RU19A-300

A classic Russian engine, electric start and fairly easy to get up and running.

The RU19a-300 is used on an Antonov AN-26 transport aircraft, built in behind the engine nacelles the turbine primarily acted as an APU, but when required it could throttle up and provide additional thrust for heavy lift off’s of steep climbs.

P and Y in Russian is apparently R and U, you learn something every day.

The engine utilises an air bleed system, when the RPM reaches about 86%, (which I need to check) the air band around the compressor section closes to avoid compressor stall, this band is actuated by the solenoid seen in the picture below.

The air band can be seen centre picture below, not that exciting to look at.

I know what two of these solenoids do, no idea about the others, must be aircraft accessory related?

A white sheet was placed over the fuel tank to help keep it cool in temperatures of up to 45 degrees C.

At one point I had three RU19 engines, one was sold and now I have two. The other engine is a M701, this is covered elsewhere on this website.
