Book excerpt: Summary: Tests were made in the Langley full-scale tunnel of the Grumman XF6F-4 airplane in order to investigate the factors that affect the directional stability and trim characteristics of a typical fighter-type airplane. Eight representative flight conditions were investigated in detail. The separate contributions of the wing-fuselage combination, the vertical tail, and the propeller to the directional stability of the airplane in each condition were determined. Extensive air-flow surveys of sidewash angle and dynamic-pressure ratio along a line coincident with the rudder hinge line were made for each condition investigated to aid in evaluating the slipstream effects. The data obtained from the air-flow surveys were also used to investigate methods for calculating the contribution of the vertical tail to the airplane directional stability. The results of the tests showed that, for the conditions investigated, the directional stability of the airplane was smallest for the gliding condition with flaps retracted and was greatest for the wave-off condition with flaps deflected 50°. The variation of sidewash angle at the vertical tail with angle of yaw was destabilizing for all conditions investigated. Propeller operation increased the magnitude of the destabilizing sidewash but, at small angles of yaw, also increased the dynamic pressure at the vertical tail sufficiently to make the combined effect stabilizing.

This book was released on 1951 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brief study has been made to evaluate the importance of the type of air-compression process on the loads produced on an oleo-pneumatic landing gear during impact and to determine the type of air compression process actually obtained during drop tests. A simplified analysis to determine the effect which different air-compression processes might have indicates that the value of the air-compression exponent should have relatively little effect on the landing-gear loads throughout most of the impact. The analysis of experimental data obtained in these tests shows that the polytropic exponent ranged from 1.01 to 1.10 for the condtions tested. The general trend of the data appears relatively independent of vertical contact velocity.
