Description & Application

The paper traces the evolution of the Tay engine, launched in response to the requirement for an engine suitable for powering a FAR Part 36 Stage 3 noise compliant aircraft in the 70–100 seat range. The engine, which is derived from the Spey (RB183) MK 555 installed in the Fokker F28 aircraft, incorporates several latest technology features a number of which are already in service in large turbofan engines. Modularity and maintainability are key areas which have been addressed in the design of the engine; these are discussed in regard to operation in service.

Results, Conclusions & General Observations

The eight engine/two year development programme from first engine run to Type Approval by the United Kingdom Civil Aviation Authority is reviewed with detail description of some of the more important and interesting tests. Certification by the US Federal Aviation Administration was subsequently achieved under reciprocal cross-validation procedures. Flight certification of the two lead aircraft applications is now complete.

With completion of type certification of the baseline engine and production deliveries now underway, attention is being turned to growth derivative versions of the engine: an uprated version, due to come on stream late 1988 in an increased weight version of the Fokker 100 has now commenced its certification programme — and further growth capabilities are being explored.
