Focus Tracks

Turbomachines for Clean Power and Propulsion Systems

Recent regulatory changes and market forces require future power and propulsion systems to be “clean”. This emphasis on clean energy has led to increased use of renewables for power generation requiring greater flexibility in operation. For aviation, there is a push to reduce emissions using bio-fuels and electric propulsion concepts that change traditional turbomachinery architecture. Emerging trends and challenges associated with bringing clean energy technologies to fruition will be highlighted at TE19 via keynote, plenary sessions, tutorials, panels, and technical papers. The Gas Turbine Segment and IGTI Leadership Team, as well as TE Committees, strongly believe that having a focus track on Turbomachines for Clean Power and Propulsion during TE19 will benefit the Turbo Expo community.

The TE19 technical paper abstracts submission deadline on various aspects of Turbomachines for Clean Power and Propulsion has passed. These topics are of great interest to the technical committees for a series of sessions, including joint sessions, on Turbomachines for Clean Power and Propulsion.

Turbomachines for Clean Power and Propulsion Systems is a single track (avoiding overlapping sessions if possible) that will address the various aspects of this emerging area. This topic, which is also the conference theme, will be highlighted at the keynote session. It will be followed by plenary and panel sessions with experts discussing the challenges and impact of this latest trend and technical sessions that will delve deeper into this subject. It is planned to supplement the Turbomachines for Clean Power and Propulsion track with exhibitors showing their latest capabilities and equipment. The goal is to generate and capture the basic and applied R&D and know‐how for the Turbo Expo community.

Maintenance, Repair and Overhaul (MRO) for Turbomachinery in the light of Digitalization

The latest trends in digitalization not only affect the way turbomachines are designed, but also have an impact on Maintenance, Repair and Overhaul (MRO). Today, turbomachines are monitored extensively using advanced sensor technology providing data that is processed in sophisticated models. The combination of digital replicas that account for a variety of physical phenomena along with pinpoint repair technology and customized manufacturing is revolutionizing the MRO sector. These aspects were introduced at TE18 in Oslo via plenary sessions, tutorials, panels, and technical papers. The Gas Turbine Segment and IGTI Leadership Team, as well as TE Committees, strongly believe that continued concentration on MRO/Digital during TE19 will benefit the Turbo Expo community.

Many of the TE Committees are interested in MRO/Digital. For TE19, abstracts for technical papers on the various aspects of MRO/Digital have been submitted. These topics are of high interest to the technical committees for a series of sessions, including joint sessions, on MRO/Digital.

MRO/Digital is a single track (avoiding overlapping sessions if possible) that will address the various aspects of MRO/Digital for turbomachinery. The focus track will have tutorial and panel sessions to build upon the momentum from 2018, and, along with technical papers discuss the impact of latest trends in digitalization and advanced repair technologies on the MRO sector. It is planned to supplement the MRO/Digital track with exhibitors showing their latest capabilities and equipment. The goal is to generate and capture the basic and applied R&D and know‐how for the Turbo Expo community.
