tnx for your replies so far!
I looked at the website of zenithair but havent found something helpful yet.
and i already selected a prop diameter (D_prop=1.22m) based on the maximal possible tip velocity, prop rotation , power_required for other flight phases, an estimate for prop efficiency...
no woes for the answer ;) and i am sorry if my question is a bit naive or so.
i know that efficiency depends on the specific propeller used (advanced ratio, power coefficient..). my problem is that i dont know yet which kind of propeller will be used (and so i dont know the propeller...
Hi everybody!
can anybody tell how to estimate the propeller efficiency at take off?
Are there any reference data available?
I am doing an conceptual design of a low speed aircraft and want to use the slipstream velocity as a kind of "extra high lift" device, but there for a need the prop...
