Mart,
The concept definitely has pros and cons, but so far - so good.
Some quick replies.
the machine magically appears from hover to cruise state.
Yes, transition is currently the primary concern. Here are
Seven preliminary ideas for effecting the transition.
I still think that if you want the best transition performance you need a low front rotor and high rear rotor, to avoid interference effects. .... Even so, the penalty of carrying those wings around in hover will be high.
The V-22 looses 10% of its thrust in hover due to its downwash on the wings (Leishman and one other). This 2x4 PropRotor only places a downwash on the wings during transition and the downwash will not be normal to the flat-plate surface of the wings.
Keeping the rotor/prop hubs at the same position in space will also simplify the drive-train.
The drive-train consists of four independant PropRotor+Motor, with a liberal sprinkling of electronic SAS.
Theoretically the
2x4 Effective Aerodynamic Disk Area should give a better hover AND a faster cruise than the current V-22.
A testimonial;
"This is actually a very good idea. It is one of the most cleaver solutions I have seen yet. You have actually had me looking at your idea for about 20 minutes now." ~ Dennis Fetters.
Mart, Any ideas for a good transition mechanism?
