2. SAE Aero East 2017 MAE 435 Mid-Term Progress Presentation

3. Sponsored by the Society of Automotive Engineers
Aero East Competition
Sponsored by the Society of Automotive Engineers
Objective is to fly “revenue” generating passengers and their luggage
Must make accurate predictions of passenger capacity and weight
Scoring affected by empty seats and incorrect ratio of passengers to luggage weight
Most design work completed by outgoing group
Concentrated on manufacturing techniques and actual construction of the airframe

4. Wing Construction Bulk of the wing design finished by previous group
Basic wing structure completed by previous group
Method of wing section joining had to be designed

5. Wing Construction Wing Joiner 3 piece wing for transportation
Outboard sections joined at spars
Joiner design tested and final design agreed upon

7. Wing joined for the first time

8. Wing Construction Leading edge D tubes formed and installed
Aileron servo mounts designed and installed
Ailerons designed and constructed
Spoiler servo mounts designed and installed

9. Installing Leading edge D tube sheeting

10. Wing leading edge D-Tube

11. Wing Construction Wings Covered Wing Control surfaces installed
Winglets manufactured and installed
Wing-Fuselage interface will be constructed after fuselage construction is complete
Landing gear mounts and luggage bay incorporated in Wing-Fuselage interface

12. Covering Wings and Control Surfaces

14. Empennage
Constructed using plywood jigs manufactured with department Shop-Bot
Elevator and Rudder control surfaces constructed and installed
Servo mounts and servos installed
Linkages completed
Construction 100% complete

16. Fuselage Construction
Semi-Monocoque design constructed using frames and longerons/stringers
Construction of frames intended to be balsa laminated in a shaped jig
Planning and design of jigs proceeded to an advanced state
Ultimately rejected in favor of laser cut plywood frames

17. Example Fuselage frame construction Jig

18. Overview of Fuselage without Sheeting

19. Fuselage Construction
Jigs were used to construct the fuselage
Cut using Department Shop bot from plywood
Jig ensured all frames were vertical and located at the correct fuselage station
Kept keel structures aligned and oriented correctly

23. Other Construction tasks
Landing gear
Stress analysis completed.
Gear purchased and will be modified by ODU Machine Shop
Luggage Bay
Material received and in Machine Shop for manufacture of parts and payload plates
Transportation cages and trailer modifications
All drawings and design work completed
Materials received and construction will begin in two weeks

24. Current Roadblocks
As we assemble the aircraft, some mis-alignment of components has been encountered
Some detail work has not been modeled yet

25. Tasks remaining Finish construction
Finish and submit SAE competition report
Test flights
Refine design as necessary
Compete and win!
