The SAAF Forum

Our company currently installing RR Viper-540 "Atlas" engine on L-29 aircraft in Russia. Our supplier from USA told
us, that this engine had operated in SAAF before.

We met a real shortage of information on our way, due the manuals we have are from Viper-535 and not enough helpful.

Can you help us with such questions as:

1. Where is high fuel pressure port positioned on the engine?
2. How the bleeding valve operates? (it has electric connector and supposly not automatic as 535 one)

Actually we're looking for any Party who has an experience to operate this engine and can share or sell information about Viper-540
with/to us.

Thank you in advance.
