Figure 9.

The average aerodynamic performance of a hummingbird wing and micro helicopter rotor (ProxDynamics Black Hornet) is equivalent. (Low intensity curves are species-averages for hummingbirds shown in c,f,i.) Lift coefficient (a) and lift–drag polar comparison (b) show hummingbirds generate more lift at high angles of attack. (c) The power factor of the average hummingbird wing is equivalent to the helicopter rotor at downstroke and upstroke angles of attack relevant for hummingbirds, and rotor angles of attack relevant for helicopters. (Online version in colour.)

Hummingbird wing efficacy depends on aspect ratio and compares with helicopter rotors
