Who was the first scientist to use liquid propellants?
Robert H. Goddard is considered the first scientist to successfully launch a liquid-fueled rocket in 1926. He used a combination of liquid oxygen and gasoline as propellants in his rocket experiments.
Why are grains used in ballistics?
Grains is the unit of mass of the projectile and the propellants.
What was one of the first propellants?
0N SEPTEMBER 18 0F THE yEAR 1785.
What else was gunpowder used for other than weapons?
mining and propellants in weapons
Who use cfc?
They are banned now most places-they were used as propellants for aerosols
What is mixture ratio of Rocket Propellants?
The mixture ratio of rocket propellants refers to the ratio of oxidizer to fuel in a rocket engine. It is an important parameter that determines the performance and efficiency of the engine. The specific mixture ratio can vary depending on the type of propellants used and the design requirements of the rocket.
What was one of the first propellant used for?
One of the first propellants used for rockets was gunpowder, which dates back to ancient China. Gunpowder, a mixture of sulfur, charcoal, and potassium nitrate, provided the explosive force needed to propel early rockets.
Who invented propellants for nuclear reactor?
As asked this question has no answer, as there are no propellants in nuclear reactors.
What did Donald Cotton invent?
Donald Cotton was known for his invention of propellants for nuclear reactors. His invention is used all over the world currently.
Is CFCs used in spray?
CFCs (chlorofluorocarbons) were once commonly used as propellants in spray cans, but they have since been phased out due to their harmful effect on the ozone layer. In response, many companies have transitioned to using alternative propellants that are more environmentally friendly.
What is the name of a chemical compound once used as a propellant in aerosol spray?
Prior to 1989, trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12) were the most used chemical compounds in aerosol-spray propellants. Their use was discontinued under the Montreal Protocol.
What kind of fuel used to propel a rocket in to space?
Rockets are propelled into space using liquid or solid propellants. Liquid propellants typically consist of liquid oxygen or hydrogen as the oxidizer and a fuel such as liquid hydrogen or kerosene. Solid propellants are a mixture of fuel and oxidizer that are combined into a solid form.
