Company to develop and release DATC, a design tool for engineers at NASA and in other industries to design, analyze lightweight structures

WEST LAFAYETTE, Ind. – NASA has awarded a $799,954 Phase II STTR contract to AnalySwift LLC, a Purdue University-affiliated commercial software provider. The company will develop DATC, or Design tool for Advanced Tailorable Composites, and launch it at the end of the two-year contract.

Allan Wood, AnalySwift president and CEO, said advancements in simulation capabilities have not always kept pace with those in manufacturing techniques. He said DATC will significantly improve NASA’s capabilities to design and analyze aerospace structures made from advanced tailorable composites.

“DATC will be used to design next-generation aerospace structures, such as hybrid/blended wing bodies, space launch vehicles, space habitats and payload attach fittings,” Wood said. “These structures made from advanced tailorable composites will be lightweight and have enhanced performance.”

Traditional composites consist of straight fibers in a matrix, which make predicting their properties more straightforward, Wood said. Advanced tailorable composites are not limited to straight fibers.

“These materials include tow-steered composites, in which fibers are steered along curvilinear paths instead of traditional straight paths, and variable thickness composites in which layers, often called plies, vary in thickness or drop off altogether. The materials can be reinforced with either continuous or short fibers,” Wood said.

“This customization can facilitate drastic reductions in structural weights and/or improvements in the load-bearing capacity, though the increased complexity renders it much more difficult to accurately predict their properties.”

AnalySwift will integrate several tools to create DATC. 

“DATC will be based on mechanics of structure genome, or MSG, and its companion code SwiftComp, which was developed at Purdue University,” Wood said. “It also will include third-party structural solver tools, a general-purpose optimizer and a machine learning package. These tools will be integrated into a unified and intuitive design framework.” 

Wood said without a simulation tool for advanced tailorable composites, engineers must rely only on costly and time-consuming physical experiments instead of supplementing them with virtual testing and design.

“This often leads components to be overbuilt and over budget,” Wood said. 

Wenbin Yu, a professor in Purdue’s School of Aeronautics and Astronautics, is the principal investigator on the development of DATC. Su Tian of AnalySwift and professor Xin Liu of the University of Texas at Arlington are co-investigators.

“This project will use the mechanics of structure genome and the companion code SwiftComp, recently developed at Purdue, to provide efficient yet accurate solutions for advanced tailorable composites,” Yu said. 

Wood said AnalySwift expects to complete DATC when the Phase II project ends in December 2024.

“We plan to release DATC to NASA engineers and others interested in this product,” Wood said. “Engineers can use DATC to create innovative, lightweight solutions for systems critical for national security, the environment, transportation, the economy and more. Besides NASA, other related government agencies and industries will be benefit from using DATC to design better engineering systems with reduced experiments and further adjustments, which lowers engineering time and cost.”

In 2022 AnalySwift received two Phase I STTR contracts from NASA, a one-year contract for $120,000 and a 13-month contract for $156,000. The company licenses Purdue University intellectual property through the Purdue Research Foundation Office of Technology Commercialization. This work was also supported by Elevate Ventures and the Indiana Economic Development Corporation.
