what are the differences between a turboprop and jetprop

[jamestkirk]

Hello.

Do any of you know the actual differences between a turboprop and jetprop.

I have searched in vain on many websites but have not found a definative answer.

Thanks

2 ways of saying the same thing. Turboprop is the most common.

Unless someone knows better.

On this site, there is always someone that knows better, it is that sort of rumour network!

There is no difference. They are both Gas Turbine Engines driving a gearbox, which in turn drives a propellor.

JetProp sounds so much more exciting to the marketing dept.

I can see you are a man of truth

Jamestkirk, probably someone calls JetProp what should be called PropFan. In this case there's a big difference.

Propjet tended to be a term used by manufacturers in the US when the first turbo props were introduced. The term propjet was used long before the experimental propfan emerged.

Rigpiggy is probably correct in that it stems from the marketing departments.
The Electra was commonly referred to as a propjet and this aircraft was not succesful in the passenger market because it was an advanced (for its era) turboprop that was introduced as turbojets were becoming popular.
