UW-Stout's Godfrey conducts NASA
research at Kennedy Space Center

Menomonie, Wis. --- Gary S. Godfrey, associate professor in University of Wisconsin-Stout’s technology department, recently spent 10 weeks at the Kennedy Space Center as a researcher for the NASA Faculty Fellowship Program.

Chosen for his unique software expertise, Godfrey conducted numerous computer-modeling projects as part of his two-year research residency.

In a large hangar that housed collected shuttle wreckage, Godfrey worked to correct a flaw detected in the design of Columbia’s door by altering its shape to better withstand high levels of force. "The door was one of several weak spots, but wasn’t the first part to sustain damage. The wing went first when the heat of the entry penetrated the shield," he said.

According to Godfrey, 3-D computer modeling helped NASA investigate the Columbia tragedy by reconstructing how the heat shield was penetrated "It allowed NASA to see where the wing’s heat tiles were damaged," he said.

Godfrey also worked on 3-D models of the assembly of an orbiter to a shuttle’s external tank, the installation of an Orbital Maneuvering System Pod and the operation of landing gear. NASA will use these models to identify safety issues and train Kennedy Space Center employees. The models will also benefit engineers in their design and analysis efforts.

In addition, Godfrey prepared a depository of 3-D models by accurately translating files from several formats into a single format called Pro/Engineer Wildfire. To do this, he had to determine how to retain as many of the original model’s features as possible. If he could not accurately translate a model, he redrew it from scratch. 

"Translating files between different software programs is an issue for NASA, especially when dealing with older 3-D models," said Godfrey.

The NFFP offers science and engineering faculty from universities across the nation hands-on exposure to NASA’s research challenges. "This opportunity offered me a new perspective. I really feel honored and appreciate receiving this two-year experience," said Godfrey.

A UW-Stout graduate student will join Godfrey in the continuation of his research at the Kennedy Space Center next summer. His travel to and from Florida was funded through a UW-Stout professional development grant. He plans to present his research to groups both on and off campus.
