propellantSubstance burned in a rocket for propulsion. With bipropellant, two propellants are used: oxidizer and fuel are stored in separate tanks and pumped independently into the combustion chamber. Liquid oxygen (oxidizer) and liquid hydrogen (fuel) are common propellants, used, for example, in the space shuttle main engines. The explosive charge that propels a projectile from a gun is also called a propellant. How to thank TFD for its existence?

The Mystic device delivers particles directly to the lungs with better than 90 percent efficiency, and without the need for liquid propellants or other pressurized systems. For example, Iraq had not given any evidence to support its claim concerning its production figures for indigenous warheads, and there were significant gaps in its accounting for such major components for operational missiles as guidance and control systems, liquid propellant fuels and ground support equipment. This is done to keep the tank's super-cold cargo -- 526,126 gallons of liquid propellant used to fire the shuttle's three main engines -- in a liquid state and to prevent icing. |
