High bypass turbofan jet engines & contrails
WebTurbofan engines are common in GA aircraft. While most of these are business jets, recently a few new small jets powered by turbofans have emerged. Among such jets is the emergence of the personal jet, a new class of aircraft designed to be owner-flown and operated, analogous to single engine piston aircraft.This trend has led to the … WebThe increasing trend toward high-bypass-ratio turbofan engines has resulted in larger diameter fan cases. For example, the former GE 5:3 bypass ratio fan cases CF6-80C2 accounted for about 20% of the total engine weight, whereas the more recent 9:5 bypass ratio GEnx-1B represents a weight ratio of 33%. The use of PMCs can reduce the weight …

In a turbofan, only a part of the gas horsepower generated by the core is extracted to drive a propulsor, which usually consists of a single low-pressure …
WebOn modern turbojets the bypass air provides (at least) two things. Thrust. The air does bypass the engine core, but it is accelerated by the N1 fan and provides thrust as it is expelled rearward out of the engine. Thrust from the bypass air can contribute more than half of the total thrust produced by the engine (upwards of 80% of the total ... WebPeople - look at the sky pics - it's not normal like that!
