How much "Thrust" could WWII aircraft such as the P-51 P-47 generate?

    Greetings,
    I've always wondered if there has been any research or conversions showing the amount of "thrust" some of these old warbirds could produce? After the engine dumped it's power in the prop and the prop transfered it to the air, how much was the reaction force (in lbs) which propelled the aircraft forward?

    I thought it would be interesting to compare it to those figures of the turbo-jets.

    Thanks,
    CS

    An Aero Propeller is surprisingly efficient. Under ideal conditions, it can convert about 70-80% of the power supplied into thrust. If I were just trying to estimate, I would use a low forward speed such as 15-20 mph and 70% efficiency to do the calculations and see what results. The formula for static thrust is different if there is no forward motion.

    Here is a primer on jet engines from the 40's which touches on this subject
