Simulation and Analysis of Dart Dispense Events with Collisions
Abstract
Current approaches to beach and surf zone mine clearance depend on the dispensing of large numbers of darts from a parent missile or projectile. The mine clearance mission requires a uniform distribution of darts over the target area. The dispersal pattern is affected by many factors, including the angle of attack, velocity, and rotational rate of the parent vehicle, the aerodynamic design of the darts, dart collision, and the different aerodynamic regimes that exist in the vicinity of the dispenser. In the overall effort, computational modeling and simulation is used to provide insight and understanding of the dispense event. The primary long-term goal of the present effort is to understand and characterize, through simulation, analysis, and comparisons to wind tunnel and flight tests, the most important physical processes underlying the behavior of dispense events.
