Extended product lifecycle management through social computing technologies

This study will present a method for improving informal information flow during product development process in aerospace industries using social computing tools. In actual engineering information exchange, the knowledge is transmitted informally around the coffee machine or through a formal document in the process. In contrast, the author presents a method for proactive participation of […]

Improvement of the fire resistance of Discontinuous Long Fiber Thermoplastic Composites for gas turbine engine applications

Pratt & Whitney Canada (P&WC) is interested to further investigate the use of novel Polymer Matrix Composites (PMC’s) technologies, in order to improve their products by reducing weight and increasing performances of their engines. Current applications of PMC’s in P&WC’s engine are mostly limited to cold section parts (< 100°C), nonstructural external components, and nacelle […]

Validation and calibration of Squeeze Film Damper Model with Experiment

This research project studies a specific component in the commercial aircraft engine called the squeezed film damper, or SFD. The SFD is applied to reduce the vibration of the engine rotor, which in turn reduces the noise and brings comfort to the passengers. The expected delivery from this project includes an advanced SFD model which […]

Nonlinear Dynamic Analysis of Aero-Engines

Aero-engines are lightweight structures which are assembled of several thin walled cylindrical components (casings). Casings are joined by bolted flanges, and must withstand high forces. To accurately predict the response of casings assembly, the non-linear behavior of the casing joints must be considered. Currently, aero-engine manufacturers (i.e PWC) are facing serious limitations in matching the […]

Human Errors Analysis in an Aircraft Engine Assembly Center

Human operators show significant variability in performance when operating in complex manufacturing systems that are usually referred to human errors. Such errors are identified as the failure to perform an action within the safe operating limit and often lead to product quality defects. Approximately 50%-80% of the incidents and accidents in safety-critical systems have been […]

Polymer Composites and Thermoformed Thermoplastics for Engine Fire Zones

This project is intended to develop the technology to form high performance plastics reinforced with carbon fibre (polymer composites) in order to produce lighter parts to replace conventional metallic parts. As the parts may be exposed to fire during use, a comparison between different material systems under fire exposure is also required to have a […]

Pratt & Whitney Canada Pre-Detailed Design System for Turbines

The aero-engine design process is highly iterative, multidisciplinary and complex in nature. The success of an engine depends on a carefully balanced design that best exploits the interactions between numerous traditional engineering disciplines such as aerodynamics and structures as well as lifecycle analysis of cost, manufacturability, serviceability and supportability. Pratt & Whitney Canada (P&WC) is […]
