It's not that simple, while stainless nearly 3 times as heavy as AL, it's also has about 3 times the yield strength. It still probably would end up heavier but not by all that much, the choice is puzzling because stainless is a pain in the rear end to work with as far as i know, it's hard and rather brittle. (Note that i am not an engineer so feel free to correct me if i'm wrong)

Captain Postal posted:

Steel, Al, Mg all have different tensile strengths. In terms of weight/unit load supported, a steel beam is much lighter than Al or Mg of equivalent strength in pure tension, Al is much lighter in pure compression and Mg is much lighter in pure bending. Other materials are better when the applied load vector is in an intermediate direction.

So look at that structure and figure out which elements are in tension/compression/bending and since all members are under a mix of loadings, how much of each load is being applied. And then choose a material. Then look at how the proportion of each load type varies under dynamic loading like vibration and gusting, and how each bolt/rivet is applying a shear load onto its supporting member, and then choose the best material again. And then redo it all once more as the structure expands and contracts at different rates under thermal loading to introduce internal tension/compression.

It's a really loving complex problem, and when you put it all together you just might find steel is the lightest material to use. And that's before looking at other properties like ease of manufacture and corrosion resistance.

I stand corrected, I hadn't even given thought to the material affecting the design.

Thanks for the link that's better than I could find. I know the club owner and the lead pilot, and have hangared an aircraft whilst visiting earlier in the year. Hopefully he's ok. But it's sad for all involved whomever it is.

I've no idea how Kermit Weeks keeps track of his projects, it must be about a full time job in itself.

Depends on who you ask. The official story was that their new-fangled G-suit (Combat Edge garment) was putting too much pressure on the pilots' torsos due to a problem with the BRAG valve. This exacerbated/was exacerbated by the fact that the Raptor is insanely high performing, which means that you are able to pull higher g loads at a much higher altitude than previous fighters. Combine that with the fact that aerospace physiology had atrophied quite a bit in the USAF and thus you get this.

Others would disagree with the assessment that the Combat Edge is the sole cause. I'd tend to agree with the skeptics. The whole "Combat Edge" thing is a half-assed bandaid on the issue, nothing more.

So this is pretty :stare:

tl;dr - Rivet Joint at Offutt has the entire back end catch fire on the take-off roll, crew starts screaming about fire, pilot thinks someone burnt up a hot pocket in the microwave but goes ahead and aborts the takeoff, crew safely evacs the aircraft. Here's pictures of the aftermath:











Yeah no, gently caress that. If that had happened in the air everyone on board would be dead and the plane would be a smoking hole in the ground. The best part: root cause was found to be shoddy depot maintenance by L-3 on the high-pressure oxygen system, primarily involving hand-tightening fittings that were supposed to be torqued. The leaky fitting in question melted once the fire ignited, which allowed even more oxygen to escape which contributed to the severity of the fire. Since the faulty fitting melted in the fire can't definitively say that the fitting was torqued incorrectly....but given that multiple fittings on the aircraft were found to be hand tight instead of torqued, it seems like a logical conclusion to draw. No word on what they found when they presumably did a OTI on the rest of the fleet.

It was complete dumb luck that the leak decided to ignite at that point instead of any other point in the sortie or any other sortie for that matter.

Damage was estimated at $62M, it was patched up and is at L-3's facility in Greenville getting depot repaired now (presumably not by the same bunch of idiots who don't know how to use a torque wrench, wait who am I kidding it's a military contractor so it's totally the same bunch of idiots.)

I'm kind of surprised it's repairable. Rugged 707 design makes it relatively reasonable or the fact that it's completely irreplaceable?

Wiring and patching the hole. Had the fire consumed the pressure plate at the rear of the fuselage, that could put it in write off territory.

There's not much in that area that's of huge importance equipment wise.

Irreplaceable. At its age, that airframe is a write off in any normal circumstance where replacement is an option. The $62M repair bill quoted upthread is more than a third the purchase price of a brand new equivalent airframe, but the USAF can't build new ones because any new airframe program they start costs a trillion dollars.

(I know that it would cost a lot more than a regular airliner to replace a JSTARS, but it also shouldn't cost multiple hundreds of millions of dollars just to fit the mission suite in a new airframe.)

DO YOU HEAR THAT? THAT'S THE SOUND OF ME PATTING MYSELF ON THE BACK.


Last night, I watched an Air Disasters episode on FedEx Flight 705 wherein an employee attempted to take control of the airplane and the Pilot and Co-pilot (each at different times) pushed the DC-10 WAAAY past it's limits to try to turn the fight to their favor.

quote:

Tucker pulled the plane into a sudden 15 degree climb, throwing Sanders, Peterson and Calloway out of the cockpit and into the galley. To try to throw Calloway off balance, Tucker then turned the plane into a left roll, almost on its side. This rolled the combatants along the smoke curtain onto the left side of the galley. Eventually, Tucker had rolled the plane onto its back at 140 degrees, while attempting to maintain a visual reference of the environment around him through the windows. Peterson, Sanders and Calloway were then pinned to the ceiling of the plane. Calloway managed to reach his hammer hand free and hit Sanders in the head again. Just then, Tucker put the plane into a steep dive. This pushed the combatants back to the seat curtain, but the wings and elevators started to flutter. At this point Tucker could hear the wind rushing against the cockpit windows. At 530 mph, the elevators on the plane became unresponsive due to the disrupted airflow. Tucker realized this was because the throttles were at full power. Releasing his only usable hand to pull back the throttles to idle, he managed to pull the plane out of the dive while it slowed down.

They managed to get the plane on the ground without any serious damage (though I guess some of the skin on the elevators started rippling from the airspeed). All of the flight crew suffered multiple blows to the head with hammers, so they all had fractured skulls and high amounts of blood loss. Guy who tried to gain control of the plane got two consecutive life terms.

The plane is still in service to this day. It had about $800,000 worth of damage to it from the maneuvering.
