The carrier variant of the F-35 fighter and the V-22 tilt-rotor helicopter both present an unexpected problem to carrier crews: the risk of melting the deck. The heat of the exhaust on both of these aircraft can cause damage to the carrier’s deck if they are left running for more than a short period of time. Strategy Page reports:
The navy sought a solution that would not require extensive modification of current carrier decks. This includes a lot of decks, both the eleven large carriers, and the ten smaller LHAs and LHDs. This began looking like another multi-billion dollar “oops” moment, as the melting deck problem was never brought up during the long development of either aircraft. Previously, the Harrier was the only aircraft to put serious amounts of heat on the carrier deck, but not enough to do damage. But when you compare the Harrier engine with those on the V-22 and F-35B, you can easily see that there is a lot more heat coming out of the two more recent aircraft. Someone should have done the math before it became a real problem.
The solution to the V-22 heat issue is pretty straightforward: put heat-resistant pads under the exhausts, but the F-35 requires a (hopefully minor) redesign of the exhaust nozzles to diffuse the heat.
