Solid propellants are classified as homogeneous and heterogeneous propellants homogeneous solid propellant is solid propellant or mixture of solid propellants thoroughly mixed in a colloidal state. Stabilizers and plasticizers are used to increase chemical stability and properties of propellant it is further classified as-.
William Anderson, in Encyclopedia of Energy, 2004. 3.3 Solid Propellants. The propellant in an SRM must burn at the proper rate to maintain the desired thrust profile and must have structural continuity to withstand the pressure and acceleration loads introduced during flight. Most physical characteristics cannot be predicted analytically, so heavy use of empirical data is required.
Typical illustrations of homogenous propellents are single-base (NC nitrocellulose) or double-base (NC and NG trinitroglycerin) propellents. In a heterogenous or composite propellent, the ingredients are physically assorted, taking to a heterogenous physical construction.
Solid propellant motors are the simplest of all rocket designs. They consist of a casing, usually steel, filled with a mixture of solid compounds (fuel and oxidizer) which burn at a rapid rate, expelling hot gases through nozzle to produce thrust. When ignited, a solid propellant burns from the centre towards the sides of the casing.

Two general types of solid propellants are in use. The first, the so called double-base propellant, consists of nitrocellulose and nitroglycerine, plus additives in small quantity. There is no separate fuel and oxidizer. The molecules are unstable, and upon ignition break apart and rearrange themselves, liberating large quantities of heat.Learn More
Don’t mix classification criteria. For instance, don’t write about freelance jobs and part-time jobs before talking about creative jobs. We’ve Got Your Back With Essay Examples.

A propellant or propellent is a chemical substance used in the production of energy or pressurized gas that is subsequently used to create movement of a fluid or to generate propulsion of a vehicle, projectile, or other object. Common propellants are energetic materials and consist of a fuel like gasoline, jet fuel, rocket fuel, and an oxidizer.Learn More

Variants include the retired Falcon 9 v1.0 and Falcon 9 v1.1, as well as the current Falcon 9 Full Thrust, both partially-reusable launch systems powered by rocket engines utilizing liquid oxygen (LOX) and rocket-grade kerosene (RP-1) propellants.Learn More
The characteristics of good propellant are as follows-. It should have specific impulse (thrust delivered divide by the rate of propellant burnt). It should produce low molecular weight.Learn More
Dry powder inhalers have been developed to generate a dry aerosol without using propellants. Most common classification of these devices refers to the kind of drug storage used. Some systems employ single drug capsules, which require refilling after every use, some devices contain several solely blistered single doses and others enclose a collective drug reservoir, from which single doses are.Learn More
Firearm investigation is a specialty of forensic science focusing on the examination of firearms and related subjects. Closely linked to this is ballistics, which relates to the flight path of projectiles, often associated with forensic science during the investigation of firearms.Learn More
