"Next Generation Nozzle Guide Vanes"
Nozzle guide vanes (NGV) play a critical role in the thermodynamic efficiency, aerodynamic performance, and cost of ownership of gas-turbine engines. The objective of the VANCAST project is to develop the next generation of Ni-based superalloy nozzle guide vane design and manufacturing capability for low pressure turbines of advanced aircraft engines. The industrial benefits for the aviation industry of new NGV designs include reduced emissions, and improved fuel efficiency, reduced weight, and lower operating costs.
The new design and manufacturing capabilities will be established by building an improved modeling capability to simulate mold filling, solidification, residual stress and microstructure evolution during equiaxed casting processes. Critical DOE casting trials will be used to validate the model and enhance the manufacturing capability. These NGV designs and casting technologies will be evaluated using a combination of optimization studies using the enhanced software code developed in the present program, and the casting trials and analyses that will be performed.
IMDEA Materials Institute besides being in charge of the scientific/technical coordination of the project will establish the relationship between solidification history and microstructure, critical for the appropriate simulation of the casting process. This task will be carried out using the Gleeble 3800 system, which is the state-of-the-art technology to study the microstructural development of metallic alloys upon solidification.
