Solid-Fuel Regression Rate Modeling for Hybrid Rockets
Journal of Propulsion and Power, 2013 The regression rate of the solid fuel is a primary parameter in the performance analysis for a hybrid rocket. Many studies in the past few years have theoretically claimed, or experimentally shown, a dependence of the regression rate on the chamber total pressure. Such behavior is generally traced back to the presence of oxygen below the flame zone and

Spread and burning behavior of continuous spill fires [PDF]
, 2017 Spill fire experiments with continuous discharge on a fireproof glass sheet were conducted to improve the understanding of spill fire spread and burning. Ethanol was used as the fuel and the discharge rate was varied from 2.8 mL/s to 7.6 mL/s.

International Journal of Turbomachinery, Propulsion and Power, 2020 Injection pattern of the oxidizer injected into the combustion chamber is a significant factor in evaluating the performance of a hybrid rocket. In the hybrid rocket combustion process, oxidizer flows over the solid fuel grain surface, leading to a ...

Study on Thermal Degradation Characteristics and Regression Rate Measurement of Paraffin-Based Fuel
Energies, 2015 Paraffin fuel has been found to have a regression rate that is higher than conventional HTPB (hydroxyl-terminated polybutadiene) fuel and, thus, presents itself as an ideal energy source for a hybrid rocket engine.

Additively manufactured aluminium nested composite hybrid rocket fuel grains with breathable blades
Virtual and Physical Prototyping, 2023 Hybrid rocket engines suffer from the restricted mechanical properties and low regression rates of current polymeric fuel grains. We propose a three-dimensional printed aluminium (Al) nested composite fuel grain with millimetre-scale lattice pores ...
