Topic Description

Materials & Manufacturing

All aspects of material development and manufacturing, especially high temperature materials and advanced manufacturing methods for cost reduction or complex parts. Includes additive manufacturing and nonmetals.

Transient Power Needs in Future Aircraft

Power and thermal needs in future aircraft continue to grow, especially in light of advanced sensors and weapons. This workshop will discuss engine technologies designed to provide the power and thermal dissipation needed by these advanced systems.

High Mach Turbine Engines The design and testing of turbine engines above Mach 2. Discussion may include inlets and exhausts as well as technologies associated with combined cycle concepts.
