Abstract: This paper describes the development and verification of a basic targeting model for gas pressure launched explosive projectiles used for avalanche mitigation. The model uses the basic physics of flight including aerodynamic drag and the effects of gravity. The avalauncher round is unique, compared to artillery rounds, in that its drag coefficient changes during flight. This uniqueness is handled in a manner that relies on currently characterized avalauncher shot settings to establish the aerodynamic drag coefficients (Cd) empirically. The model has been used with good results to modify existing shot placement data, and also to develop new shot parameters. This model will reduce costs and significantly improve safety over trial and error techniques.
