Non turbine APU

[pitciblackscotland]

I came across this APU and thought what the hell, buy it buy it I am a fan of rotary engines and you don't see many of these up for sale. This one is a sachs wankel engine with a 28 volt generator and gearbox. The chap i got this from said these APUs are off a army helicopter,that's about all i know about them at the moment will do some more research.

Cheers,
Mark.

that's an interesting one!


A friend of mine has a couple of those Sachs engines, one was from a snowmobile and the other was set up for an ultralite aircraft I think.

Yep,
They were also use in lawn mowers, chain saws,boats,gen sets,water pumps,motorcycles and a single rotary engine made for some small cars back in the mid 1950s.

Well i finally got the engine up and running all good. Very smooth running of this engine not like a piston engine does which would be shaking around.

Hi John,
Yeah a cute engine LOL i usually like big and heavy duty stuff No dramas starting the engine as the seller did a test run before i purchase it. This is a 4 stroke engine and it needs a 2 stroke fuel mix to lubricate the apex seals and bearings.

Cheers,
Mark.
