ZAERO - ZONA Technology, Inc.

ZONAIR is engineering software used to compute steady aerodynamics of a flight vehicle. ZONAIR employs a high-order panel-based methodology for computation of aircraft flight loads that can include aeroelasticity and aerothermoelasticity effects. Some of ZONAIR's capabilities and features include:

A unified high order subsonic / supersonic / hypersonic panel methodology as the underlying aerodynamic force generator
Unstructured surface panel scheme compatible with finite element methods
Direct adoption of off-the-shelf FEA pre- and post-processors (e.g., PATRAN, Femap, I-DEAS, etc.) for rapid panel model generation
Vortex roll-up scheme for high angle-of-attack aerodynamics
Trim module for flexible loads and aeroheating module for aeroheating analysis
Can import CFD solutions and map the pressure from CFD grids to ZONAIR panels. Based on the mapped CFD Cp as the rigid loads, ZONAIR can compute incremental flexible loads
AIC correction using wind-tunnel measured loads for accurate flexible loads generation
Aerodynamic and loads database for 6 d.o.f. simulation and critical loads identification
Provides all stability derivatives including control surface deflections without modifying the panel model
Performs a trim analysis and automatically maps the forces from ZONAIR panels to NASTRAN structure grids for subsequent stress analysis
Computes flexible loads due to structure flexibility and provide Elastic-to-Rigid ratios of all stability derivatives
Can perform Aeroheating analysis to provide heat rate and temperature solutions on the surface
