I have had a lifelong interest in aviation, propulsion, and engineering -- ever since I first used CAD at the age of 14 to design and build a radio-controlled airplane.I am specialized in UAV-related aero/mechanical engineering, but I also have a wide range of knowledge and experience working with many types of devices and machines.Favorite Quotes:"Would those saying "It Can't Be Done" please keep out of the way of Those Doing It." - unknown"Simplicate and add lightness." - William Bushnell Stout, designer of the Ford TrimotorSKILL SETS:CAD:Creo/Pro-Engineer, SolidWorks, AutoCAD (30 years all 2D CAD), DraftSightAerodynamic Analysis:Xfoil, Xrotor, XFLR5, blade element analysis, wind tunnel testAircraft Design:Applied aero, aircraft configuration design, VTOL aircraft design, UAV designUAV Flight Control and Operations:Flight test, Part 107 certified drone pilot, Pixhawk 2.1/Cube, ArdupilotPrototyping and Production Methods:TIG and oxyfuel Welding, 3D printing, composite tooling design and fabrication, prepreg carbon fiber molding, RTM carbon fiber molding, vacuum infusion molding, carbon fiber parts, vacuum bagging, paint-in-mold parts production, manual lathe, manual millAircraft Propulsion:Variable pitch propeller design, propeller optimization (blade element analysis), propulsion acoustics, cooling system design, fuel system designOther:Designing, building, and flying radio-controlled airplanes (30 years), building and flying radio-controlled helicopters (6 years), student pilot (60 hours total, 15 hours solo), sailing yacht steering systems, sailing yacht appendage design, sailing yacht keel design
