F-35 Navy Jet Confirms Carrier-Landing Strength Predictions

F-35 Navy Jet Confirms Carrier-Landing Strength Predictions: "A Lockheed Martin F-35C Lightning II carrier variant successfully completed testing in which it was dropped from heights of more than 11 feet during a series of simulated aircraft-carrier landings.
The tests validated predictions and will help confirm the F-35C's structural integrity for carrier operations.
The jet, a ground-test article known as CG-1, underwent drop testing at Vought Aircraft Industries in Grand Prairie, Texas. No load exceedances or structural issues were found at any of the drop conditions, and all drops were conducted at the maximum carrier landing weight.
The drop conditions included sink rates, or rates of descent, up to the maximum design value of 26.4 feet per second, as well as various angles and weight distributions. The tests were used to mimic the wide range of landing conditions expected in the fleet."
