Hybrid Rocket Engines

2012
The hybrid rocket engine utilizes a combination of solid rocket and liquid rocket technology to meet some flight mission applications. In terms of performance, cost, availability of materials and safety, the hybrid approach does potentially have some advantages.

Transient behavior in hybrid rockets

33rd Joint Propulsion Conference and Exhibit, 1997
The combustion dynamics in hybrid rockets is studied to provide a basic input into transient motor processes, such as ignition, throttling, thrust termination and instability. The model treats the time dependent heat flow into the fuel, with ablation at the surface. The gasification uses a single effective heat to account for surface processes, such as

Development of a Student Hybrid Rocket

48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2012
Nammo Raufoss AS with the support from Andoya Rocket Range has developed a novel small diameter hybrid rocket, the SHR110, for carrying student experiments and small payloads to 10km altitude approximately. The rocket engine is based on a nitrous oxide hybrid rocket motor providing an environmentally clean alternative to the surplus military rockets ...

Micro and Full-Scale Experiments on Hybrid Rocket Fuel and Prelude to Hybrid Rocket Combustor Simulations

49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013
The high density polyethylene, as hybrid rocket fuel, has been chosen to be studied. Thermogravimetric analysis allowed to determine an Arrhenius type equation for its regression rate. A flash pyrolysis coupled to GC/MS/FID has been used to observe influence of oxidative environment on pyrolysis byproducts quantity.

Performance Additives for Hybrid Rockets

2016
Addition of performance-improving materials in the solid hydrocarbon fuels of hybrid rockets has been studied extensively both in academia and also in the industry. The primary motivation has been to improve the specific impulse, density impulse, and regression rate performance of the propulsion system.
