Helicopter rotors in flight constitute a fairly complex wing geometry and exhibit motion in several axes. As a result, rotor motion creates quite complex flow patterns, and unlike fixed wings, flow around each rotor blade interacts with each other. These complexities make the analysis of the rotor flow is a challenge for CFD solvers. The challenge starts with very high requirements on the quality of the computational mesh. A modern helicopter rotor involves a number of different airfoil sections, complex profile blending, twists and other complexities. Moreover, blade tip geometry can be selected from a wide variety of candidates. In this study, we present the results of our fully automatized rotor geometry and solution domain generation tool. With the new tool a rotor with a very high complexity with any number of blades can be generated, and a very high quality multi-block and conformal meshes are produced. The new tool is tested with known helicopter rotors and CFD solutions are calculated.

An automatic geometry and mesh generation tool for helicopter rotor aerodynamic design and analysis Uzun, Halit Eldem; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2021-9-08) Helicopter rotors in various flight regimes constitute a fairly complex wing geometry and exhibit motion affected by the rotor wake with strong tip vortices. As a result, rotor motion creates highly three-dimensional flow patterns, and unlike fixed wings, flow around each rotor blade interacts with each other. Due to these complexities, the rotor flow analysis can be very challenging for CFD solvers. The challenge starts with very high-quality requirements on the computational mesh around the rotor geometry...
Development of a comprehensive and modular modelling, analysis and simulation tool for helicopters Yücekayalı, Arda; Kutay, Ali Türker; Department of Aerospace Engineering (2011) Helicopter flight dynamic, rotor aerodynamic and dynamic analyses activities have been a great dispute since the first helicopters, at both design and test stages. Predicting rotor aerodynamic and dynamic characteristics, helicopter dynamic behavior and trimmed flight conditions is a huge challenge to engineers as it involves the tradeoff between accuracy, fidelity, complexity and computational cost. Flight dynamic activities such as; predicting trim conditions, helicopter dynamic behavior and simulation of...
Co-cured manufacturing of advanced composite materials using vacuum assisted resin transfer molding Akın, Mert; Güvenç Yazıcıoğlu, Almıla; Department of Mechanical Engineering (2018) Sub-structures of aircraft structures mainly consist of stiffened shells such as fuselage frames, ribs, and multi-cell box beams. Conventionally, these stiffened shells are manufactured through a process wherein shells and stiffeners are fabricated separately and then are integrated either through mechanical fastening or adhesive bonding. Co-curing is an integral molding technique that can greatly reduce the part count and the final assembly costs for composite materials. In this study, a low-cost co-curing...
Development of a multigrid accelerated euler solver on adaptively refined two- and three-dimensional cartesian grids Çakmak, Mehtap; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2009) Cartesian grids offer a valuable option to simulate aerodynamic flows around complex geometries such as multi-element airfoils, aircrafts, and rockets. Therefore, an adaptively-refined Cartesian grid generator and Euler solver are developed. For the mesh generation part of the algorithm, dynamic data structures are used to determine connectivity information between cells and uniform mesh is created in the domain. Marching squares and cubes algorithms are used to form interfaces of cut and split cells. Geome...
Designing autopilot and guidance algorithms to control translational and rotational dynamics of a fixed wing VTOL UAV Güçlü, Anı; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2020) Guidance and autopilot algorithms are designed and applied to a fixed wing VTOL air vehicle. The algorithms are developed on a rotary wing and a fixed air vehicle. Each air vehicle is identified by experimentation to reduce the discrepancies among the system model and the actual air vehicles. Designed controllers for the air vehicles are deployed to Pixhawk Cube controller board. Indoor and outdoor flight tests are carried out. For the rotary wing air vehicle, active disturbance rejection control algorithms...
