Drone Flying Autonomy Calculator

This program allows to calculate the maximum flying autonomy of a drone.

Fill the following form with your own data =>

Propellers diameter		meter
Propellers number		2 coaxial propellers account for 1 propeller. Sorry...
Battery specific energy		W.h / kg
Battery weight		kg
Total flying weight of the drone		kg
Propeller efficiency		%
Engine efficiency		%
Battery efficiency		%
Air density		kg/m3 1.225kg/m3 (15°c, 1013.25hPa), 67kg/m3 on Venus

RESULTS

Maximum stationary flight duration =

Please note : this modelisation is a first approach for information purpose.

IMPORTANT : the autonomy is proportional to the propellers diameters.

formula :
(mass flow): dm = 1/2 * rho * Surface * V
(power flow): Power = 1/2 * dm * V²
Traction = dm * V
...
(absorbed power) Pa = 1/4 * rho * Surface * (2 * Traction / (rho * Surface))^(3/2)
