10.3 Device for Changing Missile Motion Direction
by Using Gas Generator and Transverse Force
of Nozzle
The main advantage of using gas generator and nozzle to generate transverse force
is that the magnitude of transverse force is less dependent on the flight speed of
missile. There are many types of transverse force generating devices. The system
consists of the following main components: gas generator, gas nozzle, ball valve,
and solenoid control elements. The position of the nozzle is located near the front
end of the missile and distributed uniformly along the circumference. The number
of nozzles is generally three to four or more.
Figure 10.19 shows the first structure of the transverse force generator. The gas
generated by the gas generator 5 in the figure pass through the ball valve 8 and is
discharged by the nozzle 7, thus generating the transverse force. Here, three nozzles
are evenly distributed around the circumference. Component 9 is a star-shaped
linkage plate. It should have three arms relative to the number of nozzles. The
center of the star-shaped linkage plate is supported on a spherical or hemispherical
support, so it can tilt in all directions. Component 6 is the control cable, whose
direction is consistent with the missile’s longitudinal axis. One end is connected
with the corresponding arm of the star-shaped linkage plate, and the other end is
fixed on the restrictor 1 of the anchor plate 3. If the solenoid 4 is not activated, the
gas power acting on the three ball valves tightens the three control cables through
the stem 10 and the star linkage plate 9. At this time, the amount of gas discharged
from the three nozzles is equal, and the three forces produced offset each other.
Now if a lateral force is needed in the direction of a nozzle, the electromagnets of
the other two valves are activated simultaneously, attracting the anchor plate 3 and
pulling two corresponding control cables. The control cable pulls the corresponding
arm of the star-shaped linkage plate, thus jacking the corresponding stem 10,
