Absorbed power :
Usefull power :
Peripheral Mach :
Mach => do not exceed 0,65 Mach or the propeller would be too noisy
This simplified modelization allows a first approach for information purposes. It does not take into account the mechanical aspects imposing on blades a certain geometry. It calculates the propeller's efficiency at a specified point of functioning.
This modelization is precise @ + / - 5%.
E-PROPS engineers realize more pushed calculations and more detailed analysis to define the aerodynamic geometry and the mechanical behavior of the blade under load, as well as the precise performances in the various points of functioning. The LmPTR© software has been finalized in this purpose. Every E-PROPS propeller is realized for a specific configuration and engine, and naturally according to the pilot's specifications.
