Busy going through "Ace the Tech" and i'm not buying it's discription of WCF blades.
What are the advantages to Wide Chord Fan blades?
I Know the that they are stronger, and therefore handle FOD better, and also being thicker, they are less suseptable to vibration. But why would having a lower aspect ratio (Not mentioned in ACE) be such an advantage? I'm no aerodynamic expert, but i thought that the issue of aspect ratio was important to us when it comes to Induced drag, but surely this is not an issue here, after all, it's ducted!!
Would WCF's be capable of higher speeds? Or would it not need to as a wider chord would produce the required airflow at a lower speed.
I'm a bit lost
thanks
