Abstract
Hydrodynamic ram, or HRAM, poses significant safety hazards to commercial and military aircraft. HRAM can increase the probability of fire to aircraft via the resulting transient spray after a high speed projectile has entered into a closed fluid filled container. Therefore, understanding the correlation between HRAM cavity dynamics to the resulting transient spray associated with fire initiations within the aircraft dry bay is needed. Re- search has determined a strong relationship between the cavity closure and the resulting transient spray. Additionally, the cavity volumetric inflection point is indicative of cavity closure. This research will investigate the underlying physical mechanisms driving the HRAM cavity closure utilizing a systematic energy balance approach. Ultimately utilization of the energy balance provides a foundation for predicting HRAM cavity dynamics and the resulting transient spray.
