Abstract : The report contains a condensed description of the X-19 V/STOL technology. The broad categories discussed include in Section I a review of the developments leading up to the X-19 program. Sections II through VI are devoted entirely to the propellers and the considerations involved in design. The radial force principle is postulated in Section II. Interference effects on the wings due to the propellers are discussed in Section III. The propeller aerodynamic design in hover and cruise is presented in Section IV. Section V is devoted to the structure and control mechanisms of the propeller. Section VI relates to the use of propellers as in airplane control device. The tandem wing principle is discussed in Section VII, covering stability, control, and drag. Section VIII is devoted solely to ground effects. The wind tunnel research activity leading up to the X-19 is presented in Section IX. The structural loads in hover, transition and cruise are discussed in Section X. Section XI presents information pertinent to landing procedures in hover or cruise in the event of power failure. A summary of the flight test program is given in Section XII, including aircraft and hardware performance characteristics. Finally, Section XIII is devoted to a general discussion and assessment of the aircraft's unorthodox features.
