hey there
do you have any idea how i could estimate masses (most important to me at the moment are rotor, gerabox, fuselage) for a VTOL UAV in standard configuration with a MTOW of about 180 kg?
so far i tried several empirical formulae but all result in unusable date (negative values etc) because they are derived from much heavier vehicles.
by the way: does anybody know where i could get the boeingvertol formula fur helicopters? unfortunately they're not in my books... (it's only mentioned that tehy exist...)
thanks for any hint...
ps: and i can't just by an vtol heli and measure everything...
