As the unity of control and structure and the joint of signal flow and power flow,
the control execution system is not only the execution system of control system, but
also the component of missile structure. As the main hardware equipment of missile
control system, the control system requires high specific performance and specific
power. Because its performance not only affects the frequency characteristics of
missile control system, but also affects the frequency coupling between auxiliary
energy and control mechanism, as well as the dynamic flutter and static divergence
of aeroelasticity of control surface, its design plays an important role in the whole
missile design.
The objective of missile control execution system design is to optimize the
comprehensive performance, and it is feasible. To achieve this goal, it mainly
depends on two aspects: on the one hand, it depends on the rationality of the
indicators required by the overall implementation system and the feasibility of
scheme selection; on the other hand, it depends on the technological advancement
and the effectiveness of the design method adopted by the execution system. Next,
the design idea and method of air defense missile control actuation system are
summarized from the overall point of view. The key points are to clarify the
comprehensive requirements, to clarify the restrictive conditions and extreme
environmental conditions, to conduct demonstration and analysis, to determine the
main criteria, and to verify performance indicators.
9.1.4.1 Comprehensive Requirements
(1) The basic design requirements are shown in Table 9.8.
(2) The additional design conditions are shown in Table 9.9.
9.1.4.2 Demonstration Process
Before the missile control system, launch control system and telemetry system put
forward the design requirements for the control actuation system, it needs to go
through the necessity demonstration. Before accepting the task of development, the
control actuation system must make feasibility analysis. The important issues of
demonstration and analysis are as follows:
(1) The series of the execution system depends on whether the series of the missile
adopts gas rudder for vertical launch control (e.g., American sparrow is a
single-stage missile, but adopts vertical launch control, so it is still two-stage).
The number of actuating systems depends on the setting of rudder and aileron
(There are rudders and ailerons separated, such as the French rattlesnake, Sam
6 of the Soviet Union; there are also rudders and ailerons integrated, such as
Sea Sparrows, Aspide, Italy), and the differential mode of rudder and aileron
(Mechanical differential, such as Sam 2 of the Soviet Union; Electrical differential, such as Sea Sparrows). The installation space of the execution
