Abstract

The features ofthe external loadscalculation underkinematicandpoweranalysis ofspatial mechanical systemsofcompositematerials are considered. For eachtype of aircraftaeromechanicalscheme there is its own systemof power and moments, which has its ownfundamental differences.In terms ofsystem of equations solutionsof associatedobjects movementaeromechanicalschemeof aircraftis consideredas a systemof objects associated by boundary conditionsin three-dimensional space. Given setof models allowsto calculate thetypicalprofile ofa light helicopterflightwith simultaneouskinematicandpoweranalysis ofcontrol system of two-bladedrotor. There are madecalculations of fluttercharacteristics ofmain rotor bladewith simultaneousevaluationof the torsionhub deflected mode.

Keywords:
