Yawsonde Tests for Prototypes of the 155mm Intermediate Volatility Agent Projectile
Abstract
Twelve yawsonde-instrumented, intermediate volatility agent (IVA) projectiles were tested at the BRL Transonic Range facility during August 1980. Two payload designs were tested. These 155mm prototype binary shell utilize a set of tandem, axially aligned canisters. The canisters are of different internal diameters, however. After rupture of the burst discs that separate the canisters, the interior geometry is not a simple cylinder as in the case of the 155mm M687 or the 8-inch XM736 binary projectiles. This unusual interior geometry cannot be easily analyzed for destabilizing effects of the liquid. Data from Charge 4 and 6 launches indicated stable flights for both canister designs. Previous tests at Dugway Proving Ground (DPG) had shown that one of the designs was unstable at Charge 4, but yawsondes were not employed so little information is available as to the nature of the unstable (or stable) flights. Since a reliable mathematical model is not available to aid in the design of the canister IVA configurations, additional testing must be conducted.
