Abstract
The paper presents the design and testing of a new pulse motor concept designated Dual-Inerrrupted-Thrust (DIT). The DIT motor incorporates two tandem propellant grains, separated by an interstage bulkhead which has a central opening or port. During operation of the first stage, the port, which is substantially larger than the nozzle throat, is closed by a frangible ceramic cover. When the second stage is ignited, the port cover shatters into small harmless fragments and the combustion gases flow without significant pressure losses into the empty first-stage chamber and out the nozzle.
