ZONAIR is an engineering software product used to compute steady aerodynamics of a flight vehicle. ZONAIR employs a high-order panel-based methodology for computation of aircraft flight loads with static aeroelasticity effects accounting for higher-fidelity (than ZAERO) wing-body geometry and blend-wing/body configurations. ZONAIR requires interfacing with a structural finite element analysis (FEA) software program such as MSC.NASTRAN l.c. to obtain structural-vibration/model results. 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
