Data Challenge for HUMS2025 Now Open

This new Data Challenge for HUMS2025 utilizes a dataset generated from the Bell 206B-1 Kiowa (OH-58) helicopter main rotor gearbox test program in our Helicopter Teansmission Test Facility (HTTF) at DSTG Melbourne.

This time the challenge is to detect and trend a rare/critical failure mode where a fatigue crack has propagated within the gearbox casing. The gearbox casing crack is shown in Figure 1 below.

The dataset was released to challengers from 21st August to 31st October 2024, and contains vibration data from the 86 load cycles of the test. Each load cycle of the test consisted of running the gearbox for 20 minutes at the following percentages of the rated maximum load (in order):

100%,
125%,
150%, and,
125% again before repeating

Both raw vibration, and pinion/bevel hunting-tooth synchronous signal averages (H-SSA) data are available as follows:

1830 H-SSA data files available at all three load levels
204 selected raw vibration data files are available at the 100% rated load, and
210 available at the 125% rated load.

**Figure 1:** The cracked gearbox with the casing crack indicated by the red arrow and the Ring-Front vibration sensor is in the red circle shown as an orientation reference. A mirror was on the left hand side of the picture.

Participants are challenged to use any methodology available to them to use this dataset to detect and trend this fault. Each team is allowed one entry to the data Challenge, and at least one team member will need to present their approach and results at the HUMS2025 Conference. The winning team will be awarded a cash prize of $1 000 AUD, and both the winner and runner-up will receive a certificate.

Only registered challengers are able to download the datasets. Registration was only available until 31st October 2024 at HUMS2025 Data Challenge (DSTG—Access Our Technology).

If there are questions about the test or the dataset, please email questions to DSTG.HUMSConference@defence.gov.au
Responses will be posted to the Questions–Answers section, to ensure they are visible to all participants.
