Study of CH-53A Helicopter Flight Load Parameters

Abstract

A flight loads survey was performed on four CH-53A helicopters to determine whether design limits were being exceeded under actual operating conditions in the field. The survey obtained a total of 133.40 hours of valid flight data in 1968 - 1969. By means of recording oscillographs, analog records were obtained for airspeed, altitude, outside air temperature, normal acceleration, rotary wing RPM, cruise guide indication, engine torque, and landing/take-off indication. The report presents a reduction of these data in the form of histograms, graphs and tables.
