(1) With the solidification of air defense missile engine, the use of method of
obtaining auxiliary energy from missile main propulsion system is less and less
when ramjet engine is seldom used and liquid rocket engine is seldom used.
(2) For medium-range air defense missiles, Aspide, which uses solid gas generator
and turbine as the primary energy combination, power supply to the whole
missile, and hydraulic source to be shared by pilot and seeker, is a successful
example of comprehensive utilization of missile-borne auxiliary energy and
common source with hydraulic.
(3) For small field air defense missiles and larger ship-to-air missiles, with the
emergence of high-efficiency thermal batteries and advanced electric steering
gear, in order to facilitate operational use and improve operational reliability,
most of them adopt a single power supply scheme to realize the modularization
of missile-borne auxiliary energy.
(4) For medium and long-range air defense missiles, the circulating hydraulic
energy still occupies the traditional advantage. With the development of related
technology, the accumulator system of battery motor hydraulic variable displacement pump (such as American Patriot) has replaced the fixed pressure
valve system of solid–gas generator turbo-hydraulic quantitative pump (such as
British Thunderbird) and the self-pressurizing tank system of liquid gas generator motor hydraulic variable displacement pump (such as British Sea
Javelin).
(5) Solid gas energy gas actuator and gas control still have considerable potential
for thrust vector control or vertical launching of small and medium-sized air
defense missiles.
(6) The influence of tradition is deeply rooted. For a considerable period of time,
for small and medium-sized air defense missiles, the main types of
missile-borne auxiliary energy of their respective improved models and successor models in Russia are cold air source, cold air turbogenerator, excretory
or circulatory hydraulic power source in the United States and Britain, as well
as thermal batteries and power unit in France.
(7) Missile-borne auxiliary energy is an important project in the development of air
defense missiles, which deserves great effort and careful study. The proper
selection of its scheme will directly affect the success or failure of the
missile-related subsystems and the whole missile, so it must be taken seriously.
Weight and space are the basic problems of scheme selection. As far as auxiliary energy is concerned, it can be achieved by improving mechanical efficiency and reducing energy loss.
