The GUIde 4 Consortium: Working Together for Better Gas Turbines

Great leaps forward in turbomachinery and turbine design have played a pivotal role in moving civilization forward.  Steam engines sparked the Industrial Revolution, driving machines to produce textiles, mill grains, and transport goods and people long distances.  Steam turbines made dramatic changes in ship engine design, and are commonly used today in power generators.  The turn of the 20th century also introduced gas turbines capable of producing excess power.  In the modern age, thermal turbines are essential components for electricity and transportation throughout the world.  In aeromechanics, the use of powerful gas turbine jet engines have, literally, given rise to high-speed commercial passenger and military aircraft, and air travel today is much faster and easier than ever before. 

Jet engine design is not without challenges, however.  Excessive vibration of turbomachinery bladed disks can lead them to severely fail in high cycle fatigue (HCF), potentially resulting in complete blade separation and loss of power, significant cost, and loss of life.  

To address these challenges of blade efficiency and reliability, the GUIde Consortium was formed. The acronym “GUIde” stands for Government Agencies, Universities, and Industry working together on a common goal. Through cooperation, the organizations within the Consortium develop an enhanced view of how to achieve their objective. Consequently, the Consortium serves as “guides” for one another in solving challenges in controlling the vibration of bladed disks.
