Course Description
An extensive review of vehicle structures, loads and flutter testing takes the student from basic properties of materials through advanced instrumentation methods for determining flutter regions and divergence. Industry standards for determining loads limits and freedom from flutter are addressed as well as possible ways for obtaining required data in a limited amount of flight time. A study of the instrumentation installation on an Aeromacchi MB-326 Impala aircraft enhances the students’ knowledge of the correct test methods for in-flight loads determination. Stores clearance may be considered an extension of aircraft loads and flutter testing. Unique stores load and flutter issues are examined as well as theory and methods for clearing stores for external carriage and separation/launch.
