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.

Thrust modulation in hybrid rocket engines

Journal of Propulsion and Power, 1988
An experimental investigation of hybrid rocket engines (HRE) is performed to study the throttling performance within a thrust range of 10:1. In order to improve the throttling properties over the entire thrust range, the method of secondary gas injection (gasification) was used. The injection gases were reactive (O2) and inert (N2).

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.

Testing 1kN Paraffin-Based Hybrid Rocket Engine

2019
The present paper describes the design and testing activities carried out on a 1000 N hybrid rocket demonstrator, including a preliminary data assessment. Gaseous oxygen and a paraffin-based solid fuel represent the hybrid propellants. The demonstrator configuration and the design logic are presented first.
