A Dynamic Study on the Key Aspects of a Helicopter Main Transmission Systeme paper can be seen as a preliminary description of the world of helicopters, with a focus on the main transmission. Thus, the components that characterize it and the different controls to perform flight maneuvers are described. The main transmission described in the paper is a virtual prototype des

Properties and Application of Wood-Plasticcomposites Obtained by FDM 3D Printinggy. The Wood-PLA and Red-PLA materials with three layer heights were tested to determine and compare the mechanical properties of these materials. The results presented in this paper were obtained by testing specimens printed on printers using nozzles with smaller diameters. The results show that Wo

A Contribution to Theoretical-Experimental Research of Transverse Vibrations of the Axle Spindle Levis paper, an attempt was made to develop a method for their identification. The method is illustrated in the example of the axle spindle lever, and for the two variable frequency analysis, the 2D Fourier transform was used. The illustration of the procedure’s applicability was performed on its ideal
