Download or read book Investigation of Effect of Sideslip in Lateral Stability Characteristics written by Leo F. Fehlner and published by . This book was released on 1944 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: The results of tests of a circular fuselage with various combinations of tail lengths and vertical tail surfaces with and without the horizontal tail surface in the 6- by 6-foot test section of the NACA stability tunnel are reported in the form of diagrams of variation of coefficients of lateral force and yawing moment with angle of yaw and angle of attack. The results of these tests indicated that the change in the unstable yawing moment of the fuselage alone due to increased tail length did not appreciably affect the yawing moment of a fuselage and vertical-tail combination. The addition of a horizontal tail increased the efficiency of the vertical tail in normal-flight attitudes and in the region of negative angles of attack. Existing methods of computing tail effectiveness gave results within ±7 percent of the measured values for the cases computed.

Lovell and published by . This book was released on 1957 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted to determine the effects of wing position and vertical tail configuration on the stability and control characteristics of a jet-powered delta-wing vertically rising airplane model. A ducted-fan powerplant was used because there was no hot-jet powerplant of sufficiently small size and adequate reliability available. In addition to conventional flap-type control surfaces on the wings and vertical tails, the model had jet-reaction controls provided by movable eyelids at the rear of the tail pipe and by air bled from the main duct and exhausted through movable nozzles near the wing tips. The investigation consisted of flight and force tests of three model configurations: a high wing with a top-mounted vertical tail, a high wing with top- and bottom-mounted vertical tails, and a low wing with the top-mounted vertical tail. The flight tests, which were made in the Langley full-scale tunnel, represented slow constant-altitude transitions from hovering to normal unstalled forward flight.

This book was released on 1951 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented of an investigation of the low-speed static and yawing stability characteristics of a 45 degree sweptback high-wing, low-horizontal-tail configuration with various twin vertical fins located on the wing. The static and yawing stability characteristics obtained with the various twin-fin configurations are compared with the characteristics of a similar configuration with a single vertical tail at the rear of the fuselage. In addition, the effects of a small vertical fin at the rear of the fuselage on the characteristics of the twin-fin configurations are presented.

This book was released on 1951 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to determine the effects of wing position and horizontal tail position on the low speed static longitudinal and static lateral stability characteristics of airplane models having unswept and 45 deg sweptback surfaces. The results indicated that both the unswept and the sweptback low wing low-horizontal-tail configurations were the optimum configurations from the standpoint of longitudinal and lateral stability. The results indicated that, for all wing positions, moving the horizontal tail from the high to the low position resulted in configurations which were longitudinally stable throughout the angle of attack range. For the lateral case, the vertical-tail contribution to the directional stability was increased by moving the wing from the high to the low position because of the favorable sidewash at the vertical tail arising from the wing fuselage interference. The addition of a horizontal tail in the low position produced a further increase in directional stability. The results also indicated that at low angles of attack the effective dihedral due to wing-fuselage interference increased as the wing height was increased - that is, from approximately - 4 deg for the low-wing configuration to 5 deg for the high-wing configuration. This effect could be predicted with fair accuracy by available theory. At low angles of attack, the lateral force on the fuselage was increased because of the end-plate effect when a wing was placed in the high or the low position. However, the lateral force on the fuselage decreased for the low-wing configuration and increased for the high-wing configuration as the angle of attack was increased because of the variation in the distribution of sidewash on the fuselage with angle of attack.
