Bell Helicopter’s V-280 Valor tiltrotor prototype, developed to replace the U. S. Army’s UH-60 Black Hawk and AH-64 Apache helicopters, is scheduled to make its maiden flight before the end of 2017.
I can see the other V-280 benefits such as speed and range, but landing and doubling the probability of an engine malfunction, especially in combat conditions, I am having a hard time getting myself to accept. Commercially, OK.
Klindar, side note, I watched the big Russian cargo plane bring in the Kamov's KA-32's for Vancouver Island Helicopters in 1997. I watched C-FIGR going through its trials, I think it was trials, for a year or so after.
Now you have two engines exposed to gun fire as opposed to one enclosed by the air frame. Two counter rotating main props enclosed in the air frame, as in the Russian design, still make the most sense to me.
