  • Efficient Simulation of Structural Dynamic Systems with Discrete Nonlinearities

    Dynamic loading environments often involve complex loading and boundary conditions. For the case of externally mounted aircraft stores, qualification testing involves simulating this environment with relatively simple test fixtures and load application shakers.

  • Efficient Creation of Aeroservoelastic Models Using Interpolated Aerodynamics Models

    The expense of running computational fluid dynamics (CFD) and computational structural dynamics (CSD) codes motivates the creation of aeroservoelastic models which can be interpolated accurately to unmodeled flight conditions.

  • Estimation of Unsteady Loading for Sting Mounted Wind Tunnel Models

    Measurement of static loads is conventionally performed using a linear combination of strain gage measurements. For the case of a loading environment with energy content in the same frequency band as structural modes, measurements can be significantly corrupted.

  • Developing the Aerodynamics Module for the Integrated Multidisciplinary Optimization Object System

    The Integrated Multidisciplinary Optimization Objects (IMOO) System delivers physics-based multidisciplinary analysis and optimization (MDAO) capabilities that are required to develop next generation subsonic, supersonic, and hypersonic aircraft.
