It looks like a nervous breakdown for a mechanic. And you'd neeneed a very trusting flight crew. Wonder if there is any vidvideo of this thing in flight

Is there any project related to this active now?

Perhaps an USAA mechanic manual of years gone by would go a long eat in understanding the flight concept.....?

My father E.B. Morris was a Vice-President for Kellett in 1949 I was taken to the Kellett facility in North Wales Pennsylvania to observe the XH-10 under construction and testing. In addition my father worked with a Czech engineer he was able to bring to Philadelphia after he was liberated by U.S. troops at the end of WW II . His last name was Kadenecy - he was forced to work on V-2 rocket engines by the Germans.

Think of the rotors as a set of gears with only 3 teeth each,each tooth going between the other as it turns,,,,,simple,use card board and draw a 3 bladed rotor X2 and cut them out ,hold them in each hand (thumb & index fingers) and hold then close and at an angle as seen in the picture,now turn them like gears,The blades will miss the others and turn on its own axis......

I aggre with jozef about the diagram i just dont get it

H. Wessels, e-mail, 03.08.2009 22:44

The rotors were synchronized via a cross-drive between the upper transmissions. If one engine failed, the remaining engine drove its own transmission as well as the opposite one, via the cross-drive.

ok im confused in the pictures it appears that the blades intersect. i know on your page it says that the motors were synchronized but i would think that if they were to the extent that the blades were interwoven that would be a characteristic more emphasized but you also state that it could run on one motor witch would not work if the blades did cross for obvious reasons. so i guess i would like an explanation or maybe a diagram witch better depicts the structural design of this machine.

thank you for your time,
