|Quoting N231YE (Thread starter):|
Probably a fair amount of lobbying from the Osprey crowd of the "Special Interest" machine that is the defense industry, too. Too similar, too cheap, too threatening to the cash-rich money pit that the V-22 promised it could be...
Probably no connection whatsoever. The X wing was a basic research aircraft that was cancelled right about the time the V-22 hit FSD
; maybe even a year or two earlier. Notably, it did not ever attempt a conversion between flight modes. I'm not even sure that it ever flew with power to the rotors for that matter.
Also, since the X wing money was coming from NASA vs primarily USMC
for V-22 it's even more doubtful. PX
Kelly and his predecessor were powerful and influential but I don't think their reach extended to NASA by any means. It certainly wasn't because Dick Cheney was a big fan of the V-22 either.
Beyond this, the X wing technology had not even been demonstrated, much less matured at this time; even now two decades later the aerodynamics required have not been demonstrated in practice. In contrast, the tilt-rotor concept had been studied extensively and successfully over the better part of two decades with the XV-3 and XV-15. Boeing had also demonstrated use of a composite rotorcraft airframe with the Model 360 and was at the time at least 5-10 years ahead of Sikorsky in rotor blade technology.
Another important factor to consider is the CH
-53. Remember, the V-22 began just a few years after the Desert One debacle and at the time promised to eliminate some very big problems in Marine aviation exemplified by what happened during the failed hostage rescue attempt. Sikorsky could have proposed a larger X wing but this would have magnified the technical risk even more; it would also have been an implicit admission that the CH
-53 wasn't up to this type of mission. The reality is that they reasonably did not attempt this and instead pursued(unsuccessfully) the X wing as a funded research project and improved versions of the CH
Unfortunately a combination of over ambitious requirements, poor program management, schizoid funding, and serious problems from unexpected areas like hydraulics put it about a decade and a half behind where it was originally expected and obviously much over the original budget.
One good thing you can say for the X wing was that it looked really cool on the cover of Popular Science as a painting.
