Williams Fanjet Family

Product catalog summary

Introduction
The document provides technical specifications and an overview of the Williams International FJ33/FJ44 engine family, highlighting its innovation, technology, and service.

Engine Specifications
The FJ33/FJ44 engines are two-spool turbofan engines featuring two low-pressure turbines and one high-pressure turbine. They are designed for high thermal and propulsive efficiency with minimized noise. The engines are controlled by a dual-channel Full Authority Digital Engine Control (FADEC) system.

Catalog excerpts

The Williams Fanjet Family A Legacy Built on Innovation, Technology and Service The FJ33/FJ44 family began with the introduction of the simple, rugged FJ44-1A. Using elegant engineering solutions and embracing new ideas, Williams created a reliable, easy-to-maintain engine that was inexpensive to own and operate. This two-spool turbofan engine uses two low pressure turbines to drive a fan and intermediate pressure compressor, and one high pressure turbine to drive a centrifugal compressor. More than half of the air flow bypasses the core and is remixed with the airflow in the exhaust which yields high thermal and propulsive efficiency while minimizing noise. Engine control is provided by a dual channel Full Authority Digital Engine Control (FADEC), which reduces F J44 pilot workload by using redundant computers to optimize engine performance at all flight conditions, while monitoring engine parameters to prevent exceedances that could damage the engine. As this engine spurred growth in light jets, the product line expanded to the current four models, improving performance and durability with each new model. More than 5,700 FJ44 engines are in service, and have accumulated over 13 million hours in flight. This FJ33/FJ44 engine family enables airplane makers to grow their airplane families economically due to common installation, operation, and maintenance across models.
