Introduction

  • Thee ffective power of air propeller

  • Definition: a propeller produce pull, pull a plane to go forward, to do work for aircraft. Propeller per unit time, work is the effective power for the propeller. Formula: N oar = PV type: N oar - the effective power of the propeller;P - propeller pulling force; V - speed

  • The propeller effective power along with the change of the speed: (1) the ground test run, the plane did not advance speed (V = 0), tensile, work is noton the plane it is "zero" the effective power of the propeller. (2)the speed increase, from the actual measured curve of effective power propeller: in OA speed range, the effective power of the propeller as the speed increases; After the speed is greater than the scope of effective power propeller decreases with increasing of the speed. Within the scope of the OA speed, when the speed increases, the tension decreased slower, along with the increase of speed, propeller effective power gradually increased. When the speed increases to A propeller of effective power is the largest. When the speed increase again, due to pull rapidly decreases, and thus increased with the increase of the speed propeller effective power will reduce. Is engine drives the rotating propeller, the propeller is the engine's power to pull forward the effective power of the plane. Effective power propeller and the ratio of the engine power output, called the propeller efficiency. Eta = Noar/N effectively
