SAE Aero Design West 2008 Information Session

What is the SAE competition? Who - Undergrad and Grad Students (SAE Members) Competition Components - Design Report, Oral Presentation, Flight Classes of Competition - Regular, Open, Micro

What is the SAE competition? Pilots - - Current members of the Academy of Model Aeronautics or the national model aircraft club Design and Fabrication - - Designed and built by the SAE student members (without direct involvement from professional engineers, radio control model experts, pilots, machinists, or related professionals)

What is the SAE competition? Original Design - - Original design whose configuration is conceived by the student team members - Use of major components such as wings, fuselage, or empennage of existing model aircraft kits is prohibited

Deadlines For the 2007 Competition (which has passed) - Registration form and fees: Late December - Design Reports, Plans, and Payload Prediction Graph: Late February

Faculty Advisor Each team is expected to have a Faculty Advisor appointed by the university not Faculty Advisors may not design, build or repair any part of the plane

Mission Requirements Takeoff - Point when main wheels leave ground -Regular Class: 200 ft Zone -Open Class: 100 ft Zone Time Limit - Five (5) minutes to complete successful takeoff The aircraft must remain intact during takeoff!!

Competition Circuit Requirements At least One At least One 360° circuit of the field - Each aircraft must fly past departure end of field - Turn aircraft through 180° of heading - Fly past approach end of takeoff zone prior to landing

Competition Circuit Requirements RUNWAY Departure EndApproach End and Takeoff Zone 180° Turn from Takeoff = 360° Circuit of Field

Mission Requirements Landing - - Touchdown to the point the aircraft stops moving -Regular Class: 400 ft Zone* -Open Class: 200 ft Zone* - Aircraft must remain on the runaway between landing limits to be considered successful landing. * Rolling-out beyond the landing zone is allowed, provided the aircraft touches- down within the landing zone.

Mission Requirements After Landing - Aircraft must takeoff and land intact to receive points for the flight attempt, with the exception of broken propellers No Fly Zones - 1 st Violation – Invalid flight attempt (no points) - 2 nd Violation – Disqualification from event

Mission Requirements Repairs and Alterations - - Original design of aircraft presented in written and oral reports must be maintained during competition - - Alterations may only be made with the permission of the judges but will result in penalty points

Design Objective Regular Class - - Design aircraft that can lift as much weight as possible given dual design constraints of power and wing span limits - - Accurately predicting lifting capacity will result in bonus points - - Max aircraft weight of 55 lbs

Design Objective Regular Class Flight Score = Raw Weight Score + Prediction Bonus + Empty Payload Bonus Raw Weight Score = Weight Lifted in pounds × 4 Prediction Bonus = 20 – (predicted payload – actual payload) 2

Design Objective Open Class - - Design aircraft that can lift as much weight as possible given max aircraft weight limit of 55 lbs. - - No wing span limit

Design Objective Open Class Flight Score = Raw Weight Score + Prediction Bonus + Zero Payload Bonus + Stopping Bonus (must be in landing zone) Raw Weight Score = Weight Lifted in pounds x 3 Prediction Bonus = 20 – (predicted payload – actual payload) 2 *** Open Class aircraft may earn a flat 20-point bonus by performing a flight with zero payload. This bonus will be available during Flight Round 1 only.

Design Objective Micro Class - - The objective of Micro Class is to design an aircraft that can carry the highest payload fraction possible while simultaneously pursuing the lowest empty weight possible. - - No wing span limit

Design Objective Micro Class Flight Score = (10 – EW) x PF x 13 EW = Empty Weight PF = Payload Fraction PW = Payload Weight PF = PW / (EW + PW) *** No prediction points are available for micro class

Design Report Purpose - - To convey to judges how you came to conclusion - - Display the aircraft you built is most suited for the competition Guideline for report Guideline for report

Design Report Contents - Project report (max 30 pages) - Aircraft plans - Fifteen-minute technical presentation - Payload prediction graphs

Final Words - Aero Design West will be in spring of SAE will not be holding a 2009 competition - Rules can be found here here - Dr. Oh wants students to be working on this during the spring and summer terms of 2007 (ideal testing conditions)
