Mission Statement We will design and build a micro-turbine/generator that can be integrated onto a micro-air-vehicle airframe and power the vehicle’s accessories. The micro-turbine will be a continuation of the previous team’s project with the application of their design to be used for MAV power production. 05002 Micro Turbine III Senior Design
Background • Current battery technology causes the battery to be up to half of the weight of the MAV. • Research into lighter weight power generation methods led to micro-turbine generators. • Third generation RIT Senior Design project 05002 Micro Turbine III Senior Design
Primary Objectives • Produce a constant 5 watts of power • Overall weight of less than 45 grams • Integrated into the MAV airframe • Minimum flight time of 3 minutes Additional Objectives • Drive the propeller of the plane • Increase efficiency of the system 05002 Micro Turbine III Senior Design
