter is suitable for
variable power output energy, such as Sea Javelin, which has low load
cycle percentage, long working time, and adjustable gas flow.
(d) Gas turbine and gas motor. Two kinds of gas driving devices of
hydraulic circulating system, which are matched with solid–gas constant power system and liquid–gas variable power system, respectively,
are the main driving components of this system.
(e) Power Supply. Compared with early chemical batteries, gas turbine
generators have the main advantages of high specific power in terms of
weight and size, and do not require large converters.
(f) Stamping air. It is only suitable for ramjet-powered missiles and should
be used comprehensively.
Typical examples of missile-borne auxiliary energy schemes for air defense missiles
are shown in Table 9.10.
9.1.5.3 Summary
The development of missile-borne auxiliary energy of air defense missile depends
on the development trend of air defense missile and its related subsystems. The
main development trends of modern air defense missiles are power solidification,
guidance dual-mode (radar, infrared), seeker initiation (active radar), fuze laser,
control dual (aerodynamic and thrust vectors), transmission digitization, implementation of electrodynamics, power battery (a large number of thermal batteries
and converters), and launch simplification (inclined to adopt box vertical launching
or nonmanagement launch mode after launching).
