Numerical research on the performance of solid fuel rocket scramjet combustor

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021
Combustion efficiency is the main factor affecting the performance of solid fuel rocket scramjet. To reveal the influence of combustor configuration on performance and further improve combustion efficiency, the influence of the width-height ratio of the rectangle-section combustor on the performance of solid fuel rocket scramjet is investigated ...

Experimental and Numerical Investigation of a Solid-Fuel Rocket Scramjet Combustor

Journal of Propulsion and Power, 2016
A new scramjet configuration using solid fuel as propellant is proposed, namely, the solid-fuel rocket scramjet. Experimental and numerical investigation of the solid-fuel rocket scramjet combustor was conducted to evaluate its performance. The experiment simulated a flight environment of Mach 4 at a 17 km altitude.

Energetic Solid Fuels for Ducted Rockets (II)

Propellants, Explosives, Pyrotechnics, 1991
AbstractThe combustion characteristics of variable‐flow ducted rockets were evaluated in order to obtain optimum design parameters of the gas generators. The energetic solid fuels used for the gas generators were glycidyl azide polymer (GAP) with burning rate catalysts.

Regression Rate Behavior of Hybrid Rocket Solid Fuels

Journal of Propulsion and Power, 2000
An experimental investigation of the regression-rate characteristics of hydroxyl-terminated polybutadiene (HTPB) solid fuel burning with oxygen was conducted using a windowed, slab-geometry hybrid rocket motor. A real-time, x-ray radiography system was used to obtain instantaneous solid-fuel regression rate data at many axial locations.
