A Transport and Diffusion Model for Smoke Munitions

摘要

The US Army Materiel System Analysis Activity (AMSAA) smoke model was developed to provide smoke effectiveness data for the tactical planner. Its purpose is to predict the size, duration, and effectiveness of an obscuring screen in a battlefield situation. Either burning pyrotechnics or explosive munitions may be handled. Starting with the weapon's or battery aimpoints, the screening cloud is developed, diffused, and transported in accordance with environmental conditions. Aiming and precision errors developed in the firings create impact 'displacements' which can produce 'holes' in the smoke screen. The screen is continuously examined to evaluate its effectiveness as determined by the obscuration along various lines of sight originating from an observer's position. The model is adaptable to a wide spectral range and various visual aids depending on the input data employed. (Author)
