Abstract: Various embodiments of a vortex hybrid motor are described herein. In some embodiments, the vortex hybrid motor may include a housing with a solid propellant positioned within the housing, and an injector ring positioned at a proximal end of the housing. The injector ring can include a plurality of angled injector units each including a first injector and a second injector angled towards an impingement point. A first fluid stream of a liquid propellant dispensed from the first injector can collide with a second fluid stream of the liquid propellant dispensed from the second injector to atomize the liquid propellant and form a spray fan formation. At least one of the first injector and the second injector can be positioned at an injection angle relative to the sidewall to create a swirl flow of the atomized injector fluid.

Abstract: Various embodiments of a vortex thruster system is described herein that are configured to create at least three discrete thrust levels. In some embodiments, the vortex thruster system includes a catalyst bed configured to decompose a monopropellant at more than one flow rate and deliver the decomposed monopropellant into a vortex combustion chamber for generating various thrust levels. In some embodiments, the catalyst bed includes a screen assembly positioned within the inner chamber of the catalyst bed. The screen assembly can include alternating reactive screens and inert screens. The reactive screens can include a catalytic coating for assisting with decomposing the monopropellant, and the inert screens can provide structural support for the screen assembly. Related systems, methods, and articles of manufacture are also described.
