Akerman, 1940 Boeing Report No. The angle of the air approaching a blade is a combination of the airplane's forward speed and the propeller's rotational speed. The aircraft propeller is essentially a series of rotating wings or airfoils of equal length, which meets at a common central hub . By FRED E. WEICK and DONALD H. WOOI) . Wing design is constantly evolving. Reverse-Pitch Propellers. Right page scan # 9. Most of these engines were air cooled by air flowing back through the propeller and over the cylinder heads (the tops of the cylinders sticking out from the engine).
