1 Purdue UniversityAAE 451 Senior Design Team 11 System Definition Review Miguel AlanisAaron Mayne Tim BlockJason Olmstead Becca DaleAdeel Soyfoo Joseph FallonSarah Weise

2 Purdue University AAE 451 Senior Design Team 1 2 Review of Market Air charters, governments (surveying, mail), medical transport, or supplies delivery companies Operates in rural, developing area’s of the world such as Australia, South America, or even rural parts of Canada

3 Purdue University AAE 451 Senior Design Team 1 3 Design Requirements Passengers: 12 (including crew) Cruise Speed: 160 kts Takeoff distance: 2000 ft Range: 1200 nm  One-way full load Weight: approx. 12,000 lbs Cost: < $2.5 million Alternate Fuel Source: Fischer-Tropes Kerosene and Bio - Kerosene

4 Purdue University AAE 451 Senior Design Team 1 4 Trade Studies Largest Tradeoffs are Payload (passengers) or Range Payload and/or Range affect GTOW the most Solid Lines are for Round trip range; Dotted Lines for One Way Range.

5 Purdue University AAE 451 Senior Design Team 1 5 Trade Studies For the desired payload and range, there are only certain speeds the plane can travel Solid Lines are for Round trip range; Dotted Lines for One Way Range.
