Summary

Gas dynamic loadings experienced by a projectile passing through the muzzle gas flow field are investigated by inducing deliberate asymmetries in the muzzle flow. The effect of these asymmetries on projectile yawing motion near first maximum yaw is measured in a ballistics range. The measured data is extrapolated back to the muzzle, and the projectile angular velocity upon penetration of the muzzle blast is evaluated. The projectile linear velocity imparted by the asymmetric gas dynamic loadings is estimated using the hypersonic equivalence principle. The total jump of the projectile trajectory due to both angular and linear velocity is computed and compared with measured values. (Author).
