Durchschnittliche Drehzahl einer Strahltriebwerk: Vergleich mit einem Automobil

If you drive something a little spicier and higher-strung like a Honda S2000, 9,000 rpm might be the limit, whereas a motorcycle or an F1 car might reach 15,000 rpm. How do those rotational speeds compare to a jet engine's?

Technik und Auswirkungen

Well, the answer isn't all that clear-cut, because there are many spinning parts in your average modern turbofan engine, mainly the high-pressure and low-pressure turbines.

Even for those components, the actual rotating speed isn't too far off from a car, with the maximum speed of a high-pressure turbine reaching 15,183 rpm in the CFM 56 series of airliner engines. High speed and low speed Jomica8/Shutterstock The CFM 56 series of engines is the best selling jet engine ever.

It powers mass-market airliners like variants of the Boeing 737. The 56-7 variant puts out a maximum of 27,300 pounds of thrust. There is no direct translation from thrust to horsepower, but given a Boeing 737's cruising speed of over 500 miles per hour, it's safe to say it's more powerful than a car engine.

Einordnung fuer Autofahrer

Going into specific speeds, according to CFM and Stanford University, the maximum rpm of the CFM 56 is broken up into the high-pressure turbine speed and the low-pressure turbine speed. As mentioned earlier, the high-pressure turbine redlines at 15,183 rpm. The low-pressure turbine redlines at a slower speed of 5,380 rpm.

Those two speeds put a jet engines maximum rpm near the absolute pinnacle of F1 cars and the low speed somewhere near that of a commuter sedan.
