An aeroelastic study of cycloidal rotors used in various configurations Description détaillée : aeroelastic study of cycloidal rotors Developed multibody dynamics models using the MBDyn multibody software for mission analysis of a Heligyro, a Helicopter, and a Quadricyclogyro: 1. optimized using numerical genetic minimization approach; 2. relied on both Gnu Octave and Dakota for serial and parallel optimizations; 3. with vibration/comfort control using filters into the controller algorithm; 4. each aerial vehicle can fly totally autonomously; 5. limited dimensions to a compact Heligyro and thus need strong cycloidal rotors to produce adequate torque; 6. rotor weight estimation based on gross estimates or 3D printed plastic materials. Setup a cycloidal rotor CFD model for the car-rotor configuration, the Cyclomobile, which is ready for optimization or implementation of a faster CFD method. Conducted preliminary tests for the fabrication of a 3D printed cycloidal rotor and small drone: 1. 3D printing tests with nylon and PLA; 2. dimensioned the rotor by optimization of the aerodynamic analytic equations; 3. set up an hybrid gradient-based optimization of the drone analytic dimensioning using SageMath mathematical toolkit and Dakota.
