Objective & rULES

     The main objective of the project is to built and design an RC model plane that will be able to lift as much weight as possible with a 1000 square inch wing plantform (as states in the SAE Aerodesign 2007 competition rules) but that is just part of the objective. The actual competition divides it’s self into the flying score, written and oral presentation.

Restrictions of the Flying Score:

Takeoff Zone
Regular Class aircraft must lift from the ground within a takeoff zone measuring 200 feet (61m) in length. Open and Micro Class aircraft must lift from the ground within a takeoff zone measuring 100 feet (30m) in length. Takeoff direction will be determined by the Air Boss, and selected to face into the wind. Aircraft must remain on the runway during the takeoff roll.

Competition Circuit Requirements
The aircraft must successfully complete one 360° circuit of the field. During departure and approach to landing, the pilot must not fly the aircraft in a pattern that will allow the aircraft to enter any of the no-fly zones (See Para. 20.3.4). More than one circuit of the field is allowed. During a flight, each aircraft must fly past the departure end of the takeoff zone, turn the aircraft through approximately 180° of heading, and fly past the approach end of the takeoff zone prior to landing.

Payload Bay Limit(s)
Regular Class aircraft must be capable of carrying and fully enclosing a rectangular block measuring 4 inches by 4 inches by 16 inches. During technical
inspection, compliance with this rule must be tested by inserting a block with these dimensions into the aircraft. This block must be easily inserted and
removed without application of excess force during insertion or extraction, and the aircraft must be structurally airworthy with the block installed. Aircraft not
capable of carrying and fully enclosing the defined cargo block will be disqualified from the competition.

Landing
Landing is defined as occurring from initial touchdown to the point at which the aircraft stops moving. Initial touchdown is defined as the point at which any part of the aircraft

In order to participate in the flight portion of the competition, each team is required to have submitted a Design Report and delivered an Oral Presentation, both for score, in thecompetition.

Regular Class Flight Score
Regular Class aircraft will receive a flight score based upon the raw weight lifted and the team’s prediction of the aircraft’s maximum lifting capacity.
Flight Score = Raw Weight Score + Prediction Bonus + Empty Payload Bonus

 Raw Weight Score
The raw weight score will be determined by multiplying the weight lifted in pounds by 4. Lifting 25 pounds will result in a raw weight score of 100 points.
Raw Weight Score = Weight Lifted in pounds × 4

Payload Prediction Bonus
The prediction bonus will be determined according to the following formula:
Prediction Bonus = 20 – (predicted payload – actual payload)2
If the above number is positive, the resulting number will be applied as the prediction bonus. If the above number is negative, no bonus will be applied.

Empty Payload Bonus
An Empty Payload Bonus of 10 points will be available during Flight Round 1 Only.

DESIGN AND ORAL REPORTS
The Design Report is the primary means in which a team is to convey to the judges how they arrived at their conclusion, that the aircraft they are entering in the competition is the aircraft most suited to perform the intended mission. The Design Report should explain the team’s thought processes and engineering philosophy that drove them to their conclusions. Further, it should detail the methods, procedures, and where applicable, the calculations used to arrive at the presented solution. Some topics that are important to cover are: selection of the overall vehicle configuration, wing plan form design including airfoil selection, drag analysis including three dimensional drag effects, aircraft stability and control, power plant performance including both static and dynamic thrust, and performance prediction. Other topics as appropriate may be included. For more information regarding performance prediction, a white paper by Leland Nicolai is available on the Aero Design website. The Design Report consists of the report itself, the plans, and a payload prediction graph. The Statement of Compliance needs to be included as page 2 of the Design Report. The Design Report must be scored with the following maximum number of points available for each section:

Report 40 Points
Plans 5 Points
Prediction Graph 5 Points
Total Design Score 50 Points

Total Competition Scoring
The overall competition score will be the sum of the individual components:
Overall Score = Design Report Score + Oral Presentation Score + Flight Score
