Book Description
Calculated simplified transfer function coefficients based on the lateral-directional equations of motion are compared with coefficients obtained by matching transient time histories with an analog computer. Aerodynamic derivatives extracted from measured transfer function coefficients are also compared with estimated derivatives. In general, good agreement between measured and estimated values was obtained.

Book Description
The lateral-directional dynamic-response characteristics of a large flexible airplane are presented for flight conlitions of 0.6 to 0.82 Mach number and an altitude of 35,OOO feet. Transient responses at various stations on the airplane to aileron and rudder pulse-type disturbances have been recorded and converted into frequency-response form. A frequency range of O.5 to 25 radians per second is presented, which includes the Dutch roll and rolling modes and also three structural modes The measured frequency responses are compared with those obtained from transfer functions based on the lateral-directional equations of motion, which include first-order effects of structural deflections. Reasonably good agreement is obtained in the low frequency range corresponding to the lateral-directional modes. However, in the higher frequency range, the effects of the structural modes are sufficiently large so that these predictions become inadequate even for the quantities measured near the center of gravity. Comparisons are also made with frequency responses obtained from transfer-function coefficients calculated for the rigid airplane to indicate the effects of flexibility. Calculated simplified transfer function coefficients based on the lateral-directional equations of motion are compared with coefficients obtained by matching transient time histories with an analog computer. Aerodynamic derivatives extracted from measured transfer function coefficients are also compared with estimated derivatives. In general, good agreement between measured and estimated values was obtained.
