Book Description
Air-flow characteristics behind wings and wing-body combinations are described and are related to the downwash at specific tail locations for unseparated and separated flow conditions. The effects of various parameters and control devices on the air-flow characteristics and tail contribution are analyzed and demonstrated. An attempt has been made to summarize certain data in a form useful for design. The experimental data herein were obtained mostly at Reynolds numbers greater than 4 x 105 and at Mach numbers less than 0.25.

Summary and Analysis of Horizontal-tail Contribution to Longitudinal Stability of Swept-wing Airplanes at Low Speeds

Category : Airplanes
Languages : en
Pages : 133
Book Description
Available wind-tunnel data on the low-speed horizontal-tail contribution to the static longitudinal stability of high-speed airplane configurations incorporating unswept and sweptback wings are reviewed and analyzed. The characteristics of the flow behind wings and wing-body combinations are described and related to the downwash at specific tail locations for unseparated flow conditions. The effects of variations of tail position, variations of wing plan form and airfoil section, trailing-edge flaps, stall-control devices, and ground interference on the air-flow characteristics and tail contribution are analyzed and demonstrated. The more favorable tail arrangements are emphasized and their application to specific configurations is illustrated. The analysis of the factors affecting the horizontal-tail contribution is, for the most part, descriptive; however, an attempt has been made to summarize certain data by empirical correlation or theoretical means in a form useful for design.

The Theory of Diffusion in Strained Systems
Author: Louis A. Girifalco
Publisher:
ISBN:
Category : Crystals
Languages : en
Pages : 1082
Book Description
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.
