Venturi A3 is conducting tethered hover Flyt-Test to determine Max Performance. During these tests the aircraft is attached to the ground and throttle is increased to full power. The tension in the tether is measured along with the Venturi’s weight, battery discharge power and rotor RPM. These data are then used to calculate Thrust Loading (i.e. Thrust per Watt) and Figure of Merit, which assesses power efficiency. Results will inform current design choices and scaling for larger aircraft.
