Descripció:

The objective of this final thesis is to perform a comprehensive analysis of the steady-state and dynamic response of rotor blades operating in axial flight, with a particular emphasis on the three-dimensional elastic deformation of the blades. The research aims to investigate the complex interactions between aerodynamic loads and structural flexibility. Understanding these interactions is essential for optimizing aerodynamic performance, improving flight stability, and ensuring the structural integrity and reliability of rotorcraft blades under vertical flight conditions.

Objectius:

The objectives of this final project are to conduct a comprehensive literature review on rotor blade performance under axial flight conditions, calculate load distributions for rigid rotors using Blade Element Momentum Theory (BEMT), analyze the steady-state response of flexible rotors by integrating BEMT with Finite Element Analysis (FEA), extend the analysis to include the dynamic response of elastic rotor blades, explore the use of panel methods to compute aerodynamic loads and their integration into both steady-state and dynamic analysis, and compile the research findings and methodologies into a comprehensive final report.

Tasques a realitzar / Característiques:

-Literature review: Conduct a comprehensive literature review to investigate existing methodologies and techniques for rotor analysis under axial flight conditions. This will include examining past research on both rigid and elastic rotor systems, as well as the application of numerical and analytical methods in rotor dynamics. -Rigid rotor analysis: Calculate the distribution of aerodynamic loads and moments along the rotor blades using Blade Element Momentum Theory (BEMT) under steady-state conditions for a rigid rotor. This will establish a baseline understanding of load distribution without considering blade flexibility. -Flexible rotor analysis: Analyze the steady-state response of the rotor blades by integrating BEMT with Finite Element Analysis (FEA) to account for blade flexibility. This combined approach will provide insights into how flexibility influences the aerodynamic performance and structural behavior of the rotor blades. Extend the model to include time-dependent effects such as transient aerodynamic loading at rotor start-up. -Panel methods integration: Investigate the potential integration of a panel method to obtain more accurate aerodynamic pressure distributions on the blade surface and compare the results with BEMT-based solutions to assess trade-offs between accuracy and computational cost. -Compilation and documentation: Compile and document the findings, methodologies, and results of the study in a comprehensive final report. This report will detail the research process, including the literature review, rigid and elastic rotor analyses, machine learning integration, and the overall conclusions drawn from the study.
