SDI Engineering’s ASSURE is a set of probabilistic aeroservoelasticity tools, developed in collaboration with the University of Washington.

​

ASSURE’s unique capabilities are applied to isolate uncertainties in simulation, manufacturing, test measurement, and test-to-analysis correlation.

 

The toolbox is used to analyze the aeroelastic/aeroservoelastic characteristics of advanced flight vehicles in flight and on the ground.

 

ASSURE is designed to have significant flexibility in the types of problems analyzed, the solution methods used, and how problems are defined.
