Assessment and Estimation on Operation Range of Experimental Unmanned Helicopter
Main Article Content
Abstract
The object of the study is to research a Helicopter Unmanned Aerial Vehicle (HUAV) made by bilateral project HNQT/SPĐP/12.19 at Hanoi University of Science and Technology. The purpose is to study the effect of the experimental set on the aerodynamic characteristics of this unmanned helicopter and study the phenomenon of aerodynamic elasticity to provide an assessment of the durability of the model in the hovering flight mode. The one-way fluid structure interaction (FSI) method which is a combination of Computational Fluid Dynamics (CFD) and Computational Structural Dynamics (CSD), has been carried out to comprehend both aerodynamic and aeroelasticity phenomena of HUAV. The CFD results show the distribution of pressure, velocity, and turbulence in accordance with the actual phenomenon. The CSD results show displacements, stress distributions, and material limit assessments. Then, a suitable operating range that meets the feasibility and possibility of flight is created. This study is a premise for further experimental studies in the process of creating a HUAV.
