Results show that effects do not produce additional periodic blade moments, except when accompanied by center of gravity accelerations, significant to fatigue calculations during principal part of flying time; therefore, time spent in various flight conditions, as determined by NACA helicopter VGHN recorder, can be used for that part of cumulative fatigue analysis involving largest number of cycles in distinction to largest stresses.
