Spin-Yaw Lock-In of a Rotationally Symmetric Missile
Autor: William H. Mermagen, Charles H. Murphy
Publikováno v: Journal of Guidance, Control, and Dynamics. 32:378-383
Spin―yaw lock-in has usually been associated with small aerodynamic asymmetries that produce a trim angle that rotates with the missile. Recent trajectory calculations using wind-tunnel measurements ofthe aerodynamic moment acting on a rotationally

Flight Motion of a Continuously Elastic Finned Missile
Autor: William H. Mermagen, Charles H. Murphy
Publikováno v: Journal of Guidance, Control, and Dynamics. 26:89-98
The motion of elastic finned projectiles has been analyzed by various approximate theories. In this report the exact equations of small amplitude motion are derived for a symmetric missile. The aerodynamic and elastic symmetries are used to allow the

Flight mechanics of an elastic symmetric missile
Autor: William H. Mermagen, Charles H. Murphy
Publikováno v: Journal of Guidance, Control, and Dynamics. 24:1125-1132
The free-flight motion of an elastic missile is approximated with three bodies connected by two massless elastic cantilever beams. If the mass distribution of the three bodies is 1-2-1, the frequency of the symmetric oscillation of the outer bodies i

Integrating Technology into the Meteorology Classroom: A Summary of the 1993 Northeast Regional Unidata Workshop
Autor: Charles H. Murphy, Russell De Souza, Gregory P. Byrd, William Fingerhut
Publikováno v: Bulletin of the American Meteorological Society. 75:1677-1683
This article summarizes the first Northeast Regional Unidata Users' Workshop, held 17–19 August 1993 at the State University of New York College at Brockport. The goal of the workshop was to provide a forum where users could exchange ideas and upda

Spin-yaw Lockin of an Elastic Finned Projectile
Autor: Charles H. Murphy, William H. Mermagen
Publikováno v: AIAA Atmospheric Flight Mechanics Conference and Exhibit.
Supersonic finned projectiles carrying very long dense metallic rods have been observed to have significantly large flexing motion. The appropriate Lagrangian for a pitching, yawing, rolling, and flexing missile is derived, and the finite element met

Symptom of payload-induced flight instability
Autor: Charles H. Murphy
Publikováno v: Journal of Guidance, Control, and Dynamics. 15:1038-1040
Observations of instability caused by a moving payload--liquid or solid--have shown that large angular motions are always accompanied by a large spin-down moment. A simple general relation is derived between the side moment and the spin moment caused
