When it comes to aircraft a statement like „less is more” is obvious. If it has a smaller weight it can carry more fuel and more armament. But what with the brave soul sitting inside of the machine?
Well the same goes for the pilot. I mean his gear of course. When you sit in a fighter jet and fly a steady path with low speed extra stuff that you have to carry on your head is not much of a big problem. But when you are pulling a lot of G’s in a tight turn suddenly your head starts to weight a lot and making your life easier would be much appreciated. This means heaving less on your head. Especially when it comes to modern fighters.
Pilots have their new generation helmets which can track their heads, display a ton of information and… cost a lot of money. But there is always the down side. They tend to weight a bit. That is why F-22 pilots don’t like the idea of having a helmet similar to the one in F-35. It would harden their work and as we know these guys know their job and are the elite. If they say that something is not good for their performance they are probably right.
All of this has helmet magic has to be done because of the ejections seat problems. The whole system has to weight less so that in the case of an emergency the possible injury to the pilot is minimal.
That is why the new helmet for the F-35 is being reworked. The previous model weighted around 2,3 kg but the new one is supposed to be just 2,1 kg. Cutting 200 grams out of it is a lot. That is nearly 9%. What does 200 gram mean in a tight turn? Well when you pull 7 or more G it means a lot less to hold with your muscles which makes the fight easier which can benefit to the overall outcome of it. But when you eject there are a lot more G’s you have to live with and especially then the lighter helmet comes in handy. Less is more!
