TURBO-AE: An Aeroelastic And Multi-stage Aerodynamic Analysis Code Based On Unsteady Three-dimensional Navier-Stokes Equations
An aeroelastic and unsteady aerodynamic analysis code has been developed for prediction of flutter, forced response, performance and rotor-stator interaction effects. The analysis provides a high-fidelity modeling of subsonic, transonic and supersonic flow regimes with attached and separated flow fields. The code calculates performance quantities such as efficiency, mass flow, pressure ratio, temperature ratio, distribution of flowfield properties in the entire domain of calculation, aerodynamic damping to assess flutter stabiltiy and unsteady aerodynamic forces arising from rotor-stator interaction for calculation of forced response. This information can be used in high cycle fatigue analysis of blade rows.

Ozone: ODE and Optimal Control Solver
Ozone is a Python software package that facilitates the solution of ordinary differential equations (ODEs) and optimal control problems. It is unique among similar libraries because of its capability to compute derivatives of the ODEs integrated outputs with respect to parameters, initial conditions, and the time interval. This is implemented in a manner that allows Ozone-based ODE models to be integrated in larger, potentially multidisciplinary models while using adjoint-type methods to compute derivatives for the larger model. In terms of the ODE integration, Ozone adopts the general linear methods (GLM) equations, allowing it to easily support a large library of Runge-Kutta and linear multistep methods. Ozone also supports multiple integration formulations, consisting of time-marching, solver-based, and optimizer-based approaches to solving the ODE. Ozone is built on top of NASAs OpenMDAO software framework.

RACE - Runtime for Airspace Concept Evaluation
RACE is a software architecture and framework for configurable, highly concurrent and distributed message based systems. RACE can be used to rapidly build simulations that span several machines (including synchronized displays), interface existing hardware simulators and other live data feeds, and incorporate sophisticated visualization components such as NASAs WorldWind viewer. RACE is implemented as a distributed actor system that runs within Java virtual machines.

LAR-18901-1
Higher-fidelity Conceptual Design and Structural Optimization (HCDstruct) Version 2.0
HCDstruct V2.0 represents the second major development of the HCDstruct software tool. In V2.0, HCDstruct now includes an aerostructural modeling and optimization capability for generalized tube and wing aircraft configurations. This tool permits the rapid, parameterized creation of aeroservoelastic finite-element models for general tube and wing aircraft configurations and constructs all files required to perform the subsequent aerostructural optimization using the NASTRAN software. The methods employed offer a novel physics-based sizing capability for unconventional aircraft configurations for conceptual design environments.
