Abstract
A hybrid rocket engine system has: an oxidizer tank containing a liquid oxidizer; a rocket engine having a combustion chamber operatively connected to the oxidizer tank; a solid propellant fuel within the combustion chamber; a nozzle fluidly connected to the combustion chamber, the nozzle having a convergent section and a divergent section downstream of the convergent section; and a thrust vector control device operatively connected to the divergent section of the nozzle and operable to inject a fluid through at least one aperture defined through the divergent section for controlling a direction of a thrust generated by the rocket engine.

A hybrid rocket engine system, comprising:
- an oxidizer tank containing a liquid oxidizer;
- a rocket engine having a combustion chamber operatively connected to the oxidizer tank;
- a solid propellant fuel within the combustion chamber;
- a nozzle fluidly connected to the combustion chamber, the nozzle having a convergent section and a divergent section downstream of the convergent section;
- and a thrust vector control device operatively connected to the divergent section of the nozzle and operable to inject a fluid through at least one aperture defined through the divergent section for controlling a direction of a thrust generated by the rocket engine.
A divergent section of a convergent-divergent nozzle of a rocket engine, the divergent section having a monolithic body, the monolithic body defining a wall extending circumferentially around a central axis, at least one aperture extending through a thickness of the wall, the monolithic body further defining at least one conduit protruding away from the wall and connected to the at least one aperture.
A method of manufacturing a divergent section of a nozzle of a rocket engine, comprising manufacturing a monolithic body using an additive manufacturing process to define a wall circumferentially extending around a central axis and to define at least one conduit protruding away from the wall.
