Introduction

The function of a propeller on an aircraft is to provide propulsive force. This lab report was aimed at studying and analysing the propeller and some engine properties of a Cessna 310R. The axial momentum theory, advance ratio and the energy method for fuel
Taking the pitch angle as 30o the propulsive efficiency for these three rpms is 0.54, 0.74 and 0.92 with reference to the above Propeller Efficiency-Advance Ratio graph.

Power Coefficient
At 47m/s (take-off speed), the advance ratio at 1000 RPM, 1500 RPM and 2000 RPM is 0.64, 0.86 and 1.4 respectively. Taking the twist angle as 45o the power coefficient for these three rpms is 0.003, and 0.029 for 1000rpm and 1500rpm respectively with reference to the above Propeller Efficiency-Advance Ratio graph.

Fuel flow

The table below shows the measured values of the fuel flow from the cockpit fuel flow indicator.
