Abstract: This paper proposes a novel stator-permanent-magnet axial-flux counter-rotating hybrid-excitation machine (SPM-AFCRHEM) for unbalanced-load operation of counter-rotating propeller (CRP) ...
Abstract: The counter-rotating axial-flux hybrid-excitation permanent magnet (PM) machine is a novel power device specifically designed for counter-rotating propeller (CRP) systems. Cogging torque (CT ...
The Gordon Murray T.50 has the highest specific output of any street car, generating a whopping 165 horsepower per liter of engine displacement. This is what we motorcyclists would call utterly boring ...
The An-70 transport is a high-wing military transport powered by four 14,000-shp ZMKB Progress D-27 “propfan” engines with six-blade counter-rotating propellers. Maximum payload is 103,615 lb. Two ...
