Aerospace / Defense
Over the course of the Iraq and Afghanistan wars, many soldiers have lost their lives in Humvee rollovers, when doors were jammed and they were trapped inside. The Department of Defense requested ideas from contractors to address the problem. One manufacturer proposed a solution: A prototype windshield with two quick-release latches that would allow soldiers to push out the windshield and escape in under five seconds.
Our engineers identified specific requirements they would have to address:
PGC engineers developed same-day prototypes onsite at the manufacturer’s facility until both primary and secondary seals were functionally modeled and installed on a windshield. The unit was mounted in a shaker table to simulate conditions in the field. After a 24-hour trial, it passed all vibration, install and removal tests. PGC then proceeded with the next step: developing and manufacturing eight production-level sets of windshield seals, ready for overnight shipping in one week. The seals were delivered on time, with performance results exceeding expectations. After further refining profiles, working drawings and materials specifications, PGC moved into full production.
From proofs to prototypes and concept to full production, PGC used a robust set of processes and multiple supply chain resources to meet stringent specifications and timelines. Our customer’s designed it to be installed by Army or Marine maintenance personnel in approximately one hour, the windshield kits have been used on the 1151 Series Hummer and newer MRAP Vehicle designs across multiple vehicle platforms.
