Group 3Heavy Lift Cargo Plane William Gerboth, Jonathan Landis, Scott Munro, Harold Pahlck December 21, 2009
Presentation Outline • Project Objectives • Competition Update • Phase I Summary • Phase II Summary • Design Approaches • Technical Analysis • Equipment Selection • Prototype Fabrication Plan • Updated Budget • Nugget Charts
Project Objectives • Design and build an airplane to successfully compete in the SAE Aero East competition • Plane must successfully take off from a runway of 200 feet and land on a runway 400 feet • Constraints of 55 pounds total weight, and the combined height, length, and width of 200 inches • Plane must make one complete 360° circuit of the field per attempt
Competition Updates • Aero Design East competition is full • As of now Aero West is still open • In order to compete • Submission of design report with plans and payload prediction before January 21, 2010 • Aircraft must be constructed and tested by February 22, 2010 • Decision not to compete • Time needed to complete report and construct airplane
Phase I Summary • Design concepts were decided upon • Airfoil Shape: Eppler 423 • Wing Shape: Straight • Landing Gear: Tricycle • Tail shape: T-Tail
Phase II Summary • Calculated drag, lift, takeoff distance, & landing distance • Used equations from textbooks, White paper, online • Drag • Takeoff • Landing
Design Approaches • CL vs. Angle of Attack • CL available from Eppler 423 • Determined flap angle of 8 deg. to prevent stall • CL,max = 1.4
Technical Analysis: Wing Loading • Wing subject lift force • Non uniform distributed load • 22.5 lbs per wing • Max Stress = 886 psi • Yield Strength = 2000 psi • Max Displacement = 1.57 in
Technical Analysis: Fuselage Loading • Fuselage tested for relative strength • Cantilever static analysis done • Force of 1 lb used to test strength in x-y and x-z directions • Max Stressx-y= 314 psi • Max Stressx-z= 156 psi • Max Displacementx-y = .084 in. • Max Displacementx-z= .083 in.
Technical Analysis: Tail Analysis • The tail was analyzed for withstanding a 3ft drop and drag forces • Max Stress: 290 PSI • Max Displacement: .046 in
Technical Analysis: Landing Gear • Landing gear tested to withstand a 3ft drop • Max Stress: 22,874 PSI • Max Displacement: .023 in
Technical Analysis: Stability & Control • Longitudinal Static Stability • Criteria: Static Margin Must be Positive • Static Margin = hn- h • Neutral Point = hn = • Tail Volume Ratio = • Center of Gravity = h • Solidworks Used to Calculate C.G
Equipment Selection • Engine • O.S. .61FX with E-4010 Muffler • Fuel Tank • Great Planes Fuel Tank 12 oz. • Propeller • APC 14x4W Propeller • Servos • 5G TowerPro SG50 Micro RC Servos
Plan for Phase IV • Do further analysis on final design • Build and analyze a small scale airfoil for testing in the wind tunnel • Begin construction • Devise a testing plan
