maximum comprehensive deflection angle of the full-motion wing is not more
than 22
, and other aerodynamic configurations rarely exceed 35
. Otherwise,
it will easily make the missile out of control, increase the aerodynamic
resistance, increase the nonlinearity and asymmetry of the control mechanism,
and make the arrangement of the mechanism more difficult.
(9) The quality, volume, reliability, and cost of the control execution system have
a great influence on the overall performance of the air defense missile control
system. Therefore, in the overall design of the control execution system, the
above indicators must be fully demonstrated, comprehensively analyzed, and
comprehensively compared. Figure 9.12 shows the weight optimization work
band of the control execution system with time as abscissa, weight as ordinate,
power as reference index, and load cycle percentage as condition. Similarly,
the optimal work band for volume, reliability, and cost can be obtained. The
basic types of the optimal or suboptimal control execution system can be
determined by calculating the intersection of the above indicators with overlapping method, considering the counter-maneuverability, the comprehensive
utilization of missile-borne auxiliary energy. and other special factors.
(10) There are six relative criteria for comprehensive evaluation of control execution system, including complexity, reliability, maintainability, cost, performance, and development potential. Usually, the most important concern is
relative performance. Systems with good technical performance tend to be
more complex, less reliable, and more expensive, but the impact on weight and
volume is not obvious. This is because the weight and volume depend mainly
on the system structure, design technology, structural materials, and manufacturing process. Reliability and cost are not sensitive to volume or even
weight. They are functions of complexity and number of parts, and are related
to maintainability. Therefore, comprehensive consideration should be given to
the comprehensive evaluation of the control execution system.
