Development of Scaled Airframe for UAM | Korea Aerospace University

Objective

Design, make, fly, and control a scaled airframe for UAM eVTOL

UAM full scale scenario

Preliminary Design

Rotor Tilting System Development

Variable Pitch Motor-propeller System Development

Developed 3-blade collective pitch motor-propeller system with maximum 68 N thrust.

developing variable pitch mechanism using robot servo and swash

Developed logger and wind blower to test and collect data of the propulsion system under wind inflow condition. The logger recoerds 11 parameters: thrust, torque, vibration, motor RPM, motor temperature, voltage, current, airspeed(behind the thruster), pitch servo position(PWM), pitch servo load, and noise. And the wind blower can make wind upto 12 m/s for 30 minutes.

thrust test setting with data logger and wind blower

The test result is on analysis.

test result of thrust about RPM according to various propeller pitches and inflow speed

Prototype development

Prototype subscale aircraft is on building with carbon composite.
