Defense Update

has been working on a parallel program with DARPA, seeking to develop an advanced electrically powered lift fan that could be used with VTOL aircraft . Partnered with ThinGap and Trust Automation, the team’s unique approach utilizes a DC brushless ring motor, high switching rate controller, and ducted fan to deliver the required lift. The low disk loading compared to turbojets and turbofans minimizes the amount of debris kicked up during operation. The Defense Advanced Research Projects Agency (DARPA) funded contract has produced a 32-inch diameter ducted fan powered by a 70kW electric motor capable of producing over 430 pounds of thrust. The advanced aerostructure design by Aurora Flight Sciences coupled with a unique composite ring motor from ThinGap performed several thrust tests characterizing the continuous operation as well as peak performance of the integrated syste...
