The secrets of Turboprops. .
Propeller driven aircraft have golden history. The greatest dream of mankind to fly like a bird was fulfilled by propeller driven engines only. In Earlier days, almost all the aircraft' s were propelled by the piston engines until turbine engines were developed. When the jet engines were invented, it brought a new age of aviation, called the jet age! The combination of propeller and jet engines were named as 'Turboprop'. Still, there are many airlines in the world who have their entire fleet of turboprop e. g. Truejet. In older days, flying in a propeller driven aircraft was much challenging job because of their message vibration and sound. But as technology progresses, the state of art systems improve the engine noise and vibration level so that passengers can feel more comfortable during the flight. This situation could get very critical when flying over long range. Bombardier Q400 have an artificial noise inducer, which produces a similar pattern of noise within the ca
