F-35 Pax River ITF expands expeditionary envelope for USMC
22 Jan 2018 PEO(JSF) Integrated Test Facility Public Affairs

"...The capability inherent in a STOVL jet allows the Marine Corps to operate in harsh conditions and from remote locations where few airfields are available for conventional aircraft—from abandoned or primitive runways, to long stretches of roadways. The aircraft can also operate from sites where Marines construct their own expeditionary runway or landing pads with AM-2 matting, similar to that used during the sloped surface testing.

Through a series of vertical landing maneuvers in simulated expeditionary conditions, the team’s end goal will ease current sloped surface vertical landing requirements for the F-35B.

“We hope to be able to relax the landing pad certification limits in terms of maximum slope/gradients in the context of expeditionary pads—existing and future,” said Bob Nantz, F-35 Pax River ITF Performance/Environmental Technical Specialist.

With Marines from the 2nd Marine Aircraft Wing capturing real-time lessons learned, some of the test results will be instantaneous. However much of the data will require significant analysis before any updates can be made to the fleet, Lippert said.

The Pax River ITF will analyze nearly 200 data test points to assess how well the F-35B operates on varying slopes, impacts of head and tailwinds, and the effect of aft center of gravity in conjunction with ground slopes.

“These updates will eventually make it to our fleet aircraft while the capabilities of the F-35 will continue to transform the way we fight and win,” Lippert said....

...Marines from the 2nd MAW staged the Bogue testing site for the Pax River ITF team by constructing sloped landing pads with AM-2 matting, the same matting Marines use to build airfields nearly anywhere around the world. Second MAW squadrons provide aviation ground support, enabling Marine Aircraft Groups to conduct expeditionary operations.

“Every opportunity that we get as a Marine Wing Support Squadron to provide aviation ground support is a highly valued opportunity,” said Gunnery Sgt. Julio Silva, Marine Wing Support Squadron 274 Expeditionary Airfield Services chief. “The information gained will not only help the JSF but will also ensure that the expeditionary airfield capability is enhanced as we welcome the Marine Corps’ newest generation of aircraft into fold.”

With the sloped surface tests, the F-35 Patuxent River Integrated Test Force team wraps up testing of the F-35B short takeoff/vertical landing envelope, bringing it one step closer to initial operational test and evaluation. Through a series of vertical landing maneuvers in simulated expeditionary conditions, the team's end goal is to expand warfighter capability for the F-35B, allowing vertical landings with relaxed sloped surface requirements.

Has it got twin overhead go fast stripes now? Or is that another LoonyTunesLens? I'll get a shot of screen. I like the slomo.

Nice short takeoff. Go Here: https://www.dvidshub.net/search?q=F-35B+Bogue&view=grid

That hover at 2:49 is uncanny! Almost completely motionless.

F-35B Hover Test Record is 10 minutes. At roughly 400 lbs/min you do the math. I'm wondering what min fuel for landing was then. It was a test with a test pilot over the test VL pad at NAS Patuxent Field so he was RIGHT THERE! :mrgreen: :roll:

Hey Spaz, where'd you get 400ppm for hover fuel burn? Elsewhere's in this here forum? Do you know what the fuel burn is in MAX (blower on, but STOVL mode 4 OFF)?

ETA: My forum search-fu has failed me. I was not able to find a fuel burn rate or consumption rate of a Bee in STOVL / mode 4 esp. regarding a VL / hover.

Take an F-16, stir in A-7, dollop of F-117, gob of F-22, dash of F/A-18, sprinkle with AV-8B, stir well + bake. Whaddya get? F-35.

Yeah - was just reading that 400 the other day in the big 4.4Gb PDF but I'll dig it out. It is easy enough to predict the fuel flow because - usually - altitude is known - a ship at sea with other variables of course. Remember VLs are likely only to be done on a flat deck or for practice on a VL pad. Otherwise numbers of other 'non-VL' landings are carried out <sigh>.

Lockheed: Many F-35B landings won't be vertical 07 Jun 2011
http://www.dodbuzz.com/2011/06/07/lockh ... -vertical/

Probably somewhere there is a guesstimate about max burner fuel flow but at what altitude etc? Variables variables variables.

"...When we are in the STOVL mode we are burning a lot of fuel, around 400 lbs per minute and typically so when we land we will have around 3,000-4,000 lbs remaining.”

“The F-35B puts out 40,000 lbs of vertical thrust depending on the temperature and pressure altitude. Its zero fuel weight is around 34,000 lbs with a 6,000 lb margin for fuel and or stores. You have to get down to that weight before a vertical landing. But the great benefit of the F-35B is the vertical landing for small carriers...."

....you know there has to be "one" Marine who has fried an egg on that matting, due to the "blow torch" effect.....maybe even some bacon slices!!!!....where's the videos??

This forum thread may have useful info - I'm not reading it myself: F-135 or F-136 fuel burn rate
viewtopic.php?t=11567 THE NEXT QUOTE BELOW is from the current USAF F-16 DEMO PILOT.
"...profile lasts only 15min, but during that time I burn 6,000lb of fuel pulling 9g upwards of 15 times. Not to mention most of my flying occurs between 200ft and 500ft above ground level, at speeds ranging from 125kt to 620kt...." https://www.flightglobal.com/news/artic ... ex-444626/

The JB CLAWs do a pretty good job. BZ to the flight controls and flight test team...

It's always cool to see the B fly. Probably the most impressive variant.
