A flight loads program on a transport helicopter was conducted using a Boeing-Vertol 107-II helicopter operated by New York Airways. The following parameters were measured: airspeed, altitude, vertical load factor, pitch rate, rotor rpm, and two engine torques. Calculations based on the measured parameters included the running gross weight and rate of climb. The data were grouped into mission segments of takeoff and ascent, cruise, descent, flare and landing, and hover. After the best method of data presentation was determined, the data were sorted by parameter ranges. The primary presentation is in the form of bivariate and trivariate tables showing the time spent in each data range. Some of the more significant data effects are presented as histograms. The vertical load factor and pitch rate data are presented as exceedance and probability curves. (Author)
