Principles of Aeroelasticity

Instructor(s)

Description

Provides an in-depth understanding of aeroelastic behavior for aerospace systems. Explores aeroelastic phenomena, structural dynamics, and fluid-structure-control interaction; also examines practical issues such as ground and flight tests. Includes solution methodologies, state-of-the-art computational methods for aeroelastic analysis, development of the operational boundary, aeroservoelasticity, and contemporary issues such as limit cycle oscillations and related nonlinear pathologies in aeroelastic systems.

Target Audience

Designed for engineers and technical managers involved in aerospace vehicle design, analysis and testing.

Fee Includes

Includes instruction, a course notebook, Aeroelasticity, by Raymond Bisplinghoff, Holt Ashley and Robert Halfman, Introduction to Flight Test Engineering, Volume II, by Donald T. Ward, Thomas William Strganac and Robert Niewohner, refreshments and five lunches. The course notes are for participants only and are not for sale.

Fees: See fee information for individual classes in the registration column on the right side of this page.

Class Time

Comments from Past Participants

"Dr. Strganac managed to take a complicated topic such as aeroelasticity and brings it within the realm of comprehension. I’ve now got a jumping off point to further expand my knowledge of the subject." — Brian Donnelly, 2008 attendee

"I found this course very insightful and useful for my day job. Prof. Strganac is a very accomplished instructor and provided interesting anecdotes and a detailed analysis of many aeroelastic phenomena." — Ciaran O’Rourke, Airbus UK
