Results are provided for an experimental study of the reaction to inte
rnal explosive loading of titanium alloy PT-3V welded cylindrical shel
ls filled with air or water. It is established that shell failure deve
lops a strong scale effect in the form of a sharp reduction in explosi
on resistance with an increase in dimensions. Recommendations are made
for weakening the effect of the scale factor and increasing shell exp
losion resistance. Semi-empirical equations are obtained which are rec
ommended for evaluating explosion deformation parameters for the shell
of a cylindrical explosion protection chamber made of titanium alloy.
