In most planes, pilots are already able to chose their propeller RPM somewhat independently of torque by varying the pitch of the propeller. However, pilots typically optimize for rate of climb and not noise in order to get out of the low altitude / low airspeed danger zone as quickly as possible.
- sokoloff 6y agoYes. What GP is talking about though is changing the range of speeds available for pilot selection by changing the prop length, airfoil, maybe number of blades, and other design parameters. IOW, the design elements, not so much the operational element. Similar to how the C421 cruises at 1800-1900 prop RPM to give a(n eerily) quieter cabin.
- kohtatsu 6y ago"i.e." is functionally the same as your use of "IOW"; IMHO, FWIW. https://dictionary.cambridge.org/dictionary/english/ie https://dictionary.cambridge.org/dictionary/english/ie IOW made me think "I often wonder", but it didn't fit so I had to look it up: "in other words". I think i.e. is cuter. /digression/nit-pick
