Testing and CFD Simulation of Diaphragm Hybrid Rocket Motors
47th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2011Combustion efficiency in standard hybrid rocket motors is usually low. This is due to the poor mixing of the core oxidizer flow with the gasi fied fuel from the walls. Motor scale increase usually worsens this issue. Large and volu metric inefficient post combustion chambers are common devices used to improve efficiency, while mixers are somewhat more ...

An analytical and experimental study of a hybrid rocket motor
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2014The hybrid rocket motor is a kind of chemical propulsion system that has been recently given serious attention by various industries and research centers. The relative simplicity, safety and low cost of this motor, in comparison with other chemical propulsion motors, are the most important reasons for such interest.

Development of a Hybrid Rocket Motor Using a Diaphragm for a Small Test Rocket
44th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2008For tactical missiles, hybrid rocket propulsion offers attractive advantages such as easy thrust control and compliance with insensitive munitions (IM) requirements. However, missile propulsion is highly constrained by volume and mass, and often requires a high thrust level and thrust per unit cross section.

Instrumentation of UALR labscale hybrid rocket motor
SPIE Proceedings, 2006The Central Arkansas Combustion Group has used a NASA EPSCoR grant to improve the instrumentation and control of its labscale hybrid rocket facility. The research group investigates fundamental aspects of combustion in hybrid rocket motors. This paper describes the new instrumentation, provides examples of measurements taken, and describes novel ...

Development of a N2O/HTPB hybrid rocket motor
33rd Joint Propulsion Conference and Exhibit, 1997Experiments were performed as a part of the Hybrid Propulsion Demonstration Program (HPDP) in order to demonstrate a N2O/HTPB hybrid sounding rocket. Multiple hybrid motors have been tested at Environmental Aeroscience Corporation in order to develop a high performance hybrid flight system.

Numerical Analyses of Thermal Protection Design in Hybrid Rocket Motors
AIAA Propulsion and Energy 2020 Forum, 2020Hybrid rockets can provide a similar degree of flexibility in the thrust profile as a liquid engine but keeping a much simpler architecture. In addition to deal with only a single liquid propellant, hybrids are often designed with some sort of ablative protection system borrowed from the less flexible solid rockets instead of the more complex ...

Design Trade-offs for Hybrid Rocket Motors
48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2012A new method is developed for preliminary design of hybrid rocket motors. A cooperative evolutionary method is used with an indirect approach to perform the coupled optimization of hybrid rocket motor and trajectory for a sounding rocket. Different propellant combinations are considered for a sounding rocket application (microgravity platform).

Results of Labscale Hybrid Rocket Motor investigation
28th Joint Propulsion Conference and Exhibit, 1992This work was performed to establish a labscale hybrid rocket motor test and evaluation capability at NASA Marshall Space Flight Center. The scope included activation of a Labscale Hybrid Motor, determination of baseline burning rates for PMMA fuel, and replication of pressure oscillations for HTPB fuel. The 0.820-in.-diam port, 10-in.-long fuel grains

Combustion Instability for Hybrid Rocket Motors with a Diaphragm
2019A diaphragm has been used to enhance fuel regression rate and combustion efficiency in hybrid rockets. On the other hand, it has been observed that significant pressure oscillations occurred. In this paper, main factor on the excitation of the instability was studied.
