I wonder how they became mobility impaired? Home made mobility scooter trailer. Surely not a registered trailer either. https://twitter.com/MacsinSpace/status/1110055952516931585

It is, but the delta there is only the pressure of that two feet or so of water, which is like 1 psi.

Because that's how many pounds are pushing you into it. Now imagine being stuck in it with your head under water.

The real squeeky bum with helicopters as I understand it is when you see one flying below about two hundred feet. Because that's the envelope in which they cannot auto rotate in the event of engine failure.

Grem posted:Flown in helicopters plenty in the Marines. Their natural state is crashing. Do not tempt God by riding in helicopters. I do a dumb lil drone podcast with some friends every week and once we had an actual helicopter pilot from the Canadian Armed Forces on to talk about flying real poo poo. We all fly racing drones which have like a 10:1 thrust:weight ratio so you can shoot yourself 10 storeys in the air in ~2 seconds He took a guess.... the aircraft he flies might have 2:1. Maybe. I assumed it'd be like 100:1, a real hugeass gas engine running those massive blades. But the giant blades also have inertia that needs to be managed and that affects how quickly you can spool the engine, it was a big eye opener.

Saturn V had a thrust-to-weight ratio of 1.2 at liftoff.

Full-size helicopters are at the point where increasing engine power significantly requires you to make the engine that much heavier. And it's not like extra engine performance lets you go that much faster, it just lets you carry more. So they pick the engine to be as light as possible while still having the desired performance characteristics.

The R-44 is a loving marvel. Especially the part where the exhaust fumes can get sucked into the cockpit heated air system.

SelenicMartian posted:The R-44 is a loving marvel. Especially the part where the exhaust fumes can get sucked into the cockpit heated air system. I’d imagine it has exhaust manifold shroud heating the cabin air like most small aircraft piston engines do. Those systems are basically designed to detect the inevitable exhaust leaks via poisoning/asphyxiation of the occupants. Somehow, fuel heaters manage to combine inevitable occupant poisoning/asphyxiation with the added probability of an avgas-accelerated cabin fire!

So the helicopters were controlled independently? What the gently caress, that would have been a disaster even if the helicopters didn't fall off

There were five people there. The most impressive feat is that it survived two months between the first flight and the crash.

I flew in Hueys, Blackhawks, and Chinooks all the time when I was in the Army. I loved it, especially parachuting from them. It was easier to borrow helos and pilots from the 18th Aviation Brigade because they were always desperate for loggable flight time while our Divisional Aviation always seemed to have its head up its rear end and scheduling light drop aircraft from the USAF was basically an impossibility. "You only have less than half a stick of jumpers? Talk to us when you can fill a Herc..." Us and TACP and CCT always ended up sharing birds.
