The revolutionary all-metal monoplanes designed during WWI under the direction of Professor Hugo Junkers were the progenitors of a long and incredibly successful line of aeroplanes. The J.9/D.I monoplane arrived too late to influence the fortunes of the German Army Air Service and any operational activities were limited to postwar fighting in Poland yet it is deserving of an important position in German military aviation history. In a period of wooden, wire-braced, fabric-covered biplanes and triplanes, the products of Junkers Werke stand apart as being ahead of their time in several respects.

Structural Acoustics and Vibration presents the modeling of vibrations of complex structures coupled with acoustic fluids in the low and medium frequency ranges. It is devoted to mechanical models, variationalformulations and discretization for calculating linear vibrations in the frequency domain of complex structures. The book includes theoretical formulations which are directly applicable to develop computer codes for the numerical simulation of complex systems, and gives a general scientific strategy to solve various complex structural acoustics problems in different areas such as spacecraft, aircraft, automobiles, and naval structures. The researcher may directly apply the material of the book to practical problems such as acoustic pollution, the comfort of passengers, and acoustic loads induced by propellers.
Structural Acoustics and Vibration considers the mechanical and numerical aspects of the problem, and gives original solutions to the predictability of vibrations of complex structures interacting with internal and external, liquid and gaseous fluids. It is a self-contained general synthesis with a didactic presentation and fills the gap between analytical methods applied to simple geometries and statistical methods, which are useful in high frequency structural acoustic problems.

Eglin Air Force Base is a United States Air Force base located 1-mile (1.6 km) southwest of Valparaiso in Okaloosa County, Florida, United States. It was named in honor of World War I aviator and test pilot Lt Col Frederick Irving Eglin. Since its founding in 1933 Eglin has evolved from a remote bombing and gunnery range in the 1930s (although very little actual bombing was done at the outset) into the military's primary non-nuclear test facility, it now supports a wide variety of multi-service test missions as well as providing a home for many special operations functions.
The Osprey Superbase series takes the enthusiast behind the scenes on the world's major air bases. This up-front series features spectacular, exclusive colour photography from aviation's camera sharpshooters. If you want to get inside the perimeter fence to see combat aircraft in their natural habitat, the Superbase series is literally where it's at.
