High bypass ratio turbofan engines are used on nearly all civilian airliners, while military fightersusually make use of the better high-speed performance of a low bypass ratio turbofan with a sm… In aircraft applications, the operating speed of an unshrouded propeller is limited since tip speeds approach the sound barrier at lower speeds than an equivalent ducted fan. This ducted electric lift technology has applications to vertical take-off and landing vehicles, helicopter tail rotors, and aircraft propulsion.This project is sponsored by the DARPA and the Air Force Research Laboratory (AFRL) under contract number FA8650-10-C-7072.Aurora, ThinGap, and Trust Automation electric lift fan thrust testAurora Flight Sciences designs and builds aerospace vehicles for commercial and military applications.

The team’s unique approach utilizes a DC brushless ring motor, high switching rate controller, and ducted fan. endobj stream Aurora is headquartered in Manassas, VA and operates production facilities in Bridgeport, WV and Columbus, MS as well as a Research and Development Center in Cambridge, MA. <> 12 blade high performance 120mm edf ducted fan unit rc edf calculator single rotor drone a thrust vectoring monocopter aday after the hoversurf bike es evtol formula scaled specific thrust calculation methodology for …

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. �x"VVyR�ˡ���E����./>��_���u6����:��k|i�wW��~Ի���C�M�a���h�oW�$�?^^���������Y��7�p�2.YK�I�d��./~�!�jF�d(���I^尛$e��q�./�vy����6�G��v7���gX΋�UE�U�0�x�k�e^Wȋ?�G��T�*#*Ӛ�p��XF'��I��PZ$�-pS����*�C�I���x]�jJ�QA?�޽K�����*�u��\�,N���Y����o�Om������o�]9����l͛2��X�hzԔAH)���t�-��)�S&��1�c�`hDѺ-�h�@ The system performed well and was only outdone by a 54 mm fan…

The most common ducted fan arrangement used in full-sized aircraft is a turbofan engine, where the power to turn the fan is provided by a gas turbine. The team’s unique approach utilizes a DC brushless ring motor, high switching rate controller, and ducted fan. The fan will be dealt with in the next chapter. ���g��r�4�~T�To�^���`�}��"q���ŀ���)yL떾kFH��rOKV-�/Hb�h�߯47�w@X�5 Aurora Flight Sciences along with partners ThinGap and Trust Automation are answering the need for safe, high power density electric lift fans, with specific interest in vertical takeoff and landing (VTOL) air vehicle applications. You can select the fan diameter, the voltage, the thrust range, the blades number or the type of motor. The Case diameter will always be larger than the Hub Diameter. endobj endobj Do not enter a value in mm and the other in inches. Output after Submission button is clicked will appear above. Additional testing was successfully performed using an advanced controller of Trust Automation’s design, which implemented very high switching rates and Field Oriented Control to effectively control the low inductance system.“Aurora has shown excellent leadership and engineering skill alongside their teammates ThinGap and Trust Automation with the design and demonstration of a compact ducted fan powered by a novel electric ring motor,” said Steve Waller, DARPA Program Manager. 3 0 obj <>>> It allows you to choose between the original 11000kv motor and the new 13000kv motor. Assuming you design your fan for high static thrust: for a 6 inch diameter to produce say 300lbs of thrust (lifting man and 100lb machine) you will need a 360hp powerplant. Electric Ducted Lift Fan Completes High Powered Thrust Tests. 1 0 obj To learn more about Aurora please visit our website at www.aurora.aero. 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 system. The fan itself is in this chapter regarded as a black box that simply adds energy to the passing stream.
