Effect of Fluoroalcohol Chain Extension Modified HTPB Binder on the Combustion Performance of Aluminized Propellants

Crystals
To enhance both the mechanical properties of hydroxyl-terminated polybutadiene (HTPB) binder and the combustion efficiency of aluminized propellants, 2,2,3,3,4,4,5,5-octafluoro-1,6-hexanediol (OFHD) was employed as a chain extender to impart mechanical ...

HTPB Propellant Aging

Journal of Spacecraft and Rockets, 1981
Three HTPB propellants, varying in solids loading from 88% to 91%, were selected and developed for evaluation studies including aging. The 88%-solids propellant was verified to fit a previously developed aging model. The aging model has been further successfully applied to the measured mechanical-property aging data for the higher-solids propellants ...

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

Studying for the State Monitoring Time of HTPB Propellant

2016 9th International Symposium on Computational Intelligence and Design (ISCID), 2016
Using the finite element analysis to draw a certain type of HTPB propellent on duty in the natural storage and carrier state of stress - time curve, using the linear cumulative damage theory, the HTPB propellent of cumulative damage in both conditions are simulated and calculated the two states of cumulative damage factor, discuss the engine timing of ...

Solid Propellants based on ADN and HTPB

47th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2011
The aim of this work was to perform an initial evaluation of ammonium dinitramide, ADN, as substitute for ammonium perchlorate, AP, in solid rocket propellants for large space launch boosters. This paper includes performance evaluation, curing and compatibility assessments, propellant formulation and determination of ballistic properties.
