ANALYSIS OF THE KINEMATIC SCHEME OF AN AIRCRAFT PISTON W-SHAPED ENGINE WITH TRAILER CONNECTING RODS

This article presents the analysis and results of analytical, calculation, design solutions for development piston engines aircraft (tractors, automobiles, etc.). The authors propose an original a W-shaped engine with trailer connecting rods made comparative features. main feature is significant reduction in length, and, consequently, length crankshaft. As known, manufacturing internal combustion crankshafts long, complex, expensive procedure requiring number operations its mechanical heat treatment. An important aspect crankshaft calculation tension, torsional vibrations, hydraulic performance evaluation rod bearing, including balancing as whole. At end operating schemes section are presented (the consists four pistons, two bearing kinematically connected to one crankpin). differences from classical crank-connecting mechanism (CCM) allow us accordance technical requirements. For example, maximum power can be achieved by using variant “A”, increase stress parts cylinder-piston group (CPG), when organized according variants “B” or “C”, loading CCM increased, but CPG reduced. Considering that trailed has same stroke side cylinders workflow pattern each cylinder identical moved at rotation angle – which allows designed above characteristics such significantly expanded due electronic control. consider continuation work implementation full set studies taking into account features CCM.
