Flight Loads


ZAERO - A Powerful Engineering Suite



ZAERO, integrates all essential disciplines required for advanced industrial aeroelastic design and analysis. ZAERO's unique high-fidelity geometry module allows you to accurately model wing-body configurations including underwing naceles/stores. It's unified AIC scheme provides the capability to run subsonic, transonic, supersonic, and hypersonic Mach numbers with a single aerodynamic model. ZAERO has a built-in finite element analysis output file loader that can readily import free vibration analysis results from numerous available commercial products including (MSC.Nastran, IDEAS, ELFINI, Abaqus, Ansys, and others).

A Unified Aerodynamic Influence Coefficient (UAIC) matrix scheme allows for flutter, static aeroelastic and aeroservoelastic analyses to be performed in subsonic, transonic, supersonic, and hypersonic Mach numbers. A high fidelity geometry package provides for easy modeling of complex aircraft configurations that can include fuselage, stores, engine inlets, etc. Built-in spline methods establish accurate interfacing between structural FEA and aerodynamic models. Structural modal results are directly imported from other commercial FEA codes. ZAERO's modal importer currently supports numerous FEA codes including MSC.Nastran, UAI Nastran, CSA Nastran, NE Nastran, ASTROS, I-DEAS, ELFINI, Genesis, and a free-formatted input for use by any other FEA software. Versatile graphic output capability allows for viewing of all facets of the aeroelastic analysis and design process using a host of commercially available graphic software packages. ZAERO is a professional software engineering tool that can efficiently solve your most demanding industrial aeroelastic and aeroservoelastic problems.
