Typical mixing ratio for best cure is 88% HTPB - 12% Papi 94. To enhance the ablation rate, paraffin was added to the HTPB. UCLA also was static testing a hybrid motor adapted from commercial products to a design of their own. It is also used as a hybrid rocket fuel in conjunction with Nitrous Oxide (N2O). Solid propellants were, eventually, easier to make, safer to store, lighter in weight (because they did not require on-board pumps), and more reliable than their liquid predecessors. Two vehicle systems were built and alternately tested with replaceable HTPB-based fuel grain modules. A MODEL OF AP/HTPB COMPOSITE PROPELLANT COMBUSTION IN ROCKET-MOTOR ENVIRONMENTS Weidong Cai, Piyush Thakre, and Vigor Yang Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA 16802 A comprehensive theoretical/numerical model for treating AP/HTPB composite-propellant combustion in a rocket-motor environment is presented. These aluminum powders were used in manufacturing composite rocket propellants, that are based on Ammonium Perchlorate (AP) as oxidizer and Hydroxyl-Terminated-PolyButadiene (HTPB) as binder. HTPB is an excellent binder for solid rocket fuels, providing a solid but elastic fuel mass. The enhancement is due to the low viscosity and low surface tension of the surface melt layer of the paraffin during combustion. Kerosene delivers a specific impulse considerably less than cryogenic fuels, but it … Next » Hydroxyl-terminated Polybutadiene Resin w/CAO-5 Antioxidant & HX-752 Bonding Agent 1 Gallon. Alibaba.com offers 150 htpb for solid rocket propellant products. RCS Hydroxyl-terminated Polybutadiene (HTPB) resin premixed with 0.95% CAO-5 antioxidant and 2.38% HX-752 bonding agent. Comparing Hydroxyl Terminated Polybutadiene and Acrylonitrile Butadiene Styrene as Hybrid Rocket Fuels Stephen A. Whitmore, ... under vacuum, and then cast and cured in a fuel grain mold.


Our room temperature cure compound is perfect as a hybrid fuel, binder for solid motors, to make rubber components by casting, making insulation when used with silica microballoons, or as a slow curing rubber bonding agent. The petroleum used as rocket fuel is a type of highly refined kerosene, called RP-1 in the United States. HTPB is also used as a hybrid rocket fuel. Petroleum fuels are usually used in combination with liquid oxygen as the oxidizer. Each rocket also included a commercial altimeter chip which relayed the results to display on a cellphone application. Other articles where Solid propellant is discussed: rocket and missile system: From liquid to solid fuel: …generation of missiles, powered by solid propellants.


This is the classic solid rocket motor binder! [3] It will also be oxidized by high-test peroxide in the land speed record attempt Bloodhound SSC . The HTPB fuel developed by SpaceDev is nonvolatile, making it easier and safer to store than other materials. The classic hybrid rocket which employs hydroxyl-terminated polybutadiene (HTPB) fuel is characterized by low ablation rate. It is readily available in 5-gallon (19-liter) drums and inexpensive, Benson said. HTPB-Polyurethane: A Versatile Fuel Binder for Composite Solid Propellant 231 90 °, and number of scans = 300. … Two vehicle systems were built and alternately tested with replaceable HTPB-based fuel grain modules. About 30% of these are polymer. Altitudes ranged from 1600 to 2400 feet.

UCLA also was static testing a hybrid motor adapted from commercial products to a design of their own.

HTPB R-45M is the highest-grade binder for military applications, providing low-temperature flexibility, excellent adhesion to metal and excellent dispersion of fillers.
