Couple years ago BB56 showed me that one. Kind of cool, really ugly

The Germans built one as well. I think it was Lippisch.
The drag of the barrel like fuse overcame the efficiency of the ducted prop on the Caproni. Not sure how the Aerodyne faired but it had no wings.
Wot, no Depron?

Caproni designed a motorjet engine in the 1930`s and it flew in 1940.
A piston engine drove a turbine and the exhaust was set on fire to produce the jet.
If you are brave enough you could do this with a model plane. Jeff???????
The idea of a motor jet dates back to 1910 with a ducted prop with kerosene to burn the exhaust. It might have been an accident when the man experimenting with a ducted prop had a fuel leak that caught fire and produced the first jet engine
Gosh, I can`t remember the guy`s name but he was famous.

Fancy forgetting Coanda`s name
Just done some research and found the plane

So when it come `s down to the argument as to whether the Germans or British invented the Jet engine first, you can tell them it was a Romanian

It does raise the question when does an EDF become a ducted prop?
My Airbus A350 looks like an EDF.09Jun18.JPG 
But inside each scale Trent nacelle is a 3x3.5 4 blade prop!

To go back to Coanda. Was his plane really a turbo jet or an 'augmented' motor fan?
There is also some question as to whether it really 'flew' as such but it is nevertheless a tribute to the power he obtained from the motor and the design of his fan that in 1910 it achieved sufficient thrust to get the plane to a 'flying' speed.

that's an intresting one and not so ugly,how to be a test pilot in the early days of flight,rather them than me.

Apparently Coanda was a bit of a bullshiner, he claimed his piston powered what ever it was, was meant to be a jet but a witness said the plane caught fire and crashed.
Who in their right mind would sit in a hot jet stream?
I believe rightly or wrongly, Coanda accidentally invented the jet engine when his piston powered ducted fan caught fire
I certainly don`t know enough to get into a debate about it and I don`t think anyone else but Coanda did
But what ever happened to Coanda sowed the seeds for the jet engine.

Too true, Andy.
It is a very sleek looking plane even if it was not a success.
