    Calculating Load for a Mini Wind Tunnel?

    I know a big circle but well worth your thoughts and input...thanks

    Calculating Load for a Mini Wind Tunnel?

    It was just clarified that the hp was a lot less(1-5hp) but that the torque and rpm are still consistent (I honestly don't know why HP=torque x RPM /5252 must not apply here or something) and the CFM at max free spin Load is 6CFM @90psi my carbon fiber air tanks are just enough to supply this...

    Calculating Load for a Mini Wind Tunnel?

    Yup I just checked the math u r right but I was referencing free spin and trying to factor in the load I only need 150hp(figurative) or 125ftlbs torque and 6000rpm if the 1hp air motor can deliver this at a good CFM rate il use it...I'm guessing the planetary gear reduction won't kill to much of...

    Calculating Load for a Mini Wind Tunnel?

    Yeah I'm sure it takes a ton of air...and it does so with a planetary gear system...
  5. Q

    Calculating Load for a Mini Wind Tunnel?

    HP=torque x RPM \ 5252 The math says so 750ftlbs torque x 9500rpm /5252= 1,300hp factor In load so about 1000hp so I'm not really sure... It is pretty strong so I'm not doubting it plus the energy is stored in compressed air tanks so a large engine is not required

    Calculating Load for a Mini Wind Tunnel?

    Yup I'm planing on using titanium shafts
  7. Q

    Calculating Load for a Mini Wind Tunnel?

    Smart guy but I'm using a air powered wrench not electric a little different the electric has peak torque to save energy but the IPM (impacts per minute) are different from RPM so it's true the peak torque but that is continuous because it's separate from IPM in true air powered wrenches

    Calculating Load for a Mini Wind Tunnel?

    Hey guys, so I'm building a mini wind tunnel and I would like to calculate the new RPM,HP and Torque since the propeller will act as a load and change the specs of the motor(note I'm using a air wrench as the motor as it's all I had around and have disabled the impact motion) the current specs...
