EFFECT OF THE CLEARANCE BETWEEN ROWS OF COAXIAL PROPFAN ON THRUST
The thrust of a turboprop engine depends on many factors, one of which is hydraulic loss when flowing around the propeller blades. When using coaxial propellers, this factor plays an even greater role, since in this case the losses associated with the ...
