Aerodynamics – Wing Designs MAE 435 April 3, 2014 Status Update Presentation4

FEA Complex Wing Design MAE 435 April 3, 2014 Status Update Presentation5 Different load cases examined:  Distributed load over the surface area  Distributed load along the edge  Pointed load at the end  Natural Frequency Testing various thicknesses in different locations of the wing

Structures - Fuselage Prototype Capable of a 6.5lbf payload Light weight design~ 38g Does not need aerodynamic design 1 st iteration is designed with poster board. Final design will be carbon fiber reinforced

Structures – Four Bar Linkage MAE 435 April 3, 2014 Status Update Presentation7

Smart Materials MFC

Macro Fiber Composite Testing LabView Program for Static and Dynamic MFC Testing

Controls/Electronics The Arduino UNO was used for prototyping, and the Zduino LEE is being fitted and prepared for the fuselage. Bimorph signal generation, with fault safety, and frequency display.

Future Work Construct a wired controller Perform MFC test with Arduino controller Install Zduino LEE in fuselage
