Abstract : The long range Maritime Patrol mission has evolved and expanded such that the U. S. Navy's maritime patrol aircraft (P-3C Orion) has become an attractive platform from which to employ a wide variety of air launched weapons. Specifically the need for a stand alone air-to-air defensive capability was identified. In 1989 the Naval Air Test Center at Patuxent River, Maryland began investigations for this through the P-3C/AIM-9 integration program. Naval Postgraduate School responded to this with the construction of a ground vibration test stand and the conduction of a preliminary vibrational characterization of the AIM-9 missile. From these tests a two degree of freedom lumped mass model was developed along with the determination of the primary and secondary missile resonate modes in pitch. In addition, a mathematical model of the AIM-9 missile was developed using finite element techniques. This model was used to analytically determine the modal parameters of the missile and set up a modal parameters of the missile and set up a model test system to experimentally verify the model parameters in view of natural frequencies, mode shapes and transient response....
