Hydrazine thruster 30 minimizes impulse bit degradation by making the hydrazine more reactive with the catalyst 66 by using higher temperature hydrazine and smaller catalyst grain, and also concentrates the injected hydrazine in smaller catalyst volume 66 so that heat released aids decomposition of a greater quantity of injected hydrazine.

A hydrazine thruster for pulse mode operation comprising: thrust chamber means for containing a hydrazine dissociation catalyst and having a centerline; hydrazine injector means for injecting liquid hydrazine into said thrust chamber means substantially only along said centerline and directly into said catalyst in a plurality of successive pulses, said injector means and said thrust chamber means for containing a hydrazine dissociation catalyst being arranged so that during repetitive pulsing insufficient residual hydrazine is stored in the catalyst bed so that hydrazine bed temperature does not decrease from the temperature at the initiation of one pulse to the temperature at the initiation of the next pulse; means for supplying pulses of liquid hydrazine to said hydrazine injector means; and an outlet from said thrust chamber from which hot gases exit said thrust chamber to produce thrust, there being sufficient hydrazine injected into said thrust chamber means by said hydrazine injector means so that for each pulse the impulse bit, which is the summation of the product of thrust times time, is at least 0.0045 pound seconds.
