Calculation rule "Emilio Herrera. Calculation rule on continuous cylinder and rule of proportion and equivalence. The printed letter attached to the cylinder has yield curves of: speed in km/h (50-800), power with propeller yield - at two scales 1000m - 6000m/7000m - 14000m, sea level weight, performance coefficient 0 , 5 - 1. The calculator has an equivalence rectilinear rule in square meters = horses = kilograms, with scales 10, 100, 200-1000, 2000 - 8000. It consists of a mobile tubular rule, which also serves as adjustment with the tubular. It presents logarithmic yield curves, at the surf
