Elmec Engineering Ltd. is proud to announce that the first set of it's Directionally Solidified (DS) Cast High Pressure Turbine (HPT) Blades has been successfully installed in our Rolls Royce Avon mark 1533 gas turbine. The blade set was cast using CM 186LC, a superalloy formulated by the Cannon-Muskegon corporation and introduced into the Aerospace market in 1996. This alloy received extensive testing by Rolls Royce during it's development. CM 186LC is unique in that it can be cast in both Single Crystal and Directionally Solidified metallurgical structure.
DS Air Cooled HPT Blade Set for RR Avon Engines The blade set was cast to fit all marks of Avon engines. Normally the blades for 1533 Avons are cast solid. Blades for the upgraded models 1534 and 1535 are air cooled. Corresponding modifications were made to the engine to allow the 1533 to peak at 1534 EGT. It has been designated a "Peakable 1533". |

The engine build and modifications were performed by S&S Turbine Services in Fort St John, BC, Canada. Their facilities include a Test Cell to fire clients engines after overhauls. It is a good venue to test the performance of engines receiving aftermarket parts and modifications. The above engine is only one of many which S&S Turbine services have modified. Prior to the test of the Avon, a GE LM1500 with a set of 1st stage Elmec DS aftermarket blades was run. This engine was also fitted with experimental low NOx combustors developed by S&S Turbines. It received 14 starts at full power, and is scheduled to go into pipeline service for 2000 hours for emissions reduction testing and evaluation. |

The peakable Avon mark 1533, serial # 37116, was purchased with only 47 hours of run time after a RR overhaul. It was inspected by RR prior to Elmec's acquisition. The full inspection report and all logs and records accompany the engine. This engine is now being offered for sale as a core to any interested parties. The price is $750,000 USD. |

The tests performed in late July and early August, 2001 have included 5 starts to 7600 RPM. A video of the first 2 is available. The engine will be reinstalled in the test cell if any interested buyers wish to witness it's performance prior to purchase. |
