Accelerate flutter clearance process and increase efficiency in the aircraft certification process

Запись вебинара

Aeroelastic analysis and flight flutter testing are central and important topics in the aircraft airworthiness assessment. Learn how to efficiently process flight test data and get deeper insight into the aircraft structural dynamics.

Guest speaker: Arne Vollan from AeroFEM GmbH

Aircraft manufacturers who seek certification are required to demonstrate compliance to airworthiness regulation.  Flutter and other aeroelastic instability phenomena have a significant influence on airplane development and the airworthiness criteria governing the design of civil airplanes. Moreover since flight tests to the corners of the flight envelope is not risk-free, getting confident results from numerical analysis are necessary in order to obtain an efficient and reliable flutter predictions.

During this on-demand Webinar, we discuss the typical certification by analysis and test process used by general aviation aircraft to prove compliance to aeroelastic airworthiness requirement 23.629 and partially 25.629.

Вы узнаете:

  • How to improve the flight flutter test by using a commercial off the shelf solution to extract accurate eigenfrequencies, damping and mode shapes.
  • The different solutions (static aeroelasticity, flutter analysis and dynamic aeroelasticity) used to define the flight envelope and define accurate flutter predictions.
  • How to tailor this process to your methods.
