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 ...
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...
Aircraft whose primary form of thrust is derived from a piston engine, rotary engine or turboshaft driving a ducted fan. Subcategories This category has the following 2 subcategories, out of 2 total.
Some electric-powered ducted fan airplanes can reach speeds of more than 320km/h (200mph). Most cooling fans used in computers contain a duct integrated into the fan assembly; the duct is also used for mechanically mounting the fan to other components. The Martin Jetpack personal aircraft with ducted fans

By May 2018 almost 100 electric aircraft were known to be under development. [5] This was up from 70 the previous year and included 60% from startups, 32% from aerospace incumbents, half of them major OEMs and 8% from academic, government organizations and non-aerospace companies, mainly from Europe (45%) and the U.S. (40%).

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 the 1960s, Hanno Fischer, Technical Director of Rhein-Flugzeugbau (RFB), developed an interest in aircraft powered by ducted fans integrated into the aircraft structure, flying two modified gliders as testbeds, a VFW-Fokker FK-3 fitted with an eight-bladed ducted fan in the rear fuselage, which flew as the Sirius I in 1969, and a Caproni Vizzola Calif A-21, which flew as the Sirius II on 16 ...
