In aeronautics, a ducted fan is a thrust-generating mechanical fan or propeller mounted within a cylindrical duct or shroud. Other terms include ducted propeller or shrouded propeller . [ 1 ] When used in vertical takeoff and landing ( VTOL ) applications it is also known as a shrouded rotor .
The first flight of the E-Fan 2.0 was originally planned for 2017 and the E-Fan 4.0 for 2019. [1] A ducted fan on the E-Fan. The E-fan is of all-composite construction and is propelled by two ducted, variable-pitch fans spun by two electric motors totaling 60 kW of power. Ducting increases thrust while reducing noise, and having the fans ...
The LightningStrike is a tilting-wing design powered by one Rolls-Royce AE1107C turboshaft engine, the same type used on the V-22 Osprey, that generates electric power via three Honeywell generators to run 24 distributed ducted fans, three each in the forward canards and 18 across the main wing.
The air vehicle is electrically powered, and was initially propelled by four ducted fan rotors, two larger fans on the top and underneath providing thrust and two smaller fans at the wingtips for steering. This propulsion system enables it to achieve a top speed of 80 m/s (288 km/h; 155 knots).
The J85 and lift-fan combination was a precursor to developments which led to the first GE high BPR engine, the TF-39. [4] The lift fans were driven by turbine blades mounted around the periphery of the fan, with mass flow 13 times greater than the gas generators mass flow and increased thrust 3 times over that available using a propelling nozzle.
In 2021, Urban eVTOL announced the Leo, a 3-seat, 250 mph (400 km/h), 300 mi (480 km) vehicle. It hosts 16 40-cm diameter, 10-kw ducted fans for vertical lift, and 6 28 cm diameter, turbine-bladed rear engines for horizontal thrust. The wing is a double box-wing design.
