All in good fun.
Nick you're doing it again. You've got to put that bottle down.
Your strong support of the tail-rotor configuration would have made Igor proud. I hope you didn't hurt your neck a year ago when you did the quick about-face and started to champion the coaxial configuration.
Rebuttal comments;
!) We have had this discussion before. Virtually all of nature's creatures have lateral symmetry in respect to interaction with their environment. Virtually all of mankind's vehicles have lateral symmetry in respect to interaction with their environment. Are you saying that Darwin's evolutionary survival of the fittest is wrong? When you mention aerodynamics, are you saying that birds and airplanes have no reason for lateral symmetry?
2) What thread have you been reading? Mart said,
"Interesting that top rotor diam is NOW smaller than lower rotor." Are you suggesting that I should not believe it when Mart says that Sikorsky has changed the rotor diameter?
3) You said;
"There is little similarity between the ABC/X2 and any other coax or syncropter," Not so fast Quick Draw. There is much similarity between the
ABC/X2 and the
XH-59A ABC. Just think where the helicopter industry would be today if Sikorsky had taken that 1965 study, the subsequent XH-59A craft, plus the concluding recommendations; and then continued to improve and produce the coaxial configuration.
