Jean Claude, Thank you very much for the dialogue. You are keeping me on my toes and causing me to think a whole lot. Maybe some others can learn from our conversation also .
I agree with this if the center of gravity never moved. Center of drag may be another issue. The pusher will also be pushing against the cg and the center of drag which will always be dynamically moving and not in the center of thrust.
Fuel levels, cargo, person weight,people weight, etc. even the movement of passengers (albeit a small effect).Can you elaborate on your theory that the CG is dynamically moving?
Thank you. Pretty cool!Here you can see Jean Claude in person as well as a couple of photos of his wooden tractor gyroplane out of his workshop:
Small tractor gyroplane builded in wood
It seems even smaller outside the workshop Relief, I can nevertheless sit me in the cab Of course an asymmetrical tail stabilizer is provided to compensate the engine torque. Also two vertical surfaces.www.rotaryforum.com
There used to be more photos on the French Autogire site, cannot locate them now...
Also, few pictures here
Also, few pictures here
Jean Claude, I agree with you. Thank you for your input. You are very helpful. Are you able to share the spreadsheet? my email is [email protected]. Again, I appreciate you and respect your great knowledge.Designing a 2-seater tractor side by side is difficult, because the pitching balance needs to be kept with two heavy passengers as well as with light one
This means that the seats must be on the rotor thrust line.
In these conditions the rear airframe must be heavy enough to balance the weight of the engine. It's unfortunate for rise performance.
You can arrange the different masses in a spreadsheet to monitor the hanging angle during your design. As here:

It looks like you will have easy entry and exit to the cockpit but I think you need to triangulate more somehow between station 4 and 2.Here is a rough sketch of one concept I am working on. It is by no means finished. For an idea of scale, the length of the tube structure in the drawing is 12 feet.
