KTPPA results
The KTPPA chart helped us in the
situation where the Crossbow wouldn’t launch.
We checked the design and out predictions and realized that it wasn’t
the basket or design but the actually the type of bungee we were using. We found this out through testing. This follows our predictions on our KTPPA
chart. We corrected this problem and
hopefully we won’t have to use any of our contingency plans.
