What kind of airframe materials will they need for 9Gs? That sounds like too much for even aerospace Titanium.

- throwup238 2y agoF22 rated load is 9g continuous (~13g burst) and it's made with mostly Ti64, thermoset composites, and aluminum [1]. It's much lower than it can be because there's no point in investing in a stronger airframe when the sustained acceleration would kill any pilot. These unmanned drones can easily be designed to withstand much more.

- alluro2 2y ago9G shouldn't be a problem at all, from a material standpoint. Missiles go to 100G, and F1 engine pistons withstand 8.600G (https://en.m.wikipedia.org/wiki/G-force https://en.m.wikipedia.org/wiki/G-force).
- mkl 2y agoTo clarify, that's 8600g, not 8.6g. Also in that table: Acceleration of a nematocyst: the fastest recorded acceleration from any biological entity. 5,410,000 g!
- fennecbutt 2y agoAh the list sorts alphabetically and not numerically, looks like.
- ahazred8ta 2y agoThe F-16 avionics are limited to 9G, but the fuselage is able to handle much more when not carrying a full load of fuel. 9Gs is standard for a fighter.
- luma 2y agoThe major failure point in a 9G-capable airframe is the meatbag that is traditionally placed inside.
