The Aerostructures Branch at NASA Armstrong is a highly integrated team that covers the breadth of the airframe structures disciplines including static structures, structural dynamics, external and aerothermal loads, and hot structures. The team is also well versed in traditional and advanced structural instrumentation technologies.

The strength of the branch is its talented engineers who each have experience in analysis, ground test, and flight test. This breadth of experience allows our engineers to appreciate the advantages and limitations of each of these areas as flight projects are developed and progress from design and analysis to ground test to flight and to provide expertise to ensure safe and effective missions. The branch has resident experience in flight projects that range from extremely lightweight, high-altitude aircraft to transports and high-performance military aircraft to hypersonic vehicles.
