The diameter of the exhaust nozzle of jet engines

[royp]

Hello,

Can anybody please tell me the typical diameter of the exhaust nozzle of a jet engine? I know, there are different types of engines and nozzle types also vary. For instance, I am interested to know the typical diameter of the nozzle of a turbofan engine.

Thanks

That's a pretty vague question. However, a bit of Google searching found the JT9D engine used on some Airbus models has a nozzle diameter (judged by eye from a picture) around 1 meter.

Lots of good info and links in the Wikipedia article: https://en.wikipedia.org/wiki/Jet_engine

I would think it should be obvious that among other things the diameter will be a function of design thrust. So there is no one typical size.
