What is double base propellant?
Definition of double-base powder : an explosive powder or propellant that contains nitrocellulose and nitroglycerin as the essential components — compare single-base powder.
What is propellant binder?
The binder is the elastomeric matrix which contains the oxidizer and metallic fuel particles in composite propellants. Since it is the continuous phase of a solid propellant, the binder must serve a multitude of functions.
How do I make ammonium perchlorate?
Ammonium Perchlorate can be made by adding Ammonia gas, Ammonium Hydroxide or Carbonate to Perchloric acid. Ammonium Perchlroate can also be make via Lithium Perchlorate and Ammonium Carbonate. The Lithium Carbonate so produced is insoluble and will precipitate leaving the Ammonium Perchlorate in solution.
What is the chemical formula for ammonium perchlorate?
NH4ClO4
Ammonium perchlorate/Formula
What is triple base propellant?
Triple-base propellant [r]: Smokeless powder, used in artillery, made from nitrocellulose, nitroglycerin or another explosive plasticizer, and nitroguanidine; it burns with equivalent energy, but at a lower temperature than other propellants, thus reducing barrel wear, and has much less muzzle flash [e]
What are the types of propellant?
Double based propellants are used in small arms, cannons, mortars and rockets. Triple Based Propellant Triple based propellants consist of nitrocellulose, nitroquanidine, nitroglycerin or other liquid organic nitrate explosives. Triple based propellants are used in cannons.
How do you make sugar propellant?
Using the scale, measure 14 grams of potassium nitrate or saltpeter (KNO3) and 7 grams of sugar. This makes enough propellant for a single 2″-long rocket motor. Blend the ingredients by placing them into a tightly covered plastic container with a handful of large lead fishing weights or . 50-caliber lead balls.
Which polymer is used for solid fuel rocket propellant?
Ammonium perchlorate (AP)-based composite propellants have been a workhorse in the field of solid rocket propulsion for more than five decades. This type of propellant typically contains a multi-modal distribution of AP (NH4ClO4) grains (∼20 to 200 mm) embedded in the hydroxyl-terminated polybutadiene (HTPB) matrix.
What is a rocket binder?
A binder can be anything that, when added to the propellant. fills in the spaces between the particles, and glues the whole mass together. Ideally, a binder should take part in the combustion reaction, so rocket makers normally choose a binder that doubles as a fuel.
What is APCP fuel?
Ammonium perchlorate composite propellant ( APCP) is a modern fuel used in solid-propellant rocket vehicles. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by the nature of how it is processed.
What is APCP (Ammonium perchlorate composite propulsion)?
Ammonium perchlorate composite propellant (APCP) is the most-used solid propellant composition in space launch applications (e.g. the Space Shuttle’s Reusable Solid Rocket Motor, Orbital ATK’s Star motor series).
How does APCP differ from other solid rocket propellants?
It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by the nature of how it is processed. APCP is cast into shape, as opposed to powder pressing as with black powder.
What is the chemical composition of propellant?
The propellant is most often composed of ammonium perchlorate (AP), an elastomer binder such as hydroxyl-terminated polybutadiene (HTPB) or polybutadiene acrylic acid acrylonitrile prepolymer (PBAN), powdered metal (typically aluminum ), and various burn rate catalysts.
