Mission statement

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.

Background

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

Primary objectives

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
