Abstract:

From a structural flight loads program on four CH-47A cargo and transport helicopters, 235.76 hours of valid multichannel flight data were recorded as the helicopters operated from air bases in Southeast Asia. Data were processed and analyzed according to four distinct flight phases, termed mission segments 1 takeoff and ascent 2 maneuver 3 descent, flare, and landing and 4 steady state. Data are presented in the form of time and occurrence tables, histograms, and exceedance curves. These data indicate the time spent in the mission segments and parameter ranges the number of peak parameter values occurring in the ranges of the given parameter, during each of the mission segments, and in the ranges of one or more related parameters and the time to reach or exceed given maneuver and gust normal load factors.
