Detonability of Solid Composite Propellants

ARS Journal, 1961
The thin film pla t inum resistance thermometer (heat flux gage) has been successfully applied to measurement of heat fluxes from initiators for solid propellants. Hea t fluxes measured were as high as 1000 Btu/ft-sec from hot, particleladen reaction products of pyrotechnic igniters.

Prediction of the Critical Diameter of Composite Propellants

AIAA Journal, 1972
A theoretical model which predicts the critical diameter of composite propellants is presented. A previously published detonation model is corrected and refined by use of a new model which considers both single grain size AP and dual grain size AP configuration s, for both porous and nonporous propellants.

Nano-composites for rocket solid propellants

Composites Science and Technology, 2005
Aim of this work is the study of different components (binder and aluminum powders) of solid propellants used for rocket propulsion to improve ballistic performance. New propellant formulations have been tested and characterised. Combustion residues were collected by a proprietary method and analyzed both from the morphological and chemical point of ...

HNF/HTPB BASED COMPOSITE PROPELLANTS

International Journal of Energetic Materials and Chemical Propulsion, 2002
In a search for new storable high performance propellants for the European Space Agency (ESA), the solid oxidiser Hydrazinium Nitroformate (HNF) was identified as a very promising ingredient for a new storable composite propellant. Two distinct advantages of HNF based propellants over presently used Ammonium Perchlorate (AP) based propellants rvere the

Composite Materials in Propellers

Aircraft Engineering and Aerospace Technology, 1989
THE introduction of the pure jet gas turbine propelled aeroplane appeared to herald the demise of the propeller as a means of propulsion for other than small or specialised machines.

Optimized Design of Composite Propeller

Mechanics of Advanced Materials and Structures, 2004
ABSTRACT Traditional propellers are made of high-stiffness metal material. They deform only slightly and are usually designed to work at a constant speed, operating at reduced efficiency at other speeds. This research designs a composite propeller that operates over a wider range of speeds.
