This thesis presents a versatile, dynamic rotor/propeller model for various all-electric and hybrid-electric vertical takeoff and landing aircraft (eVTOL) simulation applications. The goal is to reflect the transformative potential of eVTOL to carry different types of thrust sources using one generic mathematical model. The thrust sources may include propellers, articulated rotors, ducted rotors, and coaxial rotors. These rotors are modeled based on blade element theory. Rotor inflow is estimated using the uniform dynamic inflow model or Pitt-Peters dynamic inflow model. They are interchangeable based on the application's fidelity and complexity. The dynamic rotor/propeller model allows to position and orient multiple rotors and propellers in any desired configuration. This model can be used during the conceptual design phase in isolated rotor simulations, performance calculations, stability analyses, sensitivity analyses, optimization, and trade studies for eVTOL applications since it is an all-parametric and computationally robust tool. The model outputs are compared with the wind tunnel test data of the isolated rotors found in the literature. Simulation results of an example complex multi-rotor eVTOL are shown and discussed.

A Dynamic Field Theory Based Pilot Model To Control Aircraft Pitch Attitudes Yasin, Kaygusuz; Çakır, Murat Perit (null; 2015-09-25) In this study, a dynamic field theory (DFT) based cognitive model of a pilot performing pitch attitude control of a 3 degree of freedom aircraft model is presented. The cognitive model is validated by comparing the pilot model’s pitch attitude hold performance with real flight test results of a human pilot on a real aircraft. A high degree of similarity was observed between the behaviour of the human pilot and the DFT model. The paper contains a brief summary of older control theory based pilot models, desc...
A Computational analysis on rotor-propeller arm interaction in hovering flight Yener, Serkan.; Perçin, Mustafa; Department of Aerospace Engineering (2019) This study presents a computational analysis on the interaction between rotor and different rotor frame-arm geometries in hovering flight. The influence of the frame arm on the aerodynamic performance of the rotor is assessed by using commercially available computational fluid dynamics (CFD) solver software ANSYS Inc. Fluent 17. Numerical results are validated for hovering and forward vertical climb flight conditions with thrust and torque measurements conducted on a 16x4 carbon fiber propeller. The thrust ...
A new method to determine dynamically equivalent finite element models of aircraft structures from modal test data Karaağaçlı, Taylan; Yıldız, Erdinç N.; Özgüven, Hasan Nevzat (Elsevier BV, 2012-8) Flutter analysis is a major requirement to predict safe flight envelops and to decide on flutter testing conditions of newly designed or modified aircraft structures. In order to achieve reliable flutter analysis of an aircraft structure, it is necessary to obtain a good correlation between its finite element (FE) model and experimental modal data. Currently available model updating methods require construction of a detailed initial FE model in order to achieve convergence of the modes obtained from updated...
Optimal Design of a Miniature Quad Tilt Rotor UAV Kahvecioglu, Ahmet Caner; Alemdaroglu, Nafiz (2015-06-12) This paper describes the design procedure of a convertible miniature (mini and micro) quad tilt rotor unmanned air vehicle (UAV), which has about 2 meters of wing span, one hour of mission time and 5 kilograms of total weight. The aircraft is driven by four brushless direct current motors, and the structure of it completely made of composite materials. When the wing and tail of the aircraft are dismounted, it operates as a quad- rotor with tilting rotors. The aircraft is planned to carry a gimbal camera wei...
A Computationally Efficient Appearance-Based Algorithm for Geospatial Object Detection Arslan, Duygu; Alatan, Abdullah Aydın (2012-04-27) A computationally efficient appearance-based algorithm for geospatial object detection is presented and evaluated specifically for aircraft detection from satellite imagery. An aircraft operator exploiting the edge information via gray level differences between the aircraft and its background is constructed with Haar-like polygon regions by using the shape information of the aircraft as an invariant. Fast evaluation of the aircraft operator is achieved by means of integral image. Rotated integral images are...
