Hi all. Newbie here.

I'm interested in the 18T but really cannot find anything about the electrical system apart from;

"Three power supply systems are used on the Yak 18T. They are: a direct-current of a voltage of 28V, an alternate single-phase current of a voltage of 115V with frequency of 400 Hz and alternate three-phase current of the  voltage of 36V and frequency of 400  Hz. The primary system is a direct-current system with the GSR-3000M generator and the 0NKBN-25UZ  

storage battery. The sources of alternate current are the PO-250A (115V) and the PT-200Ts (36V) converters."

I note there are conversions to remove the generator and install a SK35 alternator.

What equipment used the 115v and 36v?

Thanks. Rod.

We have digitised most of the manuals for the different Yaks, including the 18 T. At the weekend I don't have access to the links, but we will email you the links to these on Monday.



Indeed, there is a list of all the manuals we can offer on our website, so if anyone else would like one please email us. I would emphasise that this is a free service that we offer to owners and operators of these aircraft.

Brilliant service offered by Richard.

I updated my manuals with those provided by Richard.

Thanks Richard for your continued support of these fine aircraft.

The 36 V AC and the 115 V AC systems run to the gyros and some of the radios.
