Calculating Propeller Thrust Using Given Data

[mohd_omr]

i need to calculate thrust produced by a propeller whilst flying, using the data show below. all equations i have come across require the propeller induced velocity which is not given.

things i know;
-propeller efficiency
-indicated and true airspeed of aircraft
-temp. and pressure at flying altitude
-engine torque
-propeller diameter
-propeller rotating speed

i have tried serching the forum but couldn't find a relevant equation.

propeller efficiency and thrust are functions of airspeed.

Dear buddy,

It takes some iteration to calculate thrust distribution for propeller. However, I can help u to do that coz during my final year project, I've assigned to design and find performance of the propeller itself.

U can give anything that u know abt the propeller, and I will try to help u on that. Email me at solehan85@gmail.com

For your given situation you can use the following relationships to solve for thrust.
