An Experimental Study Of Hemispherical Vortex Generators For Separation Control Over A Naca-0012, David Joseph Ronald Tucker

Masters Theses

This is a study towards understanding hemispherical vortex generators (VGs) and their effectiveness on delaying flow separation over an airfoil. To be tested was whether these devices could generate a horseshoe vortex structure that effectively entrained higher momentum flow into the boundary layer over the surface of a NACA-0012 wing section. The experimental results are primarily from water tunnel experiments, but the clean configuration NACA-0012 airfoil was investigated by numerical methods in order to ascertain the potential for numerical modeling as a tool to accurately predict flow around the VGs, and as a guide for size and location optimization. At …

Low-Cost Imu Implementation Via Sensor Fusion Algorithms In The Arduino Environment, Brandon Mccarron

Aerospace Engineering

A multi-phase experiment was conducted at Cal Poly in San Luis Obispo, CA, to design a low-cost inertial measurement unit composed of a 3-axis accelerometer and 3-axis gyroscope. Utilizing the growing microprocessor software environment, a 3-axis accelerometer and 3-axis gyroscope simulated 6 degrees of freedom orientation sensing through sensor fusion. By analyzing a simple complimentary filter and a more complex Kalman filter, the outputs of each sensor were combined and took advantage of the benefits of both sensors to improved results. Gyroscopic drift was removed in the pitch and roll axes using the Kalman filter for both static and dynamic …
