A bit of artwork from Bell showing a design for a VTOL cargolifter capable of carrying and delivering via hoist while hovering a standard rail-roadable cargo module. No further data. Likely dates from the early 1960’s.
The wind blast from those ducts would have made that railyard an interesting place.

Sorry, the comment form is closed at this time.
I have always been a fan of the X-22.
Huh. Just occurred to me that those appear to be high bypass turbofans rather than ducted propellers. 8-| I wonder if the designer has ever been to a rail yard before.
interesting projects
this VTOL on Railyard = Shrapnel wounds
by the way wat is better :
Ducted propeller or high bypass turbofans for this VTOL concept ?
It’s rarely clear what is *best.* Turbofans would be better for long distance, high-speed cruise. Ducted props would be better for hovering (and rotors, better still). So depending on just what your vehicle is going to do will determine what’s best.
In any event, the disk loading on this thing would be pretty high. I’d wonder about just how stable the payload would be, suspended like that amidst four impressive jet blasts.
