An event that challenges engineering students in the United States and internationally through the design, build, and test of an aircraft Three Classes: Regular The standard class we are interested in Advanced Extra challenge for experienced teams Micro A new class focusing on small scale craft The goal is to build an aircraft to carry a greater weight than others while following a set of restrictions and generating accurate engineering documentation
RIT Aero Design Club has been absent from the competition since 2008 Prior to 2008, RIT had been inconsistent in participating in the competition annually Lacking Experienced veterans to lead/guide the club Aeronautical engineering experience/knowledge Full commitment as students are on co-op for parts of the year Funding
Deliverables A functional finished aircraft designed and built to SAE Aero standards Comprehensive documentation of design, build, and testing methods and processes Jumpstart the Aero Club Build competence through sharing experience from the present Senior Design project Desired State: Aero Design club is able to compete in the SAE Aero Competition annually and be competitive

Importance Key: 3=must have, 2=nice to have, 1=preference only
Importance Key: 9 = Critical 3 = Moderate 1 = Insignificant *Note: All engineering requirements derived from SAE Aero rules are deemed critical as failing to meet the target values will result in penalization or disqualification.

Make sure rudder is adequately sized and has sufficient angular deflection capability to remove any sideslip angle, using theoretical calculations and applying a factor of safety. 1. Research previous winning aircrafts and the payloads that they were able to carry. 2. Design the aircraft to carry more than that payload, and include a factor of safety in the lifting capability. 3.
