Thrust Calculator - VOLTCRAFT 23 87 82 Bedienungsanleitung

15. THRUST CALCULATOR

The thrust calculator can be used to determine an average for the expected standing thrust
of a rotating propeller by entering the required calculation values. In addition to the propel-
ler diameter ("DIAMETER") in inches, the maximum speed achieved on the ground
("RPM"), number of propeller blades ("BLADES") and efficiency coefficient ("CF") of the
propeller must be entered.
Overview of the efficiency coefficients of different propellers:
Propeller manufacturer
Standard propeller
APC propeller
APC-SF
APC W propeller
MenzS propeller
Bambula propeller
Bolly Clubman
Cox propeller
GWS HD
GWS RS (SF)
Smart
Zinger Wood
Since this thrust calculation is estimated, the propeller increase is of subordinated
importance. The propeller increase would only play an important role when
calculating the expected flight speed.
