NEiAeroelasticity (ZAERO) has extensive capabilities in the areas of aero-elasticity, aeroservoelasticity, unsteady aerodynamics and structural dynamics.

NEiAeroelasticity provides analysis capability for the following solution types:

  • Flutter
  • Static Aeroelastic
  • Aeroservoelastic
  • Flutter with Nonlinearity

Capabilities

  • Solution 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
       
  • Loads 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
       
  • Performance and Control Features
    • Uses the most current advances in finite element technology
    • Extensive error checking at all stages of execution
    • Bulk data input is very similar to NASTRAN, cutting down learning time
    • Modal data importer automatically imports FEM modal data output directly from NASTRAN
    • Open architecture design allows the user direct access to all data entities (a completely programmable environment)
    • Unified AIC matrices can be stored for repetitive structural design and analysis
       
  • Modeling Features
    • High fidelity geometry module allows for realistic modeling of aircraft configurations, including the fuselage, stores, nacelles, etc.
       
  • Output Features
    • 3D spline provides accurate displacements and force transferal between structural FEM and aerodynamic models
    • Graphic output of aerodynamic model, unsteady pressures, interpolated structural modes, flutter mode animation, and more
       
  • Transient Heat Transfer
    • Linear and nonlinear
    • Conduction, convection, and radiation
       
  • Buckling Analysis
    • Critical loads and mode shapes
    • Linear and nonlinear initial stress
       
  • General (supported in all solutions)
    • Composite laminate materials
    • Temperature dependent materials
    • Direct matrix import & export (DMIG)
