F-22 Structural Coupling Lessons Learned

A survey of current F-22 aeroservoelastic analysis and testing activity shows that valuable insight has been gained into several structural coupling and ride quality problems. The aeroservoelastic (ASE) analysis results agree well with flight and ground test measurements. Examples from a recent stru...

Description
Summary:A survey of current F-22 aeroservoelastic analysis and testing activity shows that valuable insight has been gained into several structural coupling and ride quality problems. The aeroservoelastic (ASE) analysis results agree well with flight and ground test measurements. Examples from a recent structural coupling test will be used to illustrate some recent F-22 ASE issues. Presented at the Specialists' Meeting of the RTO Applied Vehicle Technology Panel (AVT) held in Ottawa, Canada, 18-20 Oct 1999.
