I was reading through "The Jet Engine" published by Rolls Royce and came across an interesting mechanical arrangement for a gas turbine engine called the Contra-Rotating Fan.
I was hoping that I could get some of my nagging questions answered about this rather unique looking engine:
- What was this proposed engines advantages?
- Why did it never get past the concept phase?
- Was it the weirdest looking gas turbine engine ever?
Any help would be much appreciated.
Thank you in advance.
