[SAE Heavy Lift Cargo Plane] Joe Lojek : James Koryan : Justin Sommer : Ramy Ghaly [Ducks on a Plane] : Advisor Professor Thangam : Thursday, February 22

[Competition Requirements]  Fixed Wing Aircraft  Wing Platform Limit: 1000 squared inches  Gross Weight Limit: 55 lbs  Payload bay Specs: 4x4x16 inches rectangular block  Single unmodified O.S..61FX Engine with E-4010 Muffler  Max Take-Off: 200ft  Max Landing: 400ft  Highest Flight Score Wins Recap

[Project Review]  Team’s name:  Ducks on a Plane  Project:  Designing a remote controlled “Heavy Lift” cargo airplane.  Competition:  Society of Automotive Engineers Aero East Design Competition.  Date and Location:  May 4-6, 2007  Fort Worth, Texas.

[Project Review]  Regular class Competition:  2 hp, O.S..61 FX  Planform Area limit: 1000 in 2  Maximum take off distance: 200 ft  Maximum landing distance: 400 ft  Maximum total weight: 55 lb

[Project Review]  High Wing Monoplane:  Least amount of drag  Easiest for wing prototyping  Ease of construction  Landing Gear:  Tricycle  Tail:  High T-tail

[Project Review]  Airfoil type:  Eppler 423: High lift coefficient Ease of construction  NACA 0009: Adequately avoids the turbulent airflows induced by the main wings.

[Last Semester’s Conclusions]  Fuselage:  Cylindrical shape: Least drag  Wings:  Calculations made for straight rectangular wings.  Calculations were made for slotted flaps and ailerons

[Construction Challenges]  Structural  Composite support  Tapering Wing  Multiple rib stencils  Dihedral Wing  Aluminum blocks  Mono-coating  Dimensioning  Gluing  Pinning  Clamping  Mounting  Rubber banding Wing

[Construction Challenges]  Cylindrical Design  New design Hexagonal  Structural support  Composite tubing  Framing  Plywood  Balsa/Basswood  Mono-coating  Boom  Composite tubing Fuselage

[Construction Challenges]  Structural support  Balsa ribbing  Composite tubing  Foil  Rib stencils  Mono-coating T-Tail

[Construction Challenges]  Mounting  Hexagonal fuselage  Construction  Will be purchased Landing Gear

[Calculations] Last Semester’s Model Where s is the takeoff distance, a mean is the mean acceleration, V TO is the takeoff velocity.

[Calculations] This Semester’s Model Where, s is the takeoff distance, a is now, V is the velocity from 0 to the takeoff velocity. Continued…

[EES Influence] Airplane Dimensions Takeoff Distance Maximum Payload Takeoff velocity Cruising velocity EES EES allows the group to adjust the dimensions of the airplane, and to see what effect that adjustment has on performance.
