checkSolution Features

  • Dynamic memory and database management system ensures program modularity and allows for virtually unlimited problem size
  • Executive control allows for massive flutter/ASE/trim inputs and solution outputs
  • Matched/non-matched point flutter solutions with true aerodynamic damping (includes a unique flutter mode tracking capability and flutter sensitivity analysis)
  • Steady/unsteady aerodynamics at subsonic, transonic, supersonic and hypersonic Mach numbers with no change to aerodynamic model

checkLoads and Boundary Conditions

  • Static aeroelastic/trim analysis for flight loads at symmetric, antisymmetric and asymmetric maneuver conditions
  • Dynamic loads
  • Flutter
  • Ejection
  • Maneuver
  • Gust
  • State-space aeroservoelasticity for stability analysis and gust loads

checkPerformance and Control Features

  • Uses the most current advances in finite element technology
  • Extensive error checking at all stages of execution
