I reaaly appreatiate all your imputs
I am in no way trying to build anything, it just got my attention looking at a SuperPuma FM (AS332L2) that is limited for land/take off to 7000 ft DA ... for such a "powerfull" heli does not seem much altitud for a landing or take off...
That is way I wanted to know what differences are there is design that gives extra values when it gets hot&high.
Of course if you what to land above 20.000 ft you don`t take twins ... but that is not my curiosity. What I would like to learn is if such type of rotor performs better that others, type of compressors, blade design...and such.
I understand that is quite technical but I am sure there are some of us around that know somethings about all this.
Thanks to all of you in advance
