A typical APCP propellant mixture produces 2–3 times the specific impulse of the black powder propellant used in most smaller rocket motors. HTPB is also used as a hybrid rocket fuel. [ 2 ] With N 2 O ( nitrous oxide , or "laughing gas") as the oxidizer, it is used to power the SpaceShipTwo hybrid rocket motor developed by SpaceDev . [ 3 ]
Hydrogen peroxide works best as a propellant in extremely high concentrations (roughly over 70%). Although any concentration of peroxide will generate some hot gas (oxygen plus some steam), at concentrations above approximately 67%, the heat of decomposing hydrogen peroxide becomes large enough to completely vaporize all the liquid at standard pressure.
Polybutadiene acrylonitrile (PBAN) [1] copolymer, also noted as polybutadiene—acrylic acid—acrylonitrile terpolymer [2] is a copolymer compound used most frequently as a rocket propellant fuel mixed with ammonium perchlorate oxidizer. [3] It was the binder formulation widely used on the 1960s–1970s big boosters (e.g., Titan III and Space ...
The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant.
Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that ...
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 ...
Mostarac was furious with the response. “Thank you Airbnb,” she snarked in the post’s caption. “As always, their policies failed to account for context,” she declared in a follow-up post.
It's chock-full of vegetables like carrots, potatoes, and parsnips, and flavored with zesty spices like ginger and turmeric. Get Ree's Chicken Stew recipe. Will Dickey.
