A lack of in-flight data for the Evolved Expendable Launch Vehicle Secondary Payload Adapter has prevented engineers from efficiently producing more inexpensive satellites and adapters. Designing and Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) Launch Load Module (ELM) capable of recording in-flight accelerations, temperatures, strain, and sound pressure will provide industry with actual conditions to design for. The weight of the ELM is minimized while maintaining a stiffness above 500 Hz, as to not adversely effect the other aspects of the mission. Shaker table testing will be done to verify this requirement. It attaches to one adapter port and extends inward. The design is a 13.5 inch diameter shell constructed of 6061 aluminum, which can house necessary measurement devices. All data will be recorded and stored onboard, then transmitted back to ground receiving stations after all satellites have been jettisoned. Santa Clara University has provided the necessary data acquisition system and electronic components.
