WebJul 4, 2016 · The flight test phase of the Nasa-Army UH-60A Airloads Program was completed in February 1994. The objective of the project was to measure the airloads in flight on an UH-60A Black Hawk using 221 blade pressure transducers installed in nine radial arrays. In addition, 21 transducers were installed along the blade leading edge to … Webmodels and are used to determine the flight loads. Such models are used during the design phase of helicopters and the accuracy is generally sufficient for flight load analysis, see Ref. 11. The limit parameters can be determined from the calculated loads of the physically motivated model.
