Influence of Propellant Composition on the Performance of a Gel Rocket Combustion Chamber

AIAA Propulsion and Energy 2019 Forum, 2019
Gel propellants offer the possibility to build throttleable and versatile propulsion systems with easy handling and improved operational safety. The combination of performance flexibility and storage characteristics merges the major advantages of liquid and solid propulsion systems.

Optimisation and performance evaluation of an environmentally friendly rocket composite propellant

Indian Chemical Engineer, 2018
ABSTRACTThis paper investigated the effects of laboratory synthesised rocket composite propellants’ formulations on propellant performance parameters using response surface methodology (RSM). For the sake of a safe environment, the propellant is made of chemical constituents that have less severe effects on air quality.

Some new results of chuffing in composite solid propellant rockets

Journal of Spacecraft and Rockets, 1985
Chuffing is one of the low-frequency instabilities in solid propellant rockets functioning at low chamber pressures. In chuffing, the rocket motor experiences brief spurts of combustion and consequent pressure buildup, followed by periods of near ambient pressures in the combustion chamber.

The effect of compositional variables upon oscillatory combustion of solid rocket propellants

Combustion and Flame, 1964
Abstract In this test programme, a laboratory scale burner was used to study the oscillatory combustion of a composite propellant system. The results show that the variation of binders (polysulphide, polyurethane and polybutyl-acrylic acid) had a comparatively small effect upon the oscillatory combustion of the propellant system.

CHARACTERIZATION OF THE FLAME STRUCTURE OF COMPOSITE ROCKET PROPELLANTS USING LASER DIAGNOSTICS

2021
This work presents the development and/or application of several laser diagnostics for studying the flame structure of composite propellant flames. These studies include examining the flame structure of novel energetic materials with potential as propellant ingredients, the near-surface flame structure of basic composite propellants, and the global ...

An Experimental Assessment of Soil Contamination by Composite Solid Rocket Propellants

AIAA SCITECH 2025 Forum
Since the beginning of the space era, solid propulsion has been considered an important technological asset for heavy launchers. Compositions based on ammonium perchlorate represent the current state of the art. The combustion of this class of propellant releases chlorine-based products, though.
