Gas Turbine Technology

This course is a comprehensive introduction and overview of the gas turbine engine and its principal components. Coverage includes turbojet, turbofan, and derivative engines for power generation, and the course is intended to provide a simple and self-contained description of the principles and understanding of these engines. Extensive use is made of modern computer-based design and analysis tools to illustrate and expand on topics covered in the course. In this way participants will be exposed to the best current design practices. It is appropriate for starting engineers, and engineers experienced in other fields who find themselves called upon to undertake work in this area.

Participants earn 2.7 Continuing Education Units (CEUs).
