in this report they mention the Hiller Model-1031,and I don't know if it was derivative
of it or not ?

The designation "Model 1031" applied to all the successive variants of the Army's VZ-1E Pawnee flying platform for single soldier transport.

I don't believe it applied to the numerous multi-duct platform projects that Hiller designed after that.

Wingless device with swivel-mounted fan powered by a central engines


* the text label VTOL as perpendicular takeoff
 
Before I forget - thank you for posting the DTIC paper about the flying cranes. Very interesting read (well, it is to me.... ;) ).


Do I read the drawings correctly? Is there a propeller at the rear of both the 3 and 4 fan versions? If there is, one presumes it's to provide longitudinal thrust without tilting the whole airframe?


Thanks again.

Variable pitch on the fans for roll and pitch control and vanes in the efflux for yaw control.

Hi,

when I saw this drawing to that helicopter before,I thought it was a
hypothetical design,but it was not,here is a report about it with various
ducted-fan Projects.

I hope someone can make the drawing No.6 clear.
