Even if there are a number of books in print facing elasticity, many specialise in really good themes reminiscent of mathematical foundations, anisotropic fabrics, two-dimensional difficulties, thermoelasticity, non-linear concept, and so forth. As such they don't seem to be applicable applicants for a common textbook. This e-book offers a concise and arranged presentation and improvement of basic thought of elasticity.
Written via Ivan Jurilj - a grasp of Aeronautical Engineering and previous Air strength Officer, this ebook is making an attempt to bare crucial episodes of the superb historical past of global aviation. even as it truly is desirous about describing how plane advanced, from its earliest days to trendy occasions. either army and civil airplanes went via incredible alterations throughout the interval of “only” a hundred and ten years - from fragile flying machines scuffling with to stick airborne, to effective rulers of the sky in a position to flying a lot speedier than the rate of sound, to arrive the sting of area and have the ability to convey continents to time distances of just a couple of hours.

The resulting characteristics of the propeller show the slight decrease of the propeller thrust due to the yaw angle up to the angle of 10 degrees. For the angle of 30 degrees, the thrust reduction reached approximately 10%. 3 Main developments (1960s) The main developments in the experimental research on whirl flutter were accomplished in the early 1960s in direct connection with the Electras accidents. The experiments are divided into two main categories. In the first category are simple tests on the models of the flexibly attached propeller in the windmilling mode.
The hinge points were adjustable as well. 3. Regarding the pitch and yaw stiffness ratio, the model was close to unity. 4 as the dependence of the required stiffness on the dynamic pressure. The complex investigations were conducted by Bland and Bennett  in NASA Langley wind tunnel. They were investigating the aerodynamic forces on the propeller – nacelle model and measured the whirl flutter characteristics. The propeller rotating in the windmilling mode was attached by the shaft through a hinge allowing pitch and yaw with adjustable flexibilities.
First, the starboard nacelle tore away and rammed into the horizontal tail. Consequently, the outer part of the starboard wing was torn away, the aircraft started to pitch and roll and finally fell into the ocean upside down. Several parts of the wreckage were recovered; unfortunately the black boxes were not found. In addition to the other things the investigators used to explain the causes and the course of the events, the voice record from the cabin was used. This record contained acoustic signals indicating the late stage of growing fatigue cracks and the subsequent structural destruction .
