Sustainer dngineslare intended to prov4delinterplgnetary flight
into outer space.' These motors can be both 'single mode and multimoee.
In the latten case, they can change the value and the direction of
the thrust sector. A gradual variation in the thrust! level 6an be
accomplished by switching the, motors in the power installation-,o
and off or by continUously varlible control. Sustainer, mdv.s cn
