BAE Systems' Graham Tomlinson, lead test pilot for the F-35B STOVL JSF, says the aircraft "landed itself" after its June 11 conventional first flight. He contrasts this with his previous STOVL mount, the Harrier, where a conventional take-off is "not pretty" and a conventional landing is a "dire emergency".
Tomlinson says the first F-35B, aircraft BF-1, handles very similarly to the first CTOL F-35A, aircraft AA-1, which has been flying since the end of 2007. He notes a couple of improvements. BF-1 has two smaller nose-gear doors replacing the one-piece "barn door" on AA-1 that makes take-offs "directionally interesting". And refinements to the flight-control software make the touchdowns smoother.
BF-1 is the first production-representative, "weight-optimised" F-35, and internally is quite a bit different to AA-1. But externally, the differences are fairly limited. There are the nose gear doors and the thickened spine aft of the cockpit, looking like the over-muscled neck of a weightlifter, which accommodates the shaft-driven lift fan.
Tomlinson says BF-1 is fully configured for STOVL, and automatically checks out the lift system before flight, opening the doors and waggling the nozzle. But actual STOVL flight testing will not begin until the first quarter of 2009 because of engine issues. Lockheed says in-flight conversion tests will begin towards the end of this year with the doors being opened in flight. Early in 2009, BF-1 will begin "build-down" flight testing to a slow landing at Fort Worth, then relocate to the Navy's Pax River test center for the first full vertical landing.
