- Hot_start abstract "In aviation, a hot start is an adverse effect of a reaction engine being improperly started.In a jet engine - be it a pure jet, a turbofan or a turboprop - a great amount of the air ingested by the engine runs around the combustion chamber or around its flame, instead of being mixed with fuel and burned. The purpose of this air is to keep the temperature of the chamber within its limits. If it weren't for this cooling effect, the chamber would get too hot because of the combustion, and it would then be burned or even melted.In a turbofan, the engine is started when compressed air is blown through its high-pressure stages. In a turboprop, the engine is started by the starter-generator, which is the engine's own electric generator - during the start, an electric current runs through it, making it spin, and then making the whole engine turn. In both cases, the engine must be already spinning before igniting the fuel, so as to have the compressors attain enough speed to draw air and make it flow though the engine. When there is a sufficient amount of air flowing, the fuel is injected, and then the engine will be able to run by itself.The critical part is injecting the fuel. If the fuel is ignited before there is enough air flowing around the chamber, its temperature will increase dramatically, which will cause severe damage to the chamber. This condition is known as a hot start.".
