ARS (rocket Family)
The ARS rocket family was a series of rockets developed by the American Interplanetary Society — later the American Rocket Society — during the 1930s. Based on the German Mirak rocket, it used a liquid-fueled rocket engine, powered by liquid oxygen and gasoline propellant A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or other motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the e ...s. The first successful launch, of the ARS-2, took place on May 14, 1933. The design was modified and refined by successive rockets; the last launch of an ARS rocket took place on May 9, 1937. References Experimental rockets of the United States {{rocket-stub ...

American Interplanetary Society
The American Rocket Society (ARS) began its existence on , under the name of the American Interplanetary Society. It was founded by science fiction writers George Edward Pendray, G. Edward Pendray, David Lasser, Laurence Manning, Nat Schachner, Nathan Schachner, and others. Pendray corresponded with Willy Ley of the German rocket society, Verein für Raumschiffahrt, and visited him in 1931. The members originally conducted their own rocket experiments in New York and New Jersey. The society printed its own journal. The AIS did pioneering work in testing the design requirements of liquid-fueled rockets, with a number of successful test launches of ARS (rocket family), ARS rockets occurring in this period and pointing the way to the United States space program. Its name was changed to American Rocket Society on . In 1936, the American Rocket Society and its member Alfred Africano were awarded the Robert Esnault-Pelterie#Prix REP-Hirsch, Prix d'Astronautique by the Société astronomiq ...

Liquid Oxygen
Liquid oxygen—abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries—is the liquid form of molecular oxygen. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which has continued to the present. Physical properties Liquid oxygen has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of , slightly denser than liquid water, and is cryogenic with a freezing point of and a boiling point of at . Liquid oxygen has an expansion ratio of 1:861 under and , and because of this, it is used in some commercial and military aircraft as a transportable source of breathing oxygen. Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades.

Propellant
A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or other motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine. Although technically a propellant is the reaction mass used to create thrust, the term "propellant" is often used to describe a substance which is contains both the reaction mass and the fuel that holds the energy used to accelerate the reaction mass. For example, the term "propellant" is often used in chemical rocket design to describe a combined fuel/propellant, although the propellants should not be confused with the fuel that is used by an engine to produce the energy that expels the propellant. Even though the byproducts of substances used as fuel are also often used as a reaction mass to create the thrust, such as with a chemical rocket engine, propellant and fuel are two ...
