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. High bypass ratio turbofan engines are used on nearly all civilian airliners , while military fighters usually make use of the better high-speed performance of a low bypass ratio turbofan with a ...
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 ...
The RFB Fantrainer (or Fan Trainer) is a two-seat flight training aircraft which uses a mid-mounted ducted fan propulsion system. Developed and manufactured by German aircraft company Rhein-Flugzeugbau GmbH (RFB), it has been used by the Royal Thai Air Force. Development of the Fantrainer commenced during the 1970s.
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 ...
The remaining components added to the plane are virtually the same as can be found in any other R.C. aircraft of similar size. This concept of building simple radio controlled airplanes using cheap materials without the time-consuming and painstaking process of working with balsa wood and iron-on plastic coating was popularized by a web site ...
This fan-in-tube design has been adopted successfully for electric-powered jets while glow engine powered ducted-fan aircraft are now rare. Small jet turbine engines are now used in hobbyist models that resemble simplified versions of the turbojet engines found on commercial aircraft, but are not scaled-down as Reynolds numbers come into play.
Each power unit comprises a Wankel rotary engine directly driving a ducted fan. [7] [8] The housing is lined with Kevlar to contain the fan blades in the event of failure. [7] The Skycar has four such nacelles, each with two Rotapower engines mounted in tandem. All eight engines operate independently under computer control and, as demonstrated ...
