- Capstone Design
The design of gas turbine exhaust ducts affects the external aerodynamics of the engine installation. The exhaust duct in combination with the nacelle affects the lift and drag of the installation. When optimizing exhaust ducts for internal aerodynamic performance, the effect of lift and drag must also be assessed.
Using wind tunnel testing of scale models of the aircraft installation including the nacelle, exhaust duct, and wing, the external aerodyamics can be assessed over a range of angles of attacks.
