Impulse theory and small-scale blades
Posted May 26, 2015 at 07:37 by skeptik
Very simple, very reliable impulse theory applied to small scale rotors, quad's alike, seems to be very promising.
Espesially at low velocities.
The data about propeller were obtained in thesis Isa Diana de Sousa Baptista Morais Carvalho "Low Reynolds Propellers for Increased Quadcopters Endurance",
the experimental data scrached from http://m-selig.ae.illinois.edu/props/propDB.html
Sure, it can be more precise but i've only used classical work of Yuryev.
(Boris Yuryev (1889-1957), a Russian/Soviet scientist in the field of aerodynamics and academician. Inventor of swashplate for helicopter, which allow to control of helicopter flight)
Anyway it can be upgraded for the time.
