The reason this is desired is because the thrust line doesn't change when an engine is lost.
First, do some reading, e.g., http://hdl.handle.net/2060/19940005945 and
For the lightly-loaded props used on homebuilts, the aerodynamic advantages are likely illusory and the mechanical complications excessive.
Thanks. I'm planning to use belts instead of gears. The test data on coaxial propellers was good information. I appreciate your time.
-multi V-belt gear is a good dampfer...
=we want to change 2-stroke G-25 motor to the speedway engine JAWA 250 (24 kg, >40 HP...),
of course,with CR differential gear !
-great problem=battery weight and costs...
=motor (diesel)/ synchonous generator(EMRAX) +two synchronous
electromotors (f.e. EMRAX) +ONE controller (for rear motor),
may be today solution as hybrid power system
(only little kWh from battery !)
