Download or read book Wind tunnel Study of the Effects of Propeller Operation and Flap Deflection on the Pitching Moments and Elevator Hinge Moments of a Single engine Pursuit type Airplane written by H. R. Pass and published by . This book was released on 1942 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mock-up of a pursuit airplane has been tested in the NACA full-scale wind tunnel and the effects of propeller operation and flap deflection on the aerodynamic characteristics of the wing-fuselage combination and of the horizontal tail have been determined. The results of these tests have been compared with the results of previous tests and with available theories and, in general, satisfactory comparisons have been obtained. These results have also been used to develop empirical procedures for determining the effect of propeller operation on the lift and on the pitching moments of a flapped wing and to evaluate empirical factors for calculating the downwash angles at the tail with the propeller operating. The general applicability of these empiricisms has not been determined. The elevator hinge-moment characteristics have also been determined from tests on the mock-up and indicate the inadequacy of available data on the hinge-moment parameters. The procedure for calculating stick forces from wind-tunnel data has been outlined.

Download or read book The Influence of Vertical tail Design and Direction of Propeller Rotation on Trim Characteristics of a Twin engine airplane Model with One Engine Inoperative written by Marvin Pitkin and published by . This book was released on 1945 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: Tests have been made in the Langley free-flight tunnel to determine the influence of mode of propeller rotation and vertical-tail design upon the trim characteristics of a model of a twin-engine airplane with one engine inoperative. The test model was mounted on a trim stand, which allowed freedom in roll and yaw under conditions simulating those required by the NACA and the Army Air Forces for asymmetric-power operation in flight. The seven vertical-tail designs tested included three tails of low aspect ratio and of different area, one twin tail of low aspect ratio, two tails of high aspect ratio and with different rudder areas, and one all-movable tail of high aspect ratio equipped with a linked tab. All tests were made with the flaps down.

This book was released on 1947 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the Langley 15-foot free-spinning tunnel to determine the effect of horizontal-tail position on rudder hinge-moments at attitudes simulating spinning conditions. Hinge-moment measurements were made on an unbalanced rudder on a rectangular vertical tail for six positions of the horizontail tail. The hinge-moment measurements were supplemented by tuft tests to determine the air flow about the vertical tail.
