DERIVATION OF WEB THICKNESS EQUATION FOR TELESCOPING
TUBE DEVICES
Where:
P = internal pressure
A = equivalent average area of inner and telescoping tubes
m = mass to be propelled
Where:
Where:
r = linear burning rate
B = constant of proportionality in burning rate equation
Where:
tb = time at "all burnt"
Refer to figure 44 for the acceleration-time curve from which the following is deduced:
