Abstract

The paper presents a discussion of the design, development, and assembly of Structural Health Monitoring (SHM) experiments launched in space on a sub-orbital flight. Onboard experiments were focused on investigating the utility of piezoelectric wafer active sensors (PWAS) as active elements of spacecraft SHM systems and the electro-mechanical impedance method as a promising SHM methodology for space systems. A Magneto-elastic active sensor (MEAS) was used to record in-flight dynamics of the payload. The list of PWAS experiments included a bolted-joint experiment, an adhesive endurance experiment, and an experiment to monitor PWAS condition during spaceflight. Electromechanical impedances of piezoelectric sensors were recorded in-flight at varying input frequencies using onboard microcontroller units. PWAS and MEAS data were recovered from the payload after landing. Details of the sub-orbital flight experiments are considered and conclusions pertaining to flight results are presented. The paper discusses issues encountered during design, development, and assembly of the payload and aspects central to successful demonstration of the SHM during sub-orbital space flight.
