Hybrid rocket engines: The benefits and prospects
Aerospace Science and Technology, 2007The review of research avenues for working processes (ignition, combustion, etc.) in hybrid rocket engines (HRE), for thermal protection and power characteristics is stated. Based on conducted design and exploratory studies and design developments, the reasonable fields of application of HRE to launch systems for orbit insertion of payload are ...

Optimal battery selection for hybrid rocket engine
AIP Conference Proceedings, 2022 In the present paper, the optimal selection of batteries for an electric pump -fed hybrid rocket engine is analyzed. A two -stage Mars Ascent Vehicle, suitable for the Mars Sample Return Mission, is considered as test case. A single engine is employed in the second stage, whereas the first stage uses a cluster of two engines.

Numerical investigations of hybrid rocket engines
Acta Astronautica, 2018Abstract Paper presents the results of numerical studies of hybrid rocket engines operating cycle including unsteady-state transition stage. A mathematical model is developed accounting for the peculiarities of diffusion combustion of fuel in the flow of oxidant, which is composed of oxygen-nitrogen mixture.

Hybrid Gas Generator for a Staged Hybrid Rocket Engine
Journal of Propulsion and Power, 2017The two-stage combustion hybrid rocket engine with a hybrid gas generator method offers numerous advantages over a solid-propellant gas generator and classical hybrid rocket engines. These advantages include a higher specific impulse in operation, lower lifecycle costs, and lower sensitivity to combustion pressure.

Restart transients of hybrid rocket engines.
Journal of Spacecraft and Rockets, 1973Experimental investigation of the problems associated with restarting hybrid rocket motors (i.e., motors wherein a liquid or gaseous oxidizer is injected into the port of a solid fuel grain with subsequent mixing and combustion of the oxidizer and fuel) following a brief period of extinguishment. The results include the finding that the ignition delay

Secondary combustion in a staged hybrid rocket engine
Journal of Mechanical Science and Technology, 2017The staged Hybrid rocket engine (HRE) is a relatively new concept that minimizes a loss of combustion performance with an oxidizer to fuel ratio shifting, while maintaining the key advantages of HREs. Knowing that a key component of the staged HRE is the secondary combustion, in this study a reacting flow Computational fluid dynamics (CFD) based tool ...
