The properties vary because HTPB is a mixture rather than a pure compound, and it is manufactured to meet customers' specific requirements. A typical HTPB is R-45HTLO. [ 1 ] This product consists of oligomeric units typically containing 40–50 butadiene molecules bonded together, with each end of the chain terminated with a hydroxyl [OH] group:
American Rocket Company (AMROC) developed the largest hybrid rockets ever created in the late 1980s and early 1990s. The first version of their engine, fired at the Air Force Phillips Laboratory, produced 312,000 newtons (70,000 lbf) of thrust for 70 seconds with a propellant combination of LOX and hydroxyl-terminated polybutadiene (HTPB ...
RocketMotorTwo is a hybrid rocket engine utilizing solid hydroxyl-terminated polybutadiene (HTPB) fuel and liquid nitrous oxide oxidizer – sometimes referred to as an N 2 O/HTPB motor [8] [9] – providing 70,000 pounds-force (310 kN) of thrust. [10] The design makes use of lessons learned during the development of the SpaceShipOne hybrid ...
The Rochester Institute of Technology was building an HTPB hybrid rocket to launch small payloads into space and to several near-Earth objects. Its first launch was in the Summer of 2007. Scaled Composites SpaceShipOne, the first private crewed spacecraft, was powered by a hybrid rocket burning HTPB with nitrous oxide: RocketMotorOne.
The history of the Trinidad and Tobago national oil company can be traced to 1969, when the government established the National Petroleum Company. The company, the Trinidad-Tesoro Petroleum Company Ltd, was a partner in a joint venture with Tesoro Corporation , and was formed to acquire the assets of British Petroleum as it exited operations in ...
The SRMU was the largest motor Hercules had ever built, and it was also its first use of HTPB binder. [10] [11] Early in development, a test segment was lost due to improper fuel casting. [12] In 1990, prior to the first stacking of the motor, the crane assembling the booster dropped a segment, causing it to roll away from the test area and ...
Hoechst AG (German pronunciation: [ˈhøːçst]) was a German chemicals, later life sciences, company that became Aventis Deutschland after its merger with France's Rhône-Poulenc S.A. in 1999. With the new company's 2004 merger with Sanofi-Synthélabo, it became a subsidiary of the resulting Sanofi-Aventis pharmaceuticals group.
