MIL-HDBK-143A
console - A grouping of controls, indicators. and similar electronic or mechanical equipment,
used to monitor readiness of and/or control specific functions of a system, such as missile
checkout, countdown, or launch operations.
constant-bearing course - A missile trajectory wherein the line-of-sight from the vehicle to
the target maintains a constant direction in space.
constant m control - The method of controlling a missile ROCKET MOTOR by keeping the
Mach number (m) constant rather than the velocity of the vehicle. This method is used
because of the ease of measuring parameters required for the control and because other
parameters are a function of the Mach number rather than the velocity.
constant velocity control - The reverse of constant m control wherein a missile power plant is
controlled to maintain a constant velocity rather than a constant Mach number.
CONTROL, ALTITUDE, GUIDED MISSILE - A specifically designed control that is manually
preset to establish maximum altitude of a Guided Missile's flight.
CONTROL, GUIDED MISSILE WARHEAD ARMING DEVICE -An item specifically
designed to control the operation of an arming device for a Guided Missile warhead. Cf:
ARMING DEVICE, GUIDED MISSILE WARHEAD.
CONTROLLER, FLIGHT MISSILE GUIDANCE SET - A specifically designed, manually
preset item for controlling a Guided Missile in pitch, yaw, and roll, through a missile guidance
set, prior to acquisitions by remote command guidance.
control rocket - A vernier engine or retrorocket used to change the attitude, direction, or
velocity of a missile in flight.
control system - In a Guided Missile, the units which maintain missile stability about the yaw,
pitch, and roll axes, and which also receive signals from the command guidance system and
convert these into mechanical movements of the engines or aerodynamic surfaces to change or
maintain the missile course.
control vane - A movable tab or aerodynamic surface attached to a missile airframe and used
to control the flight attitude of the vehicle.
cooldown - The reducing of the temperature in cryogenic containers and associated piping to
lessen the thermal shock and boil-off when liquid oxygen or liquid nitrogen are introduced
into them. Usually accomplished by allowing amounts of the cryogenic fluids to circulate
through the system and boil-off, thereby absorbing residual heat in the container.
cooling, film - The cooling of a body or surface. such as the inner surface of a ROCKET
ENGINE combustion chamber by maintaining a thin fluid layer over the affected area
