Pratt & Whitney Canada is committed to set the standard in replacing hazardous materials and processes by using green materials and by manufacturing engines using green processes.
What is Pratt & Whitney Canada doing to reduce noise levels in engines? Our objective is to reduce cumulative noise levels by 10dB over the next 10 years and we are working with Canadian universities and the National Research Council to develop analytical tools for predicting noise levels generated within combustors and exhaust ducts. This project represents the only R&D effort of its type in Canada.
In design, Pratt & Whitney Canada is optimizing engine cycles for a low-noise signature and our current engine designs meet the most stringent standards.
Pratt & Whitney Canada has already achieved significant reductions in reducing “materials of concern” in our newer engines, such as cadmium.Some results include:
- Elimination of chlorinated solvents for our products
- Elimination of mercury in our parts
- A 90% reduction of parts containing cadmium
- And over 80% reduction of parts containing lead
In our latest PurePower™ PW800 engine, for example, we have eliminated 100% of what we refer to as Level 1 materials of concern, mainly cadmium.
Pratt & Whitney Canada is also conducting research and characterization programs with UTC, suppliers, universities, the NRCC and the École Polytechnique to replace a number of materials of concern in the manufacturing process.
Pratt & Whitney Canada continues to invest in reducing waste products and eliminating toxic products in all our manufacturing facilities. Our record of reducing direct environmental impacts has been exceptional in targeting waste, air emissions, water consumption and energy use.
