F-35 Ejection Seat Fears Ground Lightweight Pilots

An anonymous reader writes: Writing for Defense News, Lara Seligman and Aaron Mehta report that "[c]oncerns about increased risk of injury to F-35 pilots during low-speed ejections have prompted the US military services to temporarily restrict pilots who weigh less than 136 pounds from flying the aircraft. During August tests of the ejection seat, built by Martin-Baker, testers discovered an increased risk of neck injury when a lightweight pilot is flying at slower speeds. Until the problem is fixed, the services decided to restrict pilots weighing under 136 pounds from operating the plane, Maj. Gen. Jeffrey Harrigian, F-35 integration office director, told Defense News in a Tuesday interview."

      It's a minor design issue discovered during testing. They happen in engineering. The solution is to fix it.

      Not sure why this was a problem and why they couldn't use an existing ejector seat design but perhaps they have to be designed on a per-aircraft basis.

      And because a technologically advanced industrial enemy would easily take down all those drones by simply jamming communications or, more radically, shooting down the communication satellites. Why, IRAN managed to hijack a US drone. Of course they're not camel humpers but they're not Russia, China or India. Why, using drones against Russia would mean eliciting an armed response against the US satellite fleet. And you can bet they're not restricting themselves, either. Fancy living without GPS?

      Agreed, when it comes to the F-35, slashdot gets bombarded with the uninformed and the Anonymous Cowards. Short memory is an unfortunate human trait. As ejecitons from contemporary aircraft have never been problematic or ever killed pilots? Or is it simply that further testing of the Martin-Baker designed seat produced questionable result when constraining lightweight pilots? But I know it's more fun to simply trash talk the F-35 instead of preventing further deaths.

      Because it's so difficult to add a couple of 20lb weights to the seat if there's a lightweight pilot in it.

      (To the seat because you don't actually want to be wearing a weight belt if you have to eject over water.)

      We can put fuckton of small relays in LEO at negligible cost (relative to the F-35 project). Alternatively, if the opponent does have a ground based laser anti-satellite weapon (the only viable way of dealing with the fuckton of satellites) you could use a drone swarm with a mesh network. Either way you can use highly directional communication, which makes jamming moot.

      Jeezuz, man - your scifi scenario has so many holes in it, you probably like hte idea of screendoors on submarines.

      You know what happens when you take out 1 or two LEO sats? You take 'em all out. And you don't even need to hit one, just put up more shrapnel to take em out. If someone was foolish enough to try such a scheme, and a nation was desperate enough, just think of a space hand grenade. Rocket designed to fragment after reaching orbit, and no more "fuckton" of sats. You want ot talk about inexpensive? Every new Sat you take out will become more shrapnel to take out others.

      There's a reason why there have only been a couple tests of antisatellite weapons.

      Our first war in space will be our last war in space. As we filled up desirable orbits with debris, we'd have to wait until it de-orbits to get anything new through.

      Non starter idea. And your buzzword salad of mesh networks and highly directional comms is just that - buzzwords.

      Remember, you don''t design weapons to be only used against people with mid 20th century tactics. You eventually come up against a technologically savvy opponent.

      On the other hand, the ideal fighter pilot isn't actually very big, since cockpits are crowded, and smaller entities can handle g-forces better than large, muscle-bound types.

      Isn't your comment sexist in itself because you're making assumption about the weight of someone based on their gender? It's like assuming a woman is weaker physically than a man just because she is a woman, even if statistically men develop more muscle mass that does not mean a man automatically has more physical strength.

    Iranian chest thumping about this incident is NOT born out by these things called facts. You will also note that the Iranian claim to have reverse engineered this drone has not resulted in a similar Iranian drone.
