RC Jet EnginesStuff That You Always Wanted To Know About These Powerful GizmosCaution: RC Jet Engines are extremely dangerous in untrained hands. Please do not go for it if you are a beginner flyer or rc hobbyist. These can not only be dangerous for you but for your neighbours and fellow localites. Jet engines are for extremely experienced flyers only. If you are trying jet engines then request you to do so at the supervision of an experienced and skilful flyer. Radio control jet engines shot in the popularity chart very recently. Before their advent rc airplane flyers did not have any experience of the kind of power and speed that these engines are capable of. Now you must be wondering why I discuss about jet engines on this site which is dedicated to rc cars. Some time back I came across an article where a radio control car was modified to use a jet engine. You know techno freaks do this kind of stuff every now and then. One thing that got me hooked was the novelty of the idea and the power that the engine generated to propel the car. I thought this might interest fellow rc car enthusiasts here and thus this article on rc jet engines. Working of RC Jet EnginesMost of the hobby jet engines used today is centrifugal flow turbine engines. Let’s see what that means and how it works in detail. The design of the jet engine is such that the air passing through the input runs over an impellor. The rotating impellor hits the air towards the inner edge of the turbine. This action increases the kinetic energy of the air. This results in an increase of temperature as well. Then this compressed air passes on to the combustion chamber. In the combustion chamber fine spray of fuel (Kerosene) is injected which mixes easily with the compressed air. Then the glow plug ignites the mixture. Once ignited the volume of the mixture grows exponentially. Then this gas is forced out through the narrowing exit at great pressure. This generates a tremendous amount of thrust in the forward direction causing the rc airplane to move a unbelievable speed. Popular RC Jet EnginesHere is a partial list of popular radio controlled jet engines available in the market.
As I have said earlier jet engines are a lot more than toys. So if you are not an experienced flyer then this is just not for you. It’s dangerous, very expensive and very unforgiving.
