It sometimes could be found on Luftwaffe aircraft also fitted with another engine-boost system, MW 50, a form of water injection for aviation engines that used methanol for its boost capabilities.Make A Nitrous Cracker Whipped Cream Chargers Nitrous Oxide Cartridge Jump to navigationJump to search Not to be confused with nitric oxide (formula NO), nitrogen dioxide ( NO 2 ), or generic nitrogen oxide pollutants NOx.At room temperature, it is a colourless non-flammablegas, with a slight metallic scent and taste.At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen.It is soluble in water.
Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and pain reducing effects. ![]() It is on the World Health Organizations List of Essential Medicines, the most effective and safe medicines needed in a health system. Nitrous oxide occurs in small amounts in the atmosphere, but recently has been found to be a major scavenger of stratospheric ozone, with an impact comparable to that of CFCs. It is estimated that 30 of the N 2 O in the atmosphere is the result of human activity, chiefly agriculture. Uses 2 Safety 3 Mechanism of action 5 History 6 Production 7 Atmospheric occurrence 8 Environmental impact Uses edit Rocket motors edit Nitrous oxide may be used as an oxidiser in a rocket motor. This is advantageous over other oxidisers in that it is much less toxic, and due to its stability at room temperature is also easier to store and relatively safe to carry on a flight. As a secondary benefit, it may be decomposed readily to form breathing air. Its high density and low storage pressure (when maintained at low temperature) enable it to be highly competitive with stored high-pressure gas systems. Nitrous oxide has been the oxidiser of choice in several hybrid rocket designs (using solid fuel with a liquid or gaseous oxidiser). The combination of nitrous oxide with hydroxyl-terminated polybutadiene fuel has been used by SpaceShipOne and others. It also is notably used in amateur and high power rocketry with various plastics as the fuel. In the presence of a heated catalyst, N 2 O will decompose exothermically into nitrogen and oxygen, at a temperature of approximately 1,070 F (577 C). Because of the large heat release, the catalytic action rapidly becomes secondary, as thermal autodecomposition becomes dominant. In a vacuum thruster, this may provide a monopropellant specific impulse ( I sp ) of as much as 180 s. While noticeably less than the I sp available from hydrazine thrusters (monopropellant or bipropellant with dinitrogen tetroxide), the decreased toxicity makes nitrous oxide an option worth investigating. Nitrous oxide is said to deflagrate at approximately 600 C (1,112 F) at a pressure of 309 psi (21 atmospheres). At 600 psi, for example, the required ignition energy is only 6 joules, whereas N 2 O at 130 psi a 2,500-joule ignition energy input is insufficient. Internal combustion engine edit Main article: Nitrous oxide engine In vehicle racing, nitrous oxide (often referred to as just nitrous) allows the engine to burn more fuel by providing more oxygen than air alone, resulting in a more powerful combustion. Therefore, it often is mixed with another fuel that is easier to deflagrate. Nitrous oxide is a strong oxidising agent, roughly equivalent to hydrogen peroxide, and much stronger than oxygen gas. Nitrous oxide is stored as a compressed liquid; the evaporation and expansion of liquid nitrous oxide in the intake manifold causes a large drop in intake charge temperature, resulting in a denser charge, further allowing more airfuel mixture to enter the cylinder. Sometimes nitrous oxide is injected into (or prior to) the intake manifold, whereas other systems directly inject, right before the cylinder (direct port injection) to increase power. The technique was used during World War II by Luftwaffe aircraft with the GM-1 system to boost the power output of aircraft engines. Originally meant to provide the Luftwaffe standard aircraft with superior high-altitude performance, technological considerations limited its use to extremely high altitudes. Accordingly, it was only used by specialised planes such as high-altitude reconnaissance aircraft, high-speed bombers and high-altitude interceptor aircraft.
