Anomaly Detection for Hybrid Rocket Bench Tests

Kurzfassung

During a bench test of a hybrid rocket engine , noticeable unsteadiness of the exhaust plume was observed which was later found to be caused by a defect in the heat shield of the post-combustion chamber. Using videos of the experiment, several anomaly events can be identified. This poster presents ongoing efforts to automatically detect these events in the sensor data measured during the experiment. To this end, several anomaly detection algorithms are evaluated on this dataset, in order to find potential approaches for live monitoring of future bench tests.
