General Aviation Market Review Product 4 Seat Single Engine Piston Aircraft for Hobbyists, Training Fleets, and Fixed Base Operators Powered by an Alternate Fuel Customer Needs 100LL Replacement Current staple fuel for GA piston engines Production uncertain after 2015 Provides opportunity to be first to market Petroleum fuel alternative for post peak oil 13 May 2019 AAE 451 Team V

Current Design Requirements ≤ 1500 ft takeoff distance to clear a 50 ft obstacle 600 lb payload with max fuel 150 kts max cruise speed 600 nm range ≥ 48”x46” cabin height x width Estimated GTOW of 2780 lbs Estimated base price of ~$316,000 ($2006) 13 May 2019 AAE 451 Team V

Trade Studies All trade studies were done assuming by varying one of the following and keeping the remainder at the base value shown Range (600nmi) Cruise Speed (150 kts) L/D (12) Payload weight (450 lbs, +150 for pilot) Prop efficiency (0.9) bhpSFC (0.42) Empty weight fraction was based on a nonlinear regression curve fit of a database of similar aircraft Fuel fraction was calculated from a series of weight fractions for our design mission 13 May 2019 AAE 451 Team V
