Hover–Pit Ground Tests Validate Propulsion System and Aircraft Response
FORT WORTH, Texas, April 23rd, 2009 --
The F-35B Lightning II short takeoff/vertical landing (STOVL) variant has demonstrated during testing that it produces excess vertical thrust – more than required to carry out its missions. The tests, conducted on a specially instrumented “hover pit,” also validated the performance of aircraft software, controls, thermal management, STOVL-system hardware and other systems.
“The performance level measured was absolutely exceptional,” said J.D. McFarlan, Lockheed Martin F-35 Air Vehicle lead. “We demonstrated 41,100 pounds of vertical thrust against our requirement of 40,550 pounds.This means we will deliver excellent margin for the vertical landing and short takeoff performance we’ve committed to our STOVL customers,” he said. Those customers include the U.S. Marine Corps, the United Kingdom’s Royal Navy and Royal Air Force, and the Italian Navy and Air Force.
