I had seen/heard/read that the thrust asymmetry was a design feature to help with yaw, and that fewer engines would overpower the design limits of other parts of the airplane, to the extent that everything else would need to be redesigned to handle them (mounts, tail, rudder, etc.)

- palunon 4y agoYou can use thrust asymmetry to help with yaw, yes. But here we're talking about unplanned sudden thrust asymmetry, causing a massive yaw force at a critical phase of flight, takeoff, where you're engines are likely to be near their full power and you're close to/on the ground. If you go from 8 engines to 4, loosing one engine goes from causing 25% thrust loss on the wing to 50%.
- tyingq 4y agoMakes sense, but must be also tied to something else unique about the B-52. There are certainly much larger aircraft with 4 engines.
