can any one help me out with how ac electrisity is generated and distributed on an aircraft?

Elaina Adolfson: You haven't given enough details for your question. Is it a commercial type jet, or a small single engine prop? in most jets from the DC-7 & larger there's a section high up on the tail that's the turbine generator. The olds style automobile generators were A/C, not DC. Aternators replaced them to give a constant DC output. Even most riding lawn mowers use the generator system since it can be used as the starter as well. Generators take a lot longer to charge a car battery than does the alternator. It costs a lot more to convert the DC into AC, than the other way around. From AC to DC only needs some form of bridge rectifier. Where as DC into AC with an inverter has to create the AC pulse at the given frequency range needed!...Show more

Janeen Perona: that is generated via turbines put in on the engine(s). that is allotted the properly-known way -- with wires. maximum plane electric systems are the two one hundred twenty/208 volt, 4 hundred Hz, 3 Ph! , Y, AC or 28 volt DC.

Judie Kise: AC is produced by a generator which is driven by the exhaust of the turbine engine,if your using a turbine driven aircraft. The AC is sent to the AC buss where it is distributed to other equipment on the plane. The is also a DC buss for equipment requiring DC voltage. Ex Navy aircraft electrician. Some commercial aircraft have a seperate turbine which drives its generator.

Marcelina Schossow: There is only really one working voltage that is Direct Current.Alternating Current is more of a transport technology, mostly all devices convert AC into DC for there operation, there are a few exceptions.AC from DC requires a Inverter
