A video of a metallic orb captured by a US drone has sparked curiosity about its flight mechanics. The prevailing theory suggests that helium may provide lift while wind could serve as propulsion. Some participants liken the orb to a mylar balloon, raising questions about its true nature. However, the discussion is focused on the potential technology behind the object's movement rather than debunking UFO sightings. The thread has been closed to maintain this focus.

TL;DR
A US military drone caught a fast moving metallic orb in the middle east with no visible rotors or exhaust. Its trajectory was straight so it wasn't shot like a cannon ball. What could be its propulsion method?
Here is a video of the metallic orb captured by a US drone. Wondering about the physics of how such an object could fly.

The most likely technology is helium for lift and wind for propulsion. "Metallic orb" sounds a lot like "mylar balloon". But we don't do UFO debunking here so this thread is closed.

Thread 'General principle of turbomachinery: true also for rocket turbopumps?'

A rule of thumb of aircraft engineers is every 10% increase in the power level engines are run at corresponds to a 50% decrease in engine lifetime. This is a general phenomenon of turbomachinery. Then it is likely it also holds for rocket turbopumps. Then quite key is the rule also holds in reverse, every decrease in power level by 10% can result in doubling the lifetime of the engine. Then by running the engine at 0.9^5 = 0.60 power level can result in 2^5 = 32 times longer lifetime. For...
