In English, many things are named after a particular country – but have you ever wondered what those things are called in those countries?
1(rocket fuel)propergol masculine
- The maneuver is necessary, since onboard propellant is nearly depleted.
- When the propellants combine within the engine, they produce thrust.
- Perchlorate is a waterborne contaminant left over from propellants and rocket fuels.
- Most NASA spacecraft rely on some form of chemical propellant to push themselves through space.
- The end result is a total of 108 tonnes of methane/oxygen rocket propellant.
- Slower burning powders tend to deliver better accuracy than faster burning propellants, even when velocities are identical.
- A fixed amount of propellant is contained in the rocket motor.
- The extra propellant provides an additional 50 tonnes of thrust in the first 20 seconds following liftoff.
- A pedant or two might ask if you really mean rocket propellants when you say rocket fuel.
- They therefore deliver about ten times as much thrust per kilogram of propellant used, making them very ‘fuel-efficient’.
- Perchlorate is the primary ingredient of solid rocket propellant that is increasingly found in soil and water.
- To get to the Moon she expended only about 60 kilograms of xenon propellant.
- The first rockets used solid propellants, such as black powder, but they were very inefficient.
- He also theorized that liquid propellant made for a far more powerful and efficient fuel for rockets than solid propellant.
- Rocket propellants come in two parts, fuel and oxidizer, which work together to keep an engine burning.
- Most launch vehicles use liquid propellants, but some use motors with solid fuels.
- 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 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.
- The long-planned impact is necessary now that the onboard propellant is nearly depleted.
2(in aerosol)propelente masculine
- These substances, also known as freons, were once used extensively as coolant fluids in refrigerators and air conditioners, and as propellants in aerosol cans.
- This gas has long been used as a propellant in aerosol sprays and in refrigerators.
- The other thing our government needed to protect us from was the stuff used as propellant in aerosol cans.
- They include ether, chloroform and halothane; the ones that commonly cause addiction are ethyl alcohol, propellants in spray cans and petrol.
- These inhalers don't use a chemical propellant to push the medication out of the inhaler.
- 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.
- He explained that deodorants and other aerosols contain propellants, like butane, to dry the particles.
- Aerosol propellants contain flammable and nerve-damaging ingredients as well as tiny particles that can lodge in your lungs.
- Today, almost all aerosol cans contain alternative propellants, such as liquefied petroleum gas, which do not pose as serious a threat to the environment.
- 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.
- Chlorofluorocarbons were developed and used as refrigerants, blowing agents for polyurethane foam, and propellants in spray cans.
- For example, chlorofluorocarbons have been used in the second half of the 20th century as nonflammable refrigerants, industrial solvents, foaming agents, and aerosol propellants.
- They have uses as propellants in aerosol spray cans, refrigerant gases, and foaming agents for blown plastics.
- 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.
- 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.
- Alternatively, the aerosol container may be inverted allowing direct access to the propellant via the dip tube.
- In the 1970s, the United States, along with several other countries, banned the use of CFCs as aerosol propellants.
- Carbon dioxide is used to make carbonated beverages, in fire extinguishers, and as a propellant in aerosol products.
- These metal cans are capped with valves that seal the pressurized propellant in the can and control dispensing of the contents.
English has borrowed many of the following foreign expressions of parting, so you’ve probably encountered some of these ways to say goodbye in other languages.
