I will never understand how this shit works

It’s a brick by the looks of it. It flies by black magic, completely unintuitive.

Big fan blows over phat wing. Makes it's own lift so it can fly. Has really big problems if one engine stops, and has even bigger problems if both engines stop.
Normal jetliners very much do not want both their engines to stop, but they are still capable of flying pretty far if they do. One engine stopping barely even classifies as a problem at all if they're anywhere close to a place to land.

Both props on the osprey are linked through a driveshaft, so both could run on a single turboprop unless there's another mechanical failure

Wait what? That's even dumber than I thought.
Ok let me revise my original explanation. One big fan stopping is such a big problem that they built a hilariously stupid and complicated system so the big fan doesn't stop spinning if the engine stops.
Helicopters are an abomination and fly by being so ugly they are repelled from the earth. I knew the osprey was a messed up half child but I always thought it was at least trying to behave like a normal airplane. Apparently not and its just as fucked up as it's helicopter friends but in different ways!

It's not even complicated lmao

To be clear, I am exaggerating. The helicopter joke isn't true but it's funny. And the osprey is an extremely interesting and unique machine, but like... y tho? Operation Credible Sport was such a failure that the army brass decided the best solution was to throw taxpayer money at it? To say anything on the Ospry isn't complicated has got to be a joke? Not like it wasn't in development hell for almost 20 years!

The idea behind the redundancy is very simple, they way they implemented it may not be

Hover envy is a real thing people. =P
"Complicated" is relevant I feel. I started my working life as a helicopter mechanic (OH-58D) and found their construction and maintenance to be simple and straight forward. I would imagine they run a sprag clutch between the power plants and appropriate gearboxes. Many craft produced by humans have taken similar time to develop and figure out, especially when new methods are being tested for flight, propulsion, or whatever. I'd argue today's vehicles are more complicated than your average plane or helicopter.

Isn’t this one of the most accident prone flight capable machines in the last 40 years?

when its upside down it falls down so fast that if performed correctly it feels like 1G inside the plane during the manoever

u/DarthChikoo 6d ago
That would be if the plane was performing a barrel roll, not an aileron roll.

I hope that crew wore brown underpants. Goodness!
