Dual Thrust Motor
</dt>
A solid-propellant
rocket engine built to obtain dual
thrust.
</dd>
In a single chamber unit the booster propellant grain may be bonded to
the sustainer grain, with the thrust level regulated by mechanically changing
the nozzle throat area or by using different grain compositions or
configurations. In a dual-chamber unit, the separate chambers may be arranged
in tandem, or concentrically. [[/a>|/a>
