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 ...

Swirl Injection Hybrid Rocket Motor Design and Testing
47th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2011This project involves the design, manufacturing, and testing of the Cal Poly Space System’s M-class 98mm hybrid rocket motor. The 20 inch-long motor utilizes hydroxylterminated polybutadiene as fuel with 600 psi liquid nitrous oxide as the oxidizer. Modeling and analysis was conducted on a 12 port self-impinging swirl injector and fuel manufacturing to

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.

Design and optimization of variable thrust hybrid rocket motors for sounding rockets
Science China Technological Sciences, 2011Besides safety and low-cost, the start/shutdown/restarting and throttling ability are the other two significant advantages of hybrid rocket motors (HRMs) compared with liquid and solid ones. In this study, a two-stage variable thrust and non-toxic 98%HP/HTPB hybrid rocket motor (VTHRM) is designed and applied in a sounding rocket, and the design ...

Vortex combustion in a hybrid rocket motor
2016The work is focused on a vortex flow pancake hybrid rocket motor (VFP). This hybrid rocket configuration is characterized by two flat solid fuel disks and a tangential injection between them. The gap between the two flat disks serves as combustion chamber.

CFD Simulations of Self-pressurized Nitrous Oxide Hybrid Rocket Motors
2018 Joint Propulsion Conference, 2018Delft Aerospace Rocket Engineering has developed a 1 kN hybrid rocket motor, using Nitrous Oxide\nas oxidizer and a mixture of Sorbitol and Paraffin as fuel. The thesis starts with the numerical simulation of the rocket motor firing. The simulation provides the trend over time of motor parameters such as mass flow rates, vapor quality of the oxidizer ...

Eco-Friendly Propellant for Hybrid Rocket Motor
2018Conventional propulsion systems mostly based on the propellants which are highly toxic in nature. In a single rocket, the amount of such propellant is generally hundreds of tons. When this huge amount of propellant burnt, it develops a large amount of unburnt particles as well as gases which damage the ecosystem.
