    • A pedant or two might ask if you really mean rocket propellants when you say rocket fuel.
    • A fixed amount of propellant is contained in the rocket motor.
    • They therefore deliver about ten times as much thrust per kilogram of propellant used, making them very ‘fuel-efficient’.
    • My husband was a research chemist working on propellants - a real rocket scientist.
    • More like rocket engines, jets produce thrust by burning propellant (jet fuel mixed with air) and forcing the rapidly expanding gases rearward.
    • The first rockets used solid propellants, such as black powder, but they were very inefficient.
    • The maneuver is necessary, since onboard propellant is nearly depleted.
    • The long-planned impact is necessary now that the onboard propellant is nearly depleted.
    • To get to the Moon she expended only about 60 kilograms of xenon propellant.
    • Perchlorate is the primary ingredient of solid rocket propellant that is increasingly found in soil and water.
    • Rocket propellants come in two parts, fuel and oxidizer, which work together to keep an engine burning.
    • When the propellants combine within the engine, they produce thrust.
    • The exhaust from an ion engine travels up to 10 times faster than does the exhaust from a chemical engine, generating far more thrust per pound of propellant.
    • Most launch vehicles use liquid propellants, but some use motors with solid fuels.
    • Perchlorate is a waterborne contaminant left over from propellants and rocket fuels.
    • The end result is a total of 108 tonnes of methane/oxygen rocket propellant.
    • The extra propellant provides an additional 50 tonnes of thrust in the first 20 seconds following liftoff.
    • He also theorized that liquid propellant made for a far more powerful and efficient fuel for rockets than solid propellant.
    • Slower burning powders tend to deliver better accuracy than faster burning propellants, even when velocities are identical.
    • Most NASA spacecraft rely on some form of chemical propellant to push themselves through space.

    (in aerosol)
    propelente masculino
    • Today, almost all aerosol cans contain alternative propellants, such as liquefied petroleum gas, which do not pose as serious a threat to the environment.
    • Carbon dioxide is used to make carbonated beverages, in fire extinguishers, and as a propellant in aerosol products.
    • These substances, also known as freons, were once used extensively as coolant fluids in refrigerators and air conditioners, and as propellants in aerosol cans.
    • The data on whether the majority of cancers, neurological problems, and other health problems are associated with exposure to fuels, propellants, or combustion products were inadequate to draw conclusions.
    • They include ether, chloroform and halothane; the ones that commonly cause addiction are ethyl alcohol, propellants in spray cans and petrol.
    • Alternatively, the aerosol container may be inverted allowing direct access to the propellant via the dip tube.
    • These inhalers don't use a chemical propellant to push the medication out of the inhaler.
    • He explained that deodorants and other aerosols contain propellants, like butane, to dry the particles.
    • In automobiles, for example, the thermal decomposition of sodium azide produces a large amount of nitrogen gas that acts as a propellant that causes air bags to open on impact.
    • These metal cans are capped with valves that seal the pressurized propellant in the can and control dispensing of the contents.
    • In the 1970s, the United States, along with several other countries, banned the use of CFCs as aerosol propellants.
    • Chlorofluorocarbons were developed and used as refrigerants, blowing agents for polyurethane foam, and propellants in spray cans.
    • CFCs had been used commercially as refrigerants since the 1930s, but because they were inert and non-poisonous they were soon used for many other applications, most notably as propellants in aerosol spray cans.
    • The other thing our government needed to protect us from was the stuff used as propellant in aerosol cans.
    • Aerosol propellants contain flammable and nerve-damaging ingredients as well as tiny particles that can lodge in your lungs.
    • For example, chlorofluorocarbons have been used in the second half of the 20th century as nonflammable refrigerants, industrial solvents, foaming agents, and aerosol propellants.
    • This gas has long been used as a propellant in aerosol sprays and in refrigerators.
    • By the mid-1970s, the United States government banned the use of CFCs as aerosol propellants but it resisted a total ban for all industries.
    • They have uses as propellants in aerosol spray cans, refrigerant gases, and foaming agents for blown plastics.
