Flight Loads


ZONAIR - Advanced Engineering Software

ZONAIR Description
ZONAIR is an advanced engineering software application used for computation of aircraft flight loads that can include aeroelasticity and aerothermoelasticity effects. The resulting flight loads are used by structural engineers for performing detailed stress analysis of the aircraft structure. ZONAIR utilizes a unified high-order subsonic/supersonic/hypersonic panel methodology as the underlying aerodynamic force generator to efficiently create aerodynamic and loads databases for 6 degree-of-freedom simulation and critical loads identification. ZONAIR's unstructured surface panel scheme is compatible with the finite element method so that existing pre-processors, such as Patran and Femap, can be used to set up the aerodynamic model. ZONAIR employs a vortex roll-up scheme for high-angle-of-attack aerodynamics and includes ZAERO's advanced Trim module for flexible loads analysis and a Thermal Protection System for Optimization (TPSOPT) module for aerothermoelastic analysis.
