very nice how do you exactly calculate the total impulse, peak trust, avg thrust ?

@elibaba7 I capture with my camera the test, frame per frame I report the thrust on Excel, say that I have 30 values, for a 1,2 sec burn.
Excel calcul the average thrust, say 15 Kg
The peak thrust is the maximum thrust, say 18,5 Kg
The total impulse is the time in seconds multiplied by the average thrust, => 1,2*15
Hope you understand ( sorry for my english )
