Evaluation of Paraffin-based Fuels for Hybrid Rocket Engines

50th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2014
This paper summarizes the investigations on the combustion behavior of paraffin-based hybrid rocket fuels with gaseous oxygen (GOX) as oxidizer. Combined experimental activities have been done at the DLR Institute of Space Propulsion in Lampoldshausen and at the Space Propulsion Laboratory (SPLab) of Politecnico di Milano.

Secondary combustion in a staged hybrid rocket engine

Journal of Mechanical Science and Technology, 2017
The 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 ...

Hybrid rocket engine, theoretical model and experiment

Acta Astronautica, 2011
Abstract The purpose of this paper is to build a theoretical model for the hybrid rocket engine/motor and to validate it using experimental results. The work approaches the main problems of the hybrid motor: the scalability, the stability/controllability of the operating parameters and the increasing of the solid fuel regression rate.

Numerical simulation of hybrid rocket engine flowfields

2013
Numerical simulations of the flow in a GOX/HTPB hybrid rocket engine are carried out with a Reynolds averaged Navier-Stokes solver including detailed gas surface interaction mass and energy balances. Global mechanisms are considered for the gas-phase chemistry.
