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 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 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 180° Turn from Takeoff RUNWAY Approach End and Takeoff Zone Departure End = 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 • 1st Violation – Invalid flight attempt (no points) • 2nd 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
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 2008 • SAE will not be holding a 2009 competition • Rules can be found here • Dr. Oh wants students to be working on this during the spring and summer terms of 2007 (ideal testing conditions)
