The TETS Symposium is a biennial forum where the United States' turbine engine community gathers to review and discuss the latest turbine engine technology advances. The Symposium draws an audience of approximately 1,000 engineers, scientists, managers, and operational personnel from throughout the turbine engine community; including the Army, Navy, Air Force, NASA, DARPA, DOE, FAA, engine and aircraft manufacturers, material and component suppliers, and academia. Beginning in 2018, the TETS Symposium expanded its scope to include an increased emphasis on review and discussion of critical complementary technologies in the areas of aircraft power generation and thermal management. Over three days of technical presentations, supported by relevant hardware displays, will underscore the United States' commitment to advance the state of the art in gas turbine engine technology. The audience is limited to US Citizens only via DD2345.
