Did you miss that the analogy would have “rotor input” instead of a replacement rotor, and that I agreed it would require some domain knowledge, or is this just you adding toxic snark to look clever and discourage substantive contributions to these threads?
In any case, the record player analogy is still unhelpful because it conveys no practical intuition about why a record might break its player — that doesn’t happen in practice. Unless you want to make a substantive remark by showing an everyday case where a normal record might come close to breaking a normal player.
- viscanti 4y agoGiving someone a rotor input seems unrealistic. I've never heard of someone gifting one and who would swap out a rotor input with one that would cause damage to the helicopter? I think readers would find that example too farfetched.
- SilasX 4y agoFirst of all, I already agreed in the initial post that it would require some experience with helicopters. Second, in this case, "giving it a new input" could be as simple as "changing the standing rotor speed -- 5500 RPM instead of 6500 RPM". They're so finicky, you don't need to specify a complex time history to hit a dangerous resonant mode-- though it certainly helps! Third, the fact that it's a gift is not at all required for an analogy. Of course you don't have to keep that part, and would have to reframe it so that the details of how the helicopter is provided a new input are different. You're not even trying to be charitable at this point, but make it sound as stupid as you possibly can. Please work on your curiosity.
