We will have a new Data Challenge for HUMS2025 using a dataset generated from the Bell-206B1 Kiowa (OH-58) helicopter main rotor gearbox test program in our Helicopter Transmission Test Facility (HTTF) at DSTG Melbourne.

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

The data set will be released to competitors in early August 2024, and will contain vibration data from the last 86 segments of the testing regime. Each segment of the test consisted of running the gearbox for 20 minutes at the following percentages of the rated maximum load; 100%, 125%, 150%, and 125%, before repeating.  Both raw vibration, and pinion/bevel hunting-tooth synchronous signal averages (H-SSA) data sets are available, with 1830 H-SSA datasets available at all three load levels. 204 selected raw vibration files are available at the 100% rated load level, and 210 are available at 125% the rated load.

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 one team member must present their approach at the HUMS2025 Conference. The winning team will be awarded a cash prize of $1000 AUD, and both the winner and runner-up will receive a certificate.

To participate in the Data Challenge, and download the datasets, register your interest via the form below, once you have agreed to the terms and conditions, you will receive a hyperlink to download the data. If there are questions about the test or the dataset, please post these in the Question and Answer section of the HUMS2025 Data Challenge Website, to ensure they are visible to all participants.
