P16121: SAE Aero Aircraft Design & Build Aerodynamics XFLR5 was the primary aerodynamics computational software utilized (Vortex-Lattice Method) ANSYS FLUENT (Navier-Stokes+Spalart Allmaras) was used to verify XFLR5 results through horizontal stabilizer analysis Stability and Control The aircraft was designed such that it had cargo-transport aircraft stability and control characteristics. Structural Design and Stress Analysis All load bearing structures are metallic to ensure structural integrity Aluminum chassis designed such that loads are transferred to spars during flight, and landing gear bear loads on ground and endure landing impact Stress analysis performed for worst-case loading scenarios on all metallic parts Left to Right: Ron Manning, Dominic Myren, Marc Protacio, Chris Jones, Matt Zielinski Objective To design, build, and test an aircraft for the Regular Class of the 2016 SAE Aero Design Competition. The aircraft serves as a development platform for the RIT Aero Design Club so that they may competitively participate in future competitions.
