Available in PDF, EPUB and Kindle. Book excerpt: Deflections and all internal forces have been calculated for concentrated static loads. Vibration modes are also presented. The effects of neglecting shearing strains in the ribs and spars and also of assuming the ribs to be rigid have been investigated by modifying the electric circuits to correspond to these simplifications.

This book was released on 1956 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new class of frequency-selective shock absorbers called band-pass shock absorbers which were conceived as a means of overcoming some of the limitations of conventional shock absorbers is described. These shock absorber designs are introduced, special emphasis being given to their use in landing and taxiing problems of high-speed aircraft. For such aircraft operated on rough land or water runways, conventional oleo struts approach a rigid condition for bum[s with steep slopes and thereby develop and transmit severe shock loads to the aircraft fuselage. The operation of the band-pass shock absorbers in the reduction of loads in certain selected frequency ranges is described. Theoretical equations are derived and solutions are made for several cases for the purpose of comparing the low-pass and conventional shock-absorber actions. The results indicate that the band-pass shock absorbers should alleviate high-frequency or rapidly applied impact loads but should retain the characteristics of conventional oleo struts when taxiing and design landing loads are slowly applied. A number of variations in design are presented for low-pass shock absorbers and reference is made to double-acting band-pass vibration absorbers for other applications.

This book was released on 1956 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of systematic approximations to the summary theory is developed for the treatment of problems too simple to merit the use of the complete summary theory, and procedures are discussed for applying the summary theory and its systematic approximations to the shimmy of more complex landing-gear structures than have previously been considered.

Download or read book Strength and Ductility of Bainitic Steels written by Donald H. Desy and published by . This book was released on 1957 with total page 898 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the factors believed to affect the strength and ductile-to-brittle transition temperature of bainitic steels, including mean ferrite path and degree of internal strain, have been studied. Strength was measured by diamond pyramid hardness, and transition temperature was obtained from a tensile impact test on small notched specimens. Seven laboratory heats of carbon-molybdenum steel and two heats of carbon steel were transformed isothermally to bainite at various temperatures and tested. Mean-ferrite-path measurements were made on electron micrographs of three of these steels. The mean ferrite path was found to have only a slight effect on the strength of bainite and no effect on the transition temperature. Preliminary measurements of X-ray line broadening indicate that the degree of internal strain may be the controlling factor in determining the strength of bainite. The transition temperatures of the bainites fell within a band between -80 and -160 degrees C and did not vary regularly with hardness, carbon or alloy content, or mean ferrite path. In the SAE 1062 steel at high strength levels, bainite has a transition temperature lower than that of tempered martensite at the same strength level.
