circulation, and primary energy types, and obtains the key points of scheme
selection and the prediction of missile-borne auxiliary energy.
With the development of air defense missiles, the requirement of miniaturization
and portability of missile-borne equipment is getting higher and higher. As far as
missile-borne electronic equipment is concerned, the problem is relatively easy to
solve because of the small control power required by electronic components. For
missile-borne auxiliary energy, the corresponding heating, strength, materials, and
other issues are relatively difficult to solve because of the large driving power
required by the gas-hydraulic electromechanical equipment. The way is to
strengthen the study of ballistic conditions and put forward practical energy
requirements. The key point lies in how to rationally allocate and comprehensively
utilize the missile-borne auxiliary energy so as to make the scheme have the best
characteristics as far as possible.
The missile-borne energy of air defense missile should be broadly divided into
two parts: main energy (power plant propellant) and auxiliary energy (full-missile
power supply, guidance and control system energy, and supercharging energy for
propellant transport system of power plant). The configuration and comprehensive
utilization of missile-borne auxiliary energy are discussed below.
9.1.5.1 Classification of Energy Program
(1) Comprehensive Utilization of Energy in Propellant Conveying system of Power
Plant and Execution System
1. Cold air source. It is used not only in the propellant tank of turbocharged
liquid rocket engine, but also in the cold air actuator of control execution
system. For example, as shown in Fig. 9.20, the Russian SA-2 ground-to-air
missile series.
2. Gas source. After decompression of the gas produced by decomposition of
liquid unit agent (such as I.P.N isopropyl nitrate), the flexible rubber bag of
the fuel tank of the turbocharged ramjet is pressurized, at the same time, the
gas motor hydraulic pump is driven to supply oil to the hydraulic steering
gear. For example, as shown in Fig. 9.21, the British Javelin ship-to-air
missile.
3. Stamping air source. The high-speed ramjet air from the ramjet inlet drives
the fuel delivery pump and the hydraulic pump at the same time through the
ramjet turbine, which respectively supplies fuel to the ramjet and hydraulic
oil to the hydraulic steering gear. They are often used for coastal or
anti-aircraft missiles powered by certain ramjet engines, as shown in
Fig. 9.22.
(2) Comprehensive Utilization of Power Supply and Execution System Energy
1. DC power supply. Batteries on missiles supply power not only to electrical
equipment, but also to electric steering gear. As shown in Fig. 9.23, such as
