To meet the requirements of an aluminized explosive cylinder test with a longer energy release time, a non-standard cylinder structure with a larger wall thickness was designed, which can not only extend the effective expansion time of detonation products but also avoid a great increase in the test charge mass. The non-standard cylinder was filled with TNT explosives for its relatively stable Gurney energy, and the experimentally generated parameters were compared with those of Φ 50 and Φ 100 mm standard cylinders. Based on this, a more accurate Gurney Model for Non-Standard Cylinder (GM-NSC) was proposed taking into account the influence of shell deformation and axial movement of detonation products compared with the traditional Gurney model. The analysis results show that the proposed GM-NSC model curve is suitable for both non-standard and standard cylinders. Finally, the method was applied to DNAN-based aluminized explosives, and the experimental results show that the method can characterize more thoroughly the effect of the detonation product expansion enhanced by the rapid reaction of aluminum powders.
