Forum: General F-35 Forum

@ Deadseal, almost every part of a UH-1 is replaceable so in theory they could fly forever. In an airplane like the F-16 it is cracks in the forgings that eventually kill the airplane.

And a new one... heat and vibration in the weapons bays pushing ordnance to the limits...

I realize that this new fangled weapons bay concept is hard to conceive when your world has been "hanging" on a hook under a wing. Laughing

(Sorry! couldn't resist!)
Those of us who have had the pleasure of loading and unloading weapon bays for the last 30 years are slightly amazed that these delicate munitions can't take the duty cycle of years of wear and tear before being "launched". ? I looked at a F-35B weapons bay diagram and noticed that the "cool end" of the jet was beside and behind the w. b. Granted that sitting on the ground and operating "on the deck" can create higher temp environments but is there no designed airflow into the weapons bay for vapor dispersion/ cooling? That said, all our gravity devices and missles have not led a sheltered life hanging out, under the wings during patrols. So I'm stumbling here, some one help me understand how the F-35/ -22 is uniquely creating an unseemly environment for our weapons, to the end "..a new one... heat and vibration in the weapons bays" Is this real or "much ado about nothing!"?

I'm confused, for AW Amy has posted some good aviation articles and technical opinions don't always agree but "I ain't getting this'un! Crazy Pilot

Something about the F-35 family is of concern to some one some where some time. My fondest memory of an otherwise amazing weather event - to look at - had a deleterious effect on our captive AIM-9Bs. Being wingman to BossMan we flew near but not in nor too close to a water spout and a rolling low level frontal cloud in the forefront of a violent southerly change advancing up the South Coast of NSW near NAS Nowra. Upon landing we discovered the glass heads of the Sidewinders shattered. WTF? Must have been a sudden temperature change; unless we happened to fly through some microscopic hail (that we did not see nor experience). I'll gather that SideWinderGlass is way more robust these days. Very Happy

Neptune - An explanation is that safire is tougher than e-cards. That thing on the wing pretty much stays there munged on the pads because of cant and aerobody lift. Shake amplitude over time is damped as a consequence. Dated ordnance contained fewer things to go wrong. The internal beams on F-22/F-35 are transmitting the engine movements almost directly to the modern ordnance, said ordnance containing more to fail. Naturally there are concerns regarding weap electronics, I rather doubt temperature variance is at play. 0.02

I was also puzzled as to how any weapons bay could be more stressful than hanging at half-face left/right on a Superhornet pylon, but here's the thread with article link on the subject... my own smartass comments already included. http://f-16.net/f-16_forum_viewtopic-t- ... r-asc.html

All valid points...the one thing i would say is that those guys aren't fragged to tackle IADS with su-27s shootin at you, nor do their airframes routinely pull 9 Gs. Is there a difference between a UH-1 and an F-16 vis-a-vi airframe lifespan? maybe the f-16 engineers can answer that one. But yes, SLEP would be awesome, but i have a sinking suspicion it won't make it to the books as it bows to the pressure of the f-35/budget

If IADS or Su-27s get you, Pedro will most likely brave that stuff too just to pull you out. If not, they can always get Army Hawk pilots! Remember, when a helicopter flies it's pretty much hanging from it's rotor system. If you sum the forces and duration it is probably a lot. I'm not sure if there is parity with a fixed wing fighter, but the force/stress is still enough to cause airframe cracks and require more inspections as the bird ages. Engineers have been VERY good at finding ways to fixed and upgrade heavily used airframes. Once the current Army fleet of choppers are retired they'll probably have 40+ years on them. Pilots, even still, are flying the same Chinooks their dads flew in Vietnam, as an example. CH-47A to CH-47F is quite an evolution.

So I see there is a lot of dialogue here discussing the 'facts' of the situation - but I am a woman of action. How about let's see some wanna-be F35 engineers put their hat in the ring for the Flight Test Program at Edwards AFB, CA or Patuxent River, MD? There are a few planes expected to be coming into EAFB needing a brand new flight test team.
To make it easier, here is the link for the 60+ positions between those two spots: http://www.lockheedmartinjobs.com/progr ... httest.asp
If you need someone to review your resume before you submit for a job, I can help there too.
And to make it easier there are relocation packages.
Long live the F35!
Cheers!

AND here is the chat forum: http://www.lockheedmartinjobs.com/chat.asp
This week there are three conversations leading up to the SFTE Symposium at Fort Walton Beach, FL Oct. 1-4. Lockheed will have a booth there with unconventional incentives for you to come visit!

If only I had graduated already. I'd be all over that! I'll put my hat in the ring once I graduate.

You got that right brother. Nearly all serious funds available for manned TACAIR upgrades are being sunk into the F-35. Furthermore, the budget environment is only going to get tougher come January.

Is Aero or Orlando offering these positions to the folks on the layoff list, Leslie? There is plenty of talent already at LM to do these jobs.

I'll settle for a flying or support position with some ANG wing in a while- eight years at the least.

I enjoy living and working in downtown Chicago too much. I have also lived in southern California and visited Maryland enough times to know those states are not for me. I further doubt the jobs listed pay north of X and my household has grown accustomed to my income. Happy to assist if you need outside patent counsel though.
