The ATEK flight experiment was successfully launched on 13th July 2019 from the launch site Esrange
in Kiruna and provided valuable flight data. The second stage and the payload reached an apogee of
approx. 240 km and continued the descent without any thrust and landed approx. 500 seconds after
the take-off at a distance of approx. 67 km from the launch site. The payload was decelerated in the
late subsonic flight phase using a parachute to avoid a hard impact on ground after a 800 seconds
flight time. The Health Monitoring System allowed the measurement of aerothermal and mechanical
loads on the hybrid payload structure, motor adapter, motor case, tail can and fins along the complete
flight. Part of the data has been transmitted during flight to ground via telemetry at a low sampling
rate of several Hertz. In addition, several impact-resistant data acquisition units could acquire the data
at a high sampling rate of several Kilohertz and stored it onboard. The hybrid payload structure and
health monitoring data acquisition units have been recovered after the flight and showed complete
functionality.
