We deliver reliable solutions for aeroelastic stability compliance and certification of air vehicles.
Services
-

Modeling
Finite element model (FEM) and doublet-lattice model development, aerodynamic panel corrections to CFD or wind tunnel data, aeroservoelastic (ASE) state-space model development, FEM correlation to ground vibration testing (GVT), FEM mass modeling, and implementation of solutions to mitigate flutter.
-

Analysis
Flutter analysis, divergence, ASE stability margin analysis (state-space and frequency domain), freeplay analysis, fail-safe analysis and parametrics (actuator stiffness, hinge moment effectiveness, store loadings, control surface weight and CG variations, etc.), documentation and flight clearance recommendations.
-

Ground Test
Test planning, pretest analysis, fixture design, test execution, data review, and documentation for GVT, component tap testing, structural coupling testing (SCT) or structural mode interaction (SMI) testing, control surface freeplay testing, and control surface mass property measurement (weight, CG, hinge line inertia).
-
Flight Test
Flutter flight test planning, instrumentation planning, flutter excitation system development, test point development, test plan documentation, IADS display development, flight test readiness reviews, test execution and flutter real-time monitoring, data reduction, data reviews, and flutter flight test certification documentation.
