CREATE-AV Kestrel calculations of an F-16 and boom while maneuvering in refueling position behind a notional tanker aircraft. Instantaneous vorticity isosurfaces colored by pressure are shown. The simulations required ~2000 compute cores and were accomplished at the AFRL DSRC.
About CREATE- AV
The CREATE-AV project is tasked to develop, deploy, and support a set of multi-disciplinary, physics-based simulation software products for the engineering workforces, supporting air vehicle acquisition programs of the services. These products are designed to exploit the capabilities of next generation computational resources while also increasing the productivity of the engineering workforce. This is accomplished through streamlined, more efficient engineering workflows and computational physics models, enabling the detection of design flaws and performance anomalies early in the aircraft development. Our software suite includes: Kestrel, Helios, and ADAPT.
Kestrel is the software product produced by the fixed-wing development group of the CREATE Air Vehicles project (CREATE-AV). Its primary purpose is to reduce the cost of acquiring new fixed-wing aircraft by making accurate, timely, and easy-to-use simulations available to every participant in the acquisition process, including early designers and contractor partners. Kestrel is comprised of two major pieces. The first major piece is the Kestrel User Interface (KUI) which serves as the main “face” to the user, allowing for simulation input and postprocessing. The second piece is the runtime Common Scalable Infrastructure (CSI) which serves as a flexible “message broker” for all computational components during runtime.
Helios is a high-fidelity multi-disciplinary computational analysis platform for rotorcraft aeromechanics applications. Helios handles the aerodynamics solutions in an innovative manner, using a dual-mesh paradigm: unstructured meshes in the near-body region and Cartesian meshes in the off-body region.
Helios is comprised of three main components. The first is the Helios preprocessor (preproc), which handles mesh assembly and partitioning. The second is the Helios GUI (hui), which allows the user to input simulation parameters. And the final piece is the Helios runtime environment (CSI).
ADAPT (Aircraft Design, Analysis, Performance, and Tradespace) is CREATE-AV’s fixed-wing aircraft conceptual design framework. ADAPT allows aircraft designers to easily integrate and use multi-disciplinary tools in a common framework, explore the aircraft design tradespace, and leverage HPC resources at the conceptual design stage.
ADAPT is comprised of three major pieces. The first is the extensible ADAPT data structure, which provides the common framework for integrating multi-disciplinary tools. The second is the ADAPT GUI, which enables conceptual designers to easily set inputs, document work, and analyze results. The final piece is the ADAPT execution engine, which runs the integrated multi- disciplinary toolset on desktop or HPC machines.
ADAPT is limited to US Government use only, and requires a separate license agreement.
