Dual Propeller Thrust Test Rig

Written By John Hughes

This dual propeller thrust test rig was developed to investigate the effects of overlapping propellers on propulsion performance. It was successfully used to characterize the effect of axial and lateral propeller overlap on propulsion efficiency. This information was then used in the optimization of the propulsion system and overall layout of Kite, a high performance VTOL UAV.

Key Features:

  • Supports dual motor setup with rapid lateral and axial position adjustment capability

  • Measures current, voltage, thrust, RPM and temperature

  • Dual channel power monitoring

  • Computer data logging in addition to easy to use built-in controls

Project Details:

  • Fast turnaround project completed in two weeks

  • Designed in SolidWorks using frame generator tools

  • Fabrication and electrical work was carried out myself using in-house capabilities

  • Coded in Arduino

Complete setup, shown configured with 50% lateral propeller overlap

Electrical layout, makes use of off the shelf modules for rapid development
