The RC aircraft enthusiast [RCMakerLab] examined on YouTube whether the ducted fans (EDF) in mini air blowers, used as alternatives to compressors and compressed-air canisters, could be used in model aircraft. These devices are used for dust cleaning. The simple construction of the disassembled device, the ESC being connected to the EDF, and the presence of only an on-off switch with speed control on the outside make integration easier. In a custom setup, the fan was found to produce 110 grams of thrust at 16.5 A; this could help it carry its battery. An aircraft will probably require two motors. Weight could be reduced by replacing the ESC; EDFs from discarded or faulty devices could be tested. This solution was said to be more promising than an aircraft powered by an electric leaf blower.
Why it matters
This approach shows that the thrust components that can be used in model aircraft do not necessarily have to come only from specially manufactured motors or compressors. In particular, repurposing discarded or faulty mini air blowers could provide access to a fan unit with its electronic connections ready; however, its practical value depends on whether the fan can carry the battery and fuselage along with its own weight. Since the thrust provided by a single motor is limited, the design may require two fans and a corresponding power system, taking the project beyond a simple component replacement. The key open question is whether the measured thrust will provide sufficient balance and lifting capacity in an actual flight configuration.
