A detailed review of USAF Stability and Control Datcom methodologies was conducted to determine their validity for application to straight tapered, sweptforward wing configurations. To the extent possible the format found in the Datcom is repeated in this report. Several methods were modified to enable more accurate coefficient prediction (e.g., Wing Zero-Lift Angle of Attack, Downwash and Yawing Moment due to Yaw Rate) irrespective of sweep sign. At supersonic speeds, the reversibility theorem enabled most methodologies to be used without any modifications to account for sweptforward leading-edge designs. For the methodologies validated, sweptforward-wing estimation results were generally as accurate as the sweptback-wing results presented in the Datcom. Unfortunately, lack of test data prevented validation of several empirical methodologies (e.g., Subsonic High Angle-of-Attack Pitching Moment and Transonic Pitching Moment). No estimation methodologies are proposed in these cases.

Aircraft safety is a function of several parameters including flight stability and control. An air vehicle must be stable if it is to remain in flight. Moreover, it must be controllable as well as trimmable. This book delivers the fundamental concepts of stability and control, as well as their associated areas. It explains airworthiness, dynamic and static stability, longitudinal, lateral, and directional control, flight measurement devices and sensors, and control surfaces which are necessary topics to be considered during the aircraft design process. This book is mainly focused on air vehicles' stability features and control capabilities. The aircraft addressed in this book is a rigid-body point mass object. Describing the complete motion of a rigid-body aircraft, this book covers equations of motion with six degrees of freedom (DOF)
