|Cable Length Calculator|
Calculation of the length of the flying wires connecting the burner load frame to the base of the envelope is a matter of simple triganometry but it is not completely straighforward.
This calculator is one that I developed in Excel to solve the calculation problems. It has been used on many balloons and appears to be accurate. There are separate workbooks for 3 and 4 point load frames.
The sizes of the burner frame and envelope mouth and mouth angle are input on the inputs page and the results will be displayed.
