    Combustion and Ignition of Nitramine Propellants: Aspects

    Ignition of solid propellants and explosives involves an array of intricate physiochemical processes under energetic stimuli, and has been a subject of extensive research since 1950. In general, ignition models can be broadly divided into four categories: solid-phase (or reactive . 9 solid), heterogeneous, gas-phase, and multi-phase reaction models. The solid-phase reaction models52-55 assume

    Propellant

    Solid propellants are used in forms called grains. A grain is any individual particle of propellant regardless of the size or shape. The shape and size of a propellant grain determines the burn time, amount of gas, and rate produced from the burning propellant and, as a consequence, thrust vs time profile. There are three types of burns that can be achieved with different grains. Progressive

    In most liquid-propellant rocket engines, a fuel and an oxidizer (for example, gasoline and liquid oxygen) are pumped into a combustion chamber. There they burn to create a high-pressure and high-velocity stream of hot gases. These gases flow through a nozzle that accelerates them further (5,000 to 10,000 mph exit velocities being typical), and then they leave the engine. The following highly
