Competition Member Requirements l SAE – – l All team members to be members of SAE All team members need to be undergraduate/graduated 7 months prior to competition AIAA – – All team members to be members of AIAA Team must consist of at least 1/3 undergraduates (Freshman, Sophomore, or Junior)

Mission Profile l SAE Regular, Open, Micro – – 5 min takeoff time limit (multiple attempts allowed) Someone is allowed to hold the aircraft during engine rev-up Takeoff Zone: 200 ft (100 ft for Micro class) Flight Path: l l l – – – 360° Turn overall travel past the takeoff zone 180° turn travel past the approach zone 180° turn Landing Zone: 400 ft (200 ft for Micro class) Aircraft remains intact (except propeller) Repairs allowable (except alteration of design)

Mission Profile (Continued) l AIAA – Takeoff l l – – Takeoff Zone: 100 ft Flight Path l l l – – – Maximum flight attempts: 5 2 min prep time for each flight attempt 360° turn overall travel 500 ft past starting line 180° turn Landing Zone: 200 ft (not exactly sure) Aircraft remains intact (except propeller) Repairs allowable (except alteration of design)

Important Aircraft Requirements l SAE Regular – – – – Wingspan: 94. 488 in Max Gross Weight: 55 lbs Payload Volume: (3 x 5 x 16) in block must be able to fit Payload: Consist of plates, can’t move Engine: Single, unmodified O. S. . 61 FX w/ E-4010 Muffler 1 to 1 propeller to engine RPM ratio Fuel: 10% Nitro Methane Fuel (supplied) Propeller: Metal not allowed

Important Aircraft Requirements (Continued) l SAE Open – – – Wingspan: Unlimited Max Gross Weight: 55 lbs Payload Volume: Unresticted Payload: Consist of plates, can’t move Engine l l l – – – Internal, Combustion Reciprocating Engine Max Displacement: . 91 in Not restricted in total engine displacement, number of engines, make or model Allowed to differ propeller to engine RPM ratio Fuel: Can use own fuel (restrictions) Propeller: Metal not allowed

Important Aircraft Requirements (Continued) l SAE Micro – – Wingspan: Unlimited Purpose: Carry highest payload with lowest empty weight Payload: Consist of plates, can’t move Engine: l l – – – Internal, Combustion Reciprocating Engine or Electric Motor Propulsion Not restricted in number of engines 1 to 1 propeller to engine RPM ratio Fuel: Can use own fuel (restrictions) Propeller: Metal not allowed

Important Aircraft Requirements (Continued) l AIAA – – – Wingspan: Unlimited Max Gross Weight: 55 lbs Payload Volume l l l – Engine l l – Able to carry 96 tennis balls Able to carry two-two liter bottles Able to carry 4 x 24 in not weighing more than 8 lbs Electric Motor Multiple motors allowed Propeller: Commercial

Flight Scoring l SAE Regular – Flight Score=Raw Weight Score + Prediction Bonus l l l SAE Open – Flight Score=Raw Weight Score + Prediction Bonus + Zero Payload Bonus + Stopping Bonus l l l Raw Weight Score=Weight lifted in pounds x 3 Prediction Bonus=20 - (predicted payload – actual payload)2 20 points if mission carried out with no payload 20% of Raw Weight score if aircraft lands within landing zone SAE Micro – – – l Raw Weight Score=Weight lifted in lbs x 4 Prediction Bonus=20 - (predicted payload – actual payload)2 Flight Score=(10 – EW) x PF x 13 EW=Empty Weight in pounds PF=Payload Fraction=Payload Weight/(Empty Weight + Payload Weight Overall Score for any of the above three competitions – Overall Score=Design Report Score + Oral Presentation Score + Flight Score

Flight Scoring (Continued) l AIAA – Cargo Flexibility l – Min RAC l – – Flight Score=150/Rated Aircraft Cost (RAC) Incremental Load l – Flight Score=10 x (# Laps/Loading Time) Flight Score=1. 25 x # Laps Total Flight Score=2 best flight scores of above three are summed Overall Score = Written Report Score * Total Flight Score Rated Aircraft Cost
