No, it doesn't have to be. I agree that the forces involved are the same, however - you end up taking the same amount of veritcal forces and distributing it along less surface area. Even if your measurements are correct, you are looking at the same forces distributed along 238.64 square feet, versus 260.62 square feet.
I hate the fact the Osprey is replacing the Phrog for a very personal reason (I want to keep flying throughout my reserve career, and the Osprey is going to force us to move, leading to me not being able to drill here any more), but I can also see its limitations. EVERY Osprey guy is incapable of seeing its limitations. EVERY Osprey guy. I actually heard an Osprey guy (who, oh - by the way, had less hours, less combat hours, and less goggle hours than I did) tell me that the Osprey has "No limitations."
That attitude will kill people. I don't give a fuck how good your aircraft is.
Jesus, Clarence, lighten up.
I did acknowledge the rotorwash hits you harder, after all. It's not the hammer of the gods, though.
The Osprey is by no means a miracle aircraft. At the same time, some of the phrog phanatics are completely f-ing unhinged.
I've got about 1000 hours in each. I do know where the future lies, and which one brings more to the table.
The 46 had to go away, V-22 or no V-22. It is a mediocre performer even among medium-lift helicopters. Even in the FRS, IPs would sell it with phrases like, "It's the most manueverable helicopter in the world!" When I got to the fleet and learned how to read an E-M diagram, I could see that it's not even the most manueverable helo among really old helos.
The V-22 is a decent, but unexceptional, helo and a decent but unexceptional turboprop. It has significant shortcomings when viewed in isolation against either. It's the fact that it brings those two together that makes it capable.
Osprey types are somewhat insular and defensive for a reason. Every half-wit who's watched 60 Minutes thinks he's a freakin' aerospace engineer and tries to call it a POS. 46 guys who've barely seen one would have rabid opinions based on 4th-hand information. There's a certain mindset that does develop when every PEL hits the national press that's only now starting to abate.
