Abstract
According to the FAE static blast experiment, the experimental data of three parameters (overpressure, positive pressure time and impulse) were obtained, and the separate fitting formulas were given. Investigation results indicated that the FAE blast field was divided into cloud zone, cloud boundary zone and shock wave zone, the first two were strong damage zones. In the cloud zone,overpressure and impulse fluctuated slowly, and it maintained high overpressure and strong impulse features, and its positive pressure time fluctuated between 1. 18 ms and 1. 27 ms. Beyond the cloud zone, overpressure and impulse presented decay trend, however the trend was more slow in the shock wave zone than in the boundary zone. Positive pressure time presented growth trend in the latter two zones, however the increase was more rapid in the boundary zone than in the shock wave zone.
