F-35B completes first airborne engine start tests

F-35B test aircraft BF-3, flown by Lockheed Martin test pilot Dan Levin, completed the first aerial weapons release for any variant of the aircraft. BF-3 dropped an inert 1,000-pound GBU-32 Joint Direct Attack Munition over an Atlantic Ocean test range from an internal weapons bay. The F-35B is the variant of the Joint Strike Fighter designed for use by U.S. Marine Corps, as well as F-35 international partners in the United Kingdom and Italy. The F-35B is capable of short take-offs and vertical landings to enable air power projection from amphibious ships, ski-jump aircraft carriers and expeditionary airfields. The F-35B is undergoing test and evaluation at NAS Patuxent River, Md., and Edwards Air Force Base, Calif., before delivery to the fleet.

The F-35 integrated test force announced the completion of a major prerequisite test for in-flight performance on the short take-off and vertical landing variant of the F-35 Lightning II Joint Strike Fighter Sept. 4 at Edwards Air Force Base, Calif.

BF-2 completed the first air starts, which test the ability of the F-35′s propulsion system to restart during flight. Verifying the restart capability of the propulsion system is part of the initial flight test program for the F-35 and a prerequisite for high angle-of-attack testing, scheduled to start next year.

“High alpha, or angle-of-attack tests, are important for us to fully evaluate the aircraft’s handling characteristics and war fighting capability,” said Marine Corps test pilot Lt. Col. Matthew Kelly. “Maximizing the performance of the airplane around the very slow edges of the flight envelope is probably some of the most challenging testing we will conduct. After we get through it, we’ll know a lot more about how this aircraft will perform during combat within visual range.”

Using multiple restart methods during the tests, BF-2 successfully completed a series of 27 air starts at various altitudes Aug. 15.

To execute air start testing, the F-35 Integrated Test Force at Naval Air Station Patuxent River, Md., ferried BF-2 and an F/A-18 chase aircraft from Air Test and Evaluation Squadron 23 to the F-35A testing facility at Edwards AFB.

“At Edwards, we have a unique testing range, which provides ideal and controlled conditions for completing air start testing. The Edwards range is comprised of 20,000 square miles of airspace, and has 65 linear miles of useable landing area on Rogers and Rosamond Dry Lakes, if required during engine out testing,” said Lt. Col. George N. Schwartz, commander of the 461st Flight Test Squadron and government site director. “In addition, we’ve recently completed air start testing on the F-35A, so we’re able to share some of our expertise with the Pax team as well.”

Lockheed Martin test pilot Dan Canin flies BF-2 during air start testing over Edwards Air Force Base Aug. 8. Air starts test the ability of the F-35′s propulsion system to restart during flight. Verifying the restart capability of the propulsion system is part of the initial flight test program for the F-35 and a prerequisite for high angle-of-attack testing. The F-35B is the variant of the Joint Strike Fighter designed for use by U.S. Marine Corps, as well as F-35 international partners in the United Kingdom and Italy. The F-35B is capable of short take-offs and vertical landings to provide air power from amphibious ships, ski jump aircraft carriers and expeditionary airfields. The F-35B is now undergoing test and evaluation at NAS Patuxent River prior to delivery to the fleet.

The core of the F-35B’s propulsion system is the F135 engine, capable of more than 40,000 pounds of thrust.

“The F135 continues to power a successful flight test program,” said Roy Hauck, Pratt & Whitney site lead at the F-35 Patuxent River ITF. “The aircraft and its integrated systems demonstrated intentional flameout and successful recovery scenarios during air start flight tests, and BF-2 and the team did a great job.”

A team of approximately 60 ITF and VX-23 personnel provided engineering and maintenance requirements for the events.

The detachment to Edwards from NAS Patuxent River overlapped with a busy summer flight testing schedule.

“In the past two months, we’ve sent detachments to Edwards and Lakehurst [N.J.], and maintained a full-tempo test schedule here,” said Navy Capt. Erik Etz, director of test for F-35 naval variants at NAS Patuxent River. “The team of military, government and industry personnel rallied to make all the events happen, and they can be proud of their accomplishments.”
