Development and Testing of a Fast-Acting, 8-Bit, Digital Throttle for Hybrid Rocket Motors

Fire
The potential for throttle control of hybrid rocket systems has long been known as a potential advantage for a variety of applications. Because only a single flow path is controlled, theoretically, hybrids should be significantly easier to throttle than ...
