The ducted fan design variables are investigated to identify the main trade-offs and favorable designs for the target aircraft mission, with special attention to noise. The results show that the performance of fixed pitch fans benefits strongly from hybridization. Ducted fans can also operate ...
motor and 40A ESC provide the power needed for dynamic maneuvers. The 64mm 11-blade ducted fan system delivers a smooth and stable flight, making it an ideal choice for outdoor flying. **Ready-to-Fly Convenience** The PNP (Plug-and-Play) setup of the FMS 64mm Rafale V2 means that ...
New! Hero Eagle 100 Version 2 Fiberglass Electric Ducted Fan (EDF) Twin-Engine Radio Controlled Aircraft ARF Kit 81A888-Cess550-DF-100
Results show that for a degree of hybridization of 0.3, the environmental impact of the hybrid-electric configuration increased by [Math Processing Error]15.1%, while the operating costs increased by [Math Processing Error]41.0% compared to a conventional reference aircraft. For a future scenario, ...
How are electric aircraft charged? This is also tricky: electric aircraft cannotchargetheir batteries as easily as anelectric car. Cars simply go to acharging stationand, depending on the model, remain there for at least an hour. However, with airplanes downtime is unprofitable. The two-seater...
This study is concerned with reducing the tonal noise emitted by electric ducted fans which serve as the propulsion system for a variety of unmanned aerial vehicles (UAVs). The underlying concept is utilizing the shroud pressure fluctuation caused by the rotating blades to drive the over-the-rotor...
In the 1980s, General Electric believed that the key to increasing engine efficiency was to explore novel technologies, like propfan engines. To research propfans, or unducted fans as they are properly called, NASA provided the manufacturer with a massive grant that eventually led to the product...
What the authors appear to be suggesting, though, is the general variety of powerplant being proposed for hybrid-electric regional aircraft: ducted-fan engines driven electrically, with a combination of battery power and an enlarged APU to provide takeoff power and sustained cruise/recharge respective...
