NASA Spinoff

Originating Technology/NASA Contribution

While working on designs for a new high-speed aircraft, a group of software engineers at NASA’s Langley Research Center developed a program that helps create lighter weight vehicles, while still maintaining strength and structural integrity. Part of the National Aerospace Plane project, the software was necessary to allow designers to easily experiment with new materials and structures, trying a variety of different options for building what would have been the world’s fastest aircraft, the X-30—capable of taking off from an airport in Washington, DC, accelerating to over 20 times the speed of sound, and landing in Tokyo in under 2 hours.

In an aircraft like the X-30, what President Ronald Reagan said could potentially be the next “Orient Express,” the benefits realized by weight reduction become critical, while the demands placed on the vehicle’s structure are greatly magnified. Weight reduction translates directly into fuel savings, increased payload, and greater flight range, but that kind of speed places an incredible strain on an aircraft.

Named “ST-SIZE” and developed over the course of several years from 1988 to 1995, the software NASA developed for solving this issue allowed for weight reduction through optimizing use of composite materials—helping designers quickly and easily experiment with the full range of effects that individual parts composed of varied and nontraditional materials would have on the vehicle.


While the Agency had long been known for bringing its cutting-edge technologies to the public sector in the forms of commercial spinoffs, it was not until 1996 that NASA had ever licensed software to a private company. In that year, the National Aerospace Plane project came to an end, unrealized, but with many technologies ready to be applied to new missions and additional aerospace research. It was then that Langley’s Craig Collier licensed the ST-SIZE software he had helped develop for the X-30 and struck out on his own to bring the software to the broader market.

As Collier explains, the company founders knew “NASA would again need the capabilities, but in a commercially robust software package, so it made sense to step up the development for the purpose of making it better so that customers like NASA would want to use it.”

The company he formed, Collier Research Corporation, of Hampton, Virginia, wrote a more capable and robust code based on the ST-SIZE software and now markets it under the name HyperSizer. It has been used in everything from designing next-generation cargo containers, to airframes, rocket engines, ship hulls, and train bodies. Most recently, it was adopted by Bombardier Inc. for design and analysis of the new all-composite Learjet 85. With over 300 companies, projects, and divisions using the software and sales topping $4 million a year, the small software startup has been expanding rapidly in recent years.

As Collier originally intended, the technology has also taken a spin back into NASA, where it is now being used to analyze designs for NASA’s newest space vehicles. “In the beginning,” Collier says, “it was a scenario where we were taking NASA technology and applying it to industry, but we have been able to work with industry to understand new details and issues and then take these lessons learned from industry and build capabilities. NASA now benefits from these newfound capabilities in designing hardware and making components.”

After years of modifications and updates through applying the software to work on high profile projects with Langley, Marshall Space Flight Center, Glenn Research Center, Ames Research Center, Lockheed Martin Corporation, Boeing, Gulfstream, Scaled Composites, Goodrich, Bombardier, and the Air Force Research Laboratory, the company received several Small Business Innovation Research (SBIR) contracts to apply HyperSizer to nearly all aspects of the new Orion crew exploration vehicle design. The company is now also fundamentally involved in the development of both the Ares I and Ares V launch vehicles.

Collier cites the NASA-licensed technology as helping the company gain audience with new customers, but says that it is really the continued partnership with the Space Agency that has kept the company competitive. “Just the association has gotten the foot in the door,” he explains, “but that only goes so far. The other thing is to be able to demonstrate that it is good technology and to do that we have continued to stay in step with NASA’s technology. It keeps us on the cutting edge.”
