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: *Note: All engineering requirements derived from SAE 9 = Critical Aero rules are deemed critical as 3 = Moderate failing to meet the target values 1 = Insignificant will result in penalization or disqualification.
