Available in PDF, EPUB and Kindle. Book excerpt: A general theory of solid-state diffusion in strained systems is developed on a molecular-kinetic basis. The theory predicts that for simple strains the diffusion coefficient is an exponential function of the lattice parameter and that the rate of change of the diffusion coefficient with strain is linearly related to the interatomic forces. It has also been shown that for plastic flow the diffusion coefficient is a linear function of strain rate. All the conclusions are confirmed by the data available in the literature.

Jaquet and published by . This book was released on 1955 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regardless of the aspect ratio of the wing, the addition of and increase in size of the horizontal ducts caused an increase in directional stability for complete models or a decrease in instability for tail-off configurations at low and moderate angles of attack. The addition of and increase in size of vertical ducts on the models with the wing of aspect ratio 2, however, resulted in large decreases in directional stability which were about constant for the angle-of-attack range investigated.

This book was released on 1971 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic characteristics of a full scale executive type jet transport aircraft with a T-tail were investigated in a 40 x 80 ft (12.2 by 24.4 meter) wind tunnel (subsonic). Static, longitudinal, and lateral stability, and control characteristics were determined at angles of attack from -2 deg to 42 deg. The aircraft wing had 13 deg of sweep and an aspect ratio of 5.02. The aircraft was tested power off with various wing leading- and trailing-edge high lift devices. The basic configuration was tested with and without such components as engine nacelles, wing tip tanks, and empannage. Hinge-moment data were obtained and downwash angles in the horizontal-tail plane location were calculated. The data were obtained at Reynolds numbers of 4.1 million and 8.7 million based on mean aerodynamic chord. The model had static longitudinal stability through initial stall. Severe tail buffet occurred near the angle of attack for maximum lift. Above initial stall the aircraft had pronounced pitch-up, characteristic of T-tail configurations. A stable trim point was possible at angles of attack between 30 deg and 40 deg (depending on c.g. location and flap setting). Hinge-moment data showed no regions with adverse effects on stick force. Comparisons of wind-tunnel data and flight-test are presented.

Jaquet and published by . This book was released on 1957 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the Langley stability tunnel to determine the effects of ventral fins at two positions (zero and -70 degrees dihedral) on the lateral stability derivatives of a 45 degrees swept high-wing model oscillating in yaw. The effect of the ventral fins on the stability derivatives was determined with and without the vertical and horizontal tails for an angle-of-attack range of zero to 30 degrees at a Mach number of 0.13 and a Reynolds number of 830,000, based on the wing mean aerodynamic chord. The steady-state derivatives for a similar model without ventral fins are also presented. No discussion of the data has been made in order to expedite their publication.
