Just so that we are all on the same page and that we are all using the same language, you cannot make an "electric turbine". What you want to built, is an "electric-powered propeller". Here what you should know to understand what a turbine does (the info comes from wikipedia):
http://en.wikipedia.org/wiki/Jet_engine" : It is a reaction engine that discharges a fast moving jet of fluid to generate thrust in accordance with Newton's laws of motion.
In some common parlance, the term jet engine loosely refers to an internal combustion duct engine. These typically consist of an engine with a rotary (rotating) air compressor powered by a turbine ("Brayton cycle"), with the leftover power providing thrust via a propelling nozzle.
----> This is what most of us refer to as a "turbine" (the engine itself).
http://en.wikipedia.org/wiki/Ramjet" :
A Ramjet is jet engine that does not have a compressor. The compression is done by vehicle speed (> Mach 3). Like all jet engines, the power comes from the thrust provided by the heated exhaust.
http://en.wikipedia.org/wiki/Turbojet" :
The turbojet is a ramjet with a compressor, such that the compression doesn't rely as much on the vehicle speed (Mach 1 < v < Mach 3). That compressor is driven by a turbine (which take some energy from the heated exhaust) and the vehicle is still propelled by the thrust provided by the heated exhaust.
http://en.wikipedia.org/wiki/Turbofan" :
The turbofan is a turbojet for vehicles with lower speed (< Mach 1.6). It has the same compressor and turbine as the turbojet, but it has an extra turbine that powers a fan. The fan contributes to compress the air for the jet engine but it also bypass some fresh air around the exit nozzle. The power source is still the thrust provided by the heated exhaust.
http://en.wikipedia.org/wiki/Turboprop" :
The turboprop is not a jet engine, it is a propeller (or any other device) powered by a "turbine". In this case, there is still a compressor driven by a turbine, there is also another turbine that drives a propeller (similar to the turbofan) but this last turbine removes
all energy (or as much as it can) from the heated exhaust gas such that there is none left to provide a forward thrust (hence, the reason why it is not a jet engine). The maximum speed of the vehicle must be < Mach 0.75 (see http://en.wikipedia.org/wiki/Propfan" ).
In this case, you can replace the "turbine" by a typical 4-stroke engine or an electric engine if you want. But you still need a propeller or a fan, but not a "turbine".
Commercial air carriers use turbofan as their speed are around Mach 0.8. Fighting jets use turbojet as their speed are supersonic. Ramjet principles are use with airplanes like the Blackbird SR-71 (
http://en.wikipedia.org/wiki/Pratt_&_Whitney_J58#Turbo-ramjet_design").
http://en.wikipedia.org/wiki/Motorjet" :
This is probably closer that what you want to do. An external motor replaces the turbines that drives the compressor (and fan) of a jet engine. In this case you can also use an electric motor to do the job. The question is: In an airplane, is the added fuel consumption for the weight of the electric motor and batteries vs the turbines is less than the fuel saved by the electric motor?
