The general objective was to collect and analyze aerodynamic stability and control data for the XV-4B, XV-5A, and P-1127 VTOL configurations. Correlation and analysis of existing model data were made to investigate hover and transition characteristics. Particular emphasis was placed on the aerodynamic power effects, sometimes referred to as interference effects. Other areas of investigation were sometimes referred to as interference effects. Other areas of investigation were nondimensional coefficients used to present VTOL data and wind tunnel test techniques. Wind tunnel tests were conducted using an inlet only model and a jet only model to investigate special test and analysis problems for these components. The agreement between different sets of XV-4B model data was, in general, found to be poor. However, the nondimensional coefficients used by Lockheed to reduce to XV-4B model data appear to be valid parameters for this category of VTOL airplane. The jet entrainment flow was shown by experiment to be the primary cause of the XV-4B power effects, and the XV-4B jet path was experimentally and theoretically determined.

The dominating influence of the propulsion system on the dynamic motion of a V/STOL aircraft operating in the hover or low-velocity flight modes has greatly increased the difficulty of developing such an aircraft to be stable and controllable during these modes. Small variations in stability derivatives caused by either changes in the propulsive system or errors in measurement or analytical prediction programs have been shown to cause significant changes in the dynamic characteristics of such aircraft. To better understand relationships, a program was performed using the Lockheed XV-4B jet-lift aircraft as a subject configuration. During this program, the magnitudes of ten of the stability derivatives used to describe the aircraft were varied individually, and the change in the roots of the linearized, uncoupled equations of motion noted.

From the early machines to today's sophisticated aircraft, stability and control have always been crucial considerations. In this second edition, Abzug and Larrabee again forge through the history of aviation technologies to present an informal history of the personalities and the events, the art and the science of airplane stability and control. The book includes never-before-available impressions of those active in the field, from pre-Wright brothers airplane and glider builders through to contemporary aircraft designers. Arranged thematically, the book deals with early developments, research centers, the effects of power on stability and control, the discovery of inertial coupling, the challenge of stealth aerodynamics, a look toward the future, and much more. It is profusely illustrated with photographs and figures, and includes brief biographies of noted stability and control figures along with a core bibliography. Professionals, students, and aviation enthusiasts alike will appreciate this readable history of airplane stability and control.
