Towrope tension??

A typical 235Hp Pawnee generates about 400kg of static thurst, that would also be the maximum tension on the rope that the towplane can generate.
On the other hand can the glider generate a towrop tension high enough to break the tope or the weak link if used.

Instead of calculating and modeling these conditions, why not measuring it very accurately? We wanted to know what the force distribution throughout a winch launch is - a far more complex thing than an aero-tow - and built a slick little recorder. It was housed in a 2l soda bottle attached to the apex of drogue chute and recorded the forces and accelerations of multiple launches. The data was compressed and stored on a micro SD card and was read at the end of the day.
