This book was released on 1968 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of an experimental investigation to determine the lateral/directional stability characteristics of a four-propeller tilt-wing VTOL aircraft using a one-tenth scale dynamically similar model are presented. Test conditions include wing incidences of 89, 70, and 30 deg. Measurements of the transient motion of the model in the lateral/directional degrees of freedom and the static lateral/directional stability derivatives were made. The transient and steady-state data are analyzed assuming that the motions of the vehicle may be described by linearized equations, and the resulting static and dynamic derivatives are presented. The characteristics of the lateral/directional dynamic motion of the full-scale vehicle as predicted by the tests of the dynamically similar model are determined and discussed. All data are presented for a center-of-gravity position of 9-percent MAC, which is ahead of the most forward C.G. position of the aircraft (15-percent MAC), and the horizontal tail and flap programs differ from those presently used on the aircraft.

This book was released on 1967 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of experiments conducted to evaluate the longitudinal stability characteristics of a 1/10 scale dynamic model of a four-propeller tilt-wing VTOL transport are presented and discussed. The Princeton Dynamic Model Track was used to measure the static stability and the transient response of the model at wing incidences from 90 degrees to 40 degrees. The results are interpreted in terms of full-scale aircraft characteristics. All data are presented for a C.G. position of 90% MAC (the most forward C.G. position of the aircraft is 15% MAC) and the horizontal tail and flap program differ from those presently used on the aircraft. The transient motions at wing incidences above 70 degrees were similar and dominated by high speed stability and low angular damping resulting in an unstable oscillation of approximately a 9-second period for the full-scale aircraft. The responses at wing incidences below 70 degrees were more complex due to a rapid decrease in the speed stability from a large positive value above 70 degrees to a negative value at 60 degrees. The values of the speed stability for the aircraft determined by a detailed analysis of the data in the neighborhood of 60 degrees wing incidence differ from those obtained from a preliminary analysis of the data by the LTV Aerospace Corporation. Typically, at wing incidences between 60 degrees and 40 degrees the linearized static stability derivatives M sub u and M sub alpha were small, nonlinearities were evident, and the small amplitude linearized motion was dominated by a divergence. At 40 degrees wing incidence, indications were that the dynamic motions were becoming stable. (Author).
