Overhead Threat Protection (OTP)

In expeditionary environments, shelters such as the Tent Expandable Modular PERsonnel (TEMPER) tent continue to be the primary means of housing command, communications and administrative functions and for the hotel accommodation of our soldiers. In this same environment the increased occurrence of mortar and rocket attacks has significantly raised the threat to our troops from blast and fragmentation. Although sandbags, concrete barriers, and other defense walls have traditionally provided added ballistic protection for our troops, overhead protection from indirect fire for these soft shelters has always been lacking. The army is now pursuing is a method to provide this additional overhead protection plus offer the stand-off initiation of RPGs in a configuration applicable to soft shelters. At the completion of the Phase II effort, TPI will have demonstrated an Overheard Threat Protection (OTP) frame structural system that meets all the U.S. Army requirements to provide force protection to a wide range of soft walled shelter systems. We will have completed Finite Element Analysis (FEA) and provided analysis of the overpressure impulse loading and static loading of the OTP system. In addition, we will have fabricated multiple full scale and complete OTP systems for user trials and live fire blast testing.
