propellant

(noun)

Fuel, oxidizer, reaction mass or mixture for one or more engines (especially internal combustion engines or jet engines) that is carried within a vehicle prior to use.

Examples of propellant in the following topics:

  • Particle Accelerator

    • A particle accelerator is a device that uses electromagnetic fields to propel charged particles to high speeds within well-defined beams.
    • A particle accelerator is a device that uses electromagnetic fields to propel charged particles to high speeds and to contain them in well-defined beams.
    • Despite the fact that most accelerators (with the exception of ion facilities) actually propel subatomic particles, the term persists in popular usage when referring to particle accelerators in general.

  • Opisthokonts: Animals and Fungi

    • One common characteristic of opisthokonts is that flagellate cells, such as most animal sperm and chytrid spores, propel themselves with a single posterior flagellum .
    • In contrast, flagellate cells in other eukaryote groups propel themselves with one or more anterior flagellae.

  • Flame Cells of Planaria and Nephridia of Worms

    • The cilia propel waste matter down the tubules and out of the body through excretory pores that open on the body surface; cilia also draw water from the interstitial fluid, allowing for filtration.
    • In the excretory system of the (a) planaria, cilia of flame cells propel waste through a tubule formed by a tube cell.

  • The First Law of Thermodynamics

    • For instance, when rocket fuel burns and causes a space shuttle to lift off from the ground, the chemical reaction, by propelling the rocket, is doing work by applying a force over a distance.
    • The powerful chemical reaction propelling the rocket lets off tremendous heat to the surroundings and does work on the surroundings (the rocket) as well.

  • Reducing the cost of pumps and pumping

    • In some cases, over-sized pumps can be balanced by trimming the impeller or replacing it with one of a smaller diameter (an impeller, which is similar to a propeller, transfers energy from a motor to the fluid being pumped inside a tube or pipe by directing, increasing and pressurizing the fl ow of liquid inside).

  • Nitrogen Compounds

    • This can propel a bullet out of a gun or cause a firework to explode.
    • These engines were extensively used on spacecraft such as the space shuttle and those of the Apollo Program because their propellants are liquids at room temperature and ignition occurs on contact without an ignition system, allowing many precisely controlled burns.

  • Orbital Maneuvers

    • This effect is the result of propellant having more usable energy (due to its kinetic energy on top of its chemical potential energy).
    • In orbital mechanics, a gravitational slingshot (or gravity assist maneuver) is the use of the relative movement and gravity of a planet or other celestial body to alter the path and speed of a spacecraft, typically in an effort to save propellant, time, and expense.

  • Personality Psychology

    • Personality psychology studies the long-standing traits and patterns that propel individuals to consistently think, feel, and behave in specific ways.
    • Personality refers to the long-standing traits and patterns that propel individuals to consistently think, feel, and behave in specific ways.

  • Television Debates

    • This would eventually help to propel Reagan to a landslide victory.
