Spey Gas Turbine testing

Rolls Royce Spey industrial gas turbine in the S&S outdoor test cell.
After being completely rebuilt, this engine is being tuned for operation of the compressor bleed valves. This engine is rated at 21 thousand Hp, and today we ran it up to about 75% of that.

How does this gas turbine deliver lubrication to its main rotor bearings? Isn't there a term for a non-recovery oil system? I cannot recall what that term is.

[AgentJayZ]

@rickey5353 Like all other jet engines, but some of the oil sumps require a small negative pressure. The engine needs more support from the off-engine equipment than other industrial engines.

The term is "total loss', I think, and it was popular many years ago with small engines.

@AgentJayZ. I checked out the video, so Solar engines are dedicated ground based engines? They aren't used in any aircraft I know of, and you said they have a built in PT and shaft output.

[AgentJayZ]

@tranceaddict704 Solar are true industrial and marine turbine engines, meaning they were not originally designed to power aircraft and then modified to perform in industrial applications.

Having never been designed to fly, they are much heavier than the aeroderivative industrial engines we see more often in our shop. Some Solars are used to power ships, but they are all heavily built and very reliable engines.

@AgentJayZ. My father works for Williams Transco, which is a natural gas supplier and they have a "solar mars" 15,000hp turbine that they use to run a centrifugal compressor along with several reciprocating engines driving positive displacement compressors. My question is, have you heard of these turbines? He said they have other models too but I didn't get any specifics other than the one he helped install.

[AgentJayZ]

@tranceaddict704 Yes, we work on Solar engines. Have you seen my test video of the Saturn?

The solars have an integral power tubine and a shaft power output. The Speys, Avons, LM1500s and Olympus(es) need to be connected to a separate power turbine, but all these engines, when used in the gas industry, power centrifugal compressors connected to pipelines.

Is there a test load or something like that?

Hi AgentJZ....2 questions....why so much rattle on the back end while spooking down...not enough centrifugal force to keep the blades tight in their slots?and why so many nuts whithout lock wiring?

Sorry my English, I use a translator. I did not think the YouTube I can find videos about our GG. They are my work. We use these motors for gas compression station in Siberia. The complex "Coberra" engine Avon1535 (mod5020). Very good and reliable equipment. And it's very interesting to see him here )))). Thank you.

Great Video as ever! The Adjustment, filmed with the hat-camera felt quite extreme to me, i just thought about 'not to think about, whats going on some inches away inside the engine'.

What kind of camera is the "hat cam"? I seen some footage in the 'racing for the title' video.

P.S.: The VDI is doing a great job in my new car, and looks really great!
