Help diagnosing NVH

Post by CShackelford »

Hello. Can somebody help me understand what I am looking at when viewing vibration indices on the NVH during this test run. From what I can tell, its picking up mostly first-order propeller vibrations in this test run. The vibration occurs under hard acceleration on initial pickup. Additionally, at around 75mph there is a noticeable howl.
