THE SUPPORT PROCESS, SIMULATION RESEARCH DESIGN AND STRUCTURE OF THE NEW HELICOPTER’S CONSTRUCTION SCHEMATICS WITH SPECIAL EMPHASIS ON GROUND RESONANCE PHENOMENON

摘要

During design work on the new constructionof a light unmanned helicopter an attempt wasmade to map the actual design of the helicopterand built the helicopter mode using the finiteelement method. Calculations made using thismethod were intended as a support forconstruction work. In addition, this model couldbe used as a simulator for the real resonancetests and the first attempts to disassemble therotor. Such an approach to the design andtesting of the real structure allowed us toexamine in detail the dangers that may occurwhen tested on a real object. The main reasonsfor using the model were to determine thenatural frequency of the structure, reproductionattempts resonance (excitation harmonic force)simulations of the rotor to detach from zero tonominal speed and landing simulations ofasymmetric structures on the ground.
