EQUATIONS of motion have been derived and used to investigate analytically lateral and directional maneuverability characteristics of an advanced airship configuration consisting of auxiliary aerodynamic and powered yaw control augmentation. Theoretical expressions for turning radius, sideslip angle, roll angle, and the corresponding rudder deflection or auxiliary control needed in a steady turn have been obtained in terms of vehicle geometry, stability, control, and flight parameters. These theoretical results are also analyzed and shown to agree with experimental observations of the past. Potential for improving vehicle maneuverability either by relaxing its inherent static stability or by use of auxiliary yaw controls is discussed and illustrated with an example 2.8million ft3 airship.
