"... The reader may be surprised to learn that the ski ramp built at Pax River is based on the type used on the Invincible class aircraft carriers which is a little bit shorter (50ft) and slightly shallower (0.5º) than the ramp on Queen Elizabeth-class carriers. Sqn Ldr Edgell explained: “The Pax River ramp design process dates back to 2005 but, at the time, the Queen Elizabeth ramp profile was not known. Analysis conducted in 2005 showed we simply needed to use a ramp with a profile that allows us to stay just under the predicted F-35B ultimate loads and the Invincible-class ramp achieved this.”
Pax River’s ramp allows the test team to make adjustments for different profiles and encompass everything below the ultimate loads of the aircraft. “Though the verification of our models during phases 1 and 2 we can tweak the control laws to work off other types of ramp, none of which are the same,” said Sqn Ldr Edgell. When the aircraft comes off the end it is ballistic and accelerates to the fly away air speed, typically 10-20kts higher than launch speed, and therefore reduces ground roll...."
