Greetings all!
I am searching something that is not existing anymore or almost at least!
The APU of Antonov 24, 26 and 30 is EN 19-300 . . . a YAK turbo jet engine adopted by Antonov to use as the APU.
here is a russian link (
Турбореактивный двигатель (ВСУ) РУ 19-300)
might have to use google translator!
Anyone of you have any experience flying with this or have any documentation?
I just got hold of one (with zero hours but expired calender days) laying in dust and trying to do a dry motor. Simply this is a single spool 9 staged compressor with single stage turbine. And the N shaft is NOT connected to the gear box directly as I can rotate the shaft by hand. Are there are any APUs with any clutch mechanism? if so this is one!, There there are quite a few clarifications I seek before I even do a dry run. Your input is greatly appreciated for this matter!
Thank you all!
