Abstract
Aircrew safety is paramount in the design of a helmet-mounted display (HMD). For the tactical aircrew, ensuring a successful ejection presents significant design challenges. The Joint Helmet Mounted Cueing System (JHMCS) Integrated Product Team (IPT) has been evaluating Vision Systems International's HMD design for aircrew protection in this environment. The JHMCS IPT has developed a set of test objectives in concert with acquisition reform to demonstrate ejection compatibility of the JHMCS. This testing series will be discussed, and will include windblast, ejection tower, and sled and in-flight ejection testing, findings and design impacts. JHMCS performance parameters evaluated include structural integrity, facial and head protection, neck tensile loads, ejection seat and crew equipment compatibility, and mechanical functionality. The design environment for the JHMCS currently is both small and large, male and female aircrew withstanding a successful 450-knot ejection in any of four current USAF & USN tactical aircraft platforms.
