1. Variable energy variable flow output varies with ballistic conditions. Mainly
through gas pressure feedback, the flow of liquid unit agent (I.P.N) is
automatically adjusted by flow control valve to match the change of ballistic
conditions.
2. The whole system needs less total work, less oil, and lower temperature rise.
Because of the variable flow output matching primary energy and ballistic
conditions, there is no heating temperature rise of oil caused by the overflow
of constant flow output through relief valve bypass. The actual oil volume is
only about 355 ml, and the maximum dynamic range is up to 80 km.
3. The complex primary energy plant, inconvenient filling, and high toxicity of
unit agent are the drawbacks of this system. In the specific selection, the
conditions of working conditions, ballistic control measures and comprehensive utilization of energy, and other related issues must be fully considered, after balancing the pros and cons to determine.
(4) Control Method of Missile-borne Turbogenerator
The advantages of using turbogenerator as a power source are large power–
weight ratio, convenient test and inspection, and easy to realize the comprehensive utilization of missile-borne auxiliary energy, and common source
scheme. In order to ensure the stable output frequency and voltage of the
alternator, it is necessary to limit the speed of the turbine. There are many ways
to regulate the speed of turbogenerator. Here are some examples.
1. Hydraulic loading valves (or repressor valves) are installed in the coaxial
drive hydraulic pump system with the generator to prevent the crosslinking
effect of no-load hydraulic pump on generator overturn, such as the Italian
Aspide gas turbine generator described earlier.
2. The eddy current damper disk is installed in the generator, and the principle
that the eddy current damper is proportional to the rotational speed is used to
stabilize the rotational speed, such as the American Sea Sparrow gas turbine
generator.
3. Centrifugal governor is installed in the generator, and the relationship
between centrifugal throttling and rotational speed is used to control the air
intake to stabilize the rotational speed, such as Russian Sam 3 and 6 cold air
turbogenerator.
(5) Key Points for Selection of Missile-borne Auxiliary Energy Scheme
1. Single energy source and multiple energy sources. The rigidity of cold air
energy is poor, the size of cylinder structure is large, and the effect of
ambient temperature is great. Hydraulic energy has many advantages, such
as good rigidity, high power, and hard control characteristics, but it has
complex devices, multiple energy sources, and inconvenient use and
maintenance. Considering the tactical use, maintenance, and reliability, it is
better to use unitized missile-borne auxiliary energy.
