If buzzwords are wrong, I don't want to be right.

I've heard talk about there being problems with the exhaust heating up decks...any word on this from osprey drivers?

I would think that the propwash would diffuse it. But that is my engineer hat, and not from actual experience with a V22

Wow, now I know. Old jokes aren't like scotch. They don't get better with age.

The deck heating is an issue, but not as big as some make it out to be. I'm not going to go out of my lane and claim to have read the test data, but you don't have to worry about destroying the LHD deck. A few liferafts on the sides of the flight deck, maybe. There is a system that deflects the exhaust to the sides when the Osprey is on deck. It still is hot enough to turn grass brown if you're on the deck for awhile, but as long as you're not visiting golf courses, you should be all right.

Roga...I've heard about a few problems with the Osprey being on the future LSC deck, but was just talk over beers.

Just saw a folded V-22 on the deck of the San Antonio yesterday...the future of littoral warfare right there.

214 is in the the the ballpark for cruise speed. Top end level flight is 30-50 knots higher depending on weight and conditions.

No droptanks. Weapon is currently a ramp gun with future improvements in the works.

What about the exhaust from the harriers? When the nozzles are vertical do they not heat up the deck like the osprey? The osprey EGT must be hotter right? I mean...since the harriers have been operating from amphib decks for years its seems that they would have already had a fix. Just curious anyhow..

I'd say the EGT of a Harrier is much higher than a V22. The gases from a V22are IR suppressed and deflected. I think the difference is that a Harrier chops power and moves its exhaust as soon as it's on deck, whereas an assault support aircraft will loiter on deck for an extended period.

Harrier exaust can be as high as 800 deg C, though normally not for long. We do tear the hell out of spot 7 as the cruise goes on, tearing up non-skid and fodding engines when the deck maintenance is delinquent. If the deck is kept in good shape, it's not a big problem. I've heard of JPT issues with the F-35, though.

Phrog is right that we go to idle and move the nozzles aft after landing. Our idle JPT is about 300-400 deg C.
