Static Thrust Measurement for Propeller-driven Light Aircraft

Since in-flight thrust is a calculation based upon a number of separate measurements.Only on the ground, either in an engine cell or during a static thrust run, do we actually measure thrust using load cells.In this thesis a device was devised to measure the static thrust of propeller-driven light aircraft.Also a static thrust model of propeller-driven light aircraft was established to compare with test results.Three propeller-driven light aircrafts were tested with different diameters of propeller.The propellers of all three aircrafts were connected to engine shaft directly without gear box between the propeller and engine shaft so that propeller revolution speed was regarded to equal to engine revolution speed (RPM).
