Scalability and dynamic stability of hybrid rocket engines

Proceedings of 5th International Conference on Recent Advances in Space Technologies - RAST2011, 2011
This paper is divided in two parts. The purpose of the first part is to tackle the problem of geometrical scalability of hybrid rocket engines while the second part of the paper the stability of hybrid rocket motor is investigated using Liapunov theory.

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). High-pressure tests

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.

Optimal Robust Design of Hybrid Rocket Engines

2016
Hybrid rocket engines are flexible, safe, reliable, and low-cost and can be used in many aerospace applications. The engine design and operation are contingent on the type of designated mission and engine design is strictly related to trajectory optimization.

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.
