  • Loads and dynamics including flight and ground loads
  • Flight control systems including actuators, hydraulics, control laws and handling qualities
  • Landing gear systems
  • Structural design and classical stress analysis, finite element modeling, and fatigue and damage tolerance
  • Aerodynamics and computational fluid dynamics (CFD)
  • Aerial refueling
  • Vibration
  • Aircraft modification and certification
  • Full testing services including static loads, ground vibration (GVT), flutter, test management, reporting and certification
SDI utilizes commercial software tools including:  Femap, Patran, NASTRAN, Abaqus, MATLAB, Simulink, SimMechanics, SimScape, SimHydraulics, SolidWorks, CATIA V5, Star CCM+ and others.  The company has developed proprietary software tools that have led to multiple US government sponsored SBIR/STTR research and development awards.  These tools have been used to perform projects in many of the aforementioned applied areas.
