As Americans are commemorating the 50th anniversary of Apollo 11’s eight-day voyage that included landing on the moon on July 20, 1969, David Elrod, dean of Lipscomb’s Raymond B. Jones College of Engineering has a particular interest in the many documentaries and discussions about the mission and its significance. For nearly four decades, Elrod had his mind on space exploration as a leader and innovator in aerospace technology, and today he is leading the university’s mission to educate the next generation engineers who may take the next historically significant step in space exploration.
Elrod, a 1977 Lipscomb graduate, is an engineer who invested the majority of his career with Jacobs Technology, a global provider of technical, professional, and scientific services, including engineering, architecture, construction, operations and maintenance across the aerospace and defense markets, located in Tullahoma, Tennessee, located about 80 miles southeast of Nashville.
During his tenure at Jacobs Technology, Elrod served as deputy director of the Technology and Development Facility at the Arnold Engineering Development Complex (AEDC); deputy general manager of the AEDC group; vice president, Jacobs Technology, and general manager, Aerospace Testing Alliance, AEDC Group; regional vice president for business development; and most recently as division vice president of business development and technical fellow. Prior to his work at Jacobs Technology, Elrod began his career at Calspan/AEDC as senior lead engineer and research project engineer. From 1989-1995, Elrod was manager of Calspan/AEDC’s Space Technology Department and of its Scene Generator Test Capability, Project Management Office.
In his various roles at Jacobs, Elrod led thousands of employees and secured billions of dollars in contracts and managed nationally critical test operations. He managed design activities related to wind tunnels, hypersonic propulsion test units, space chambers and related electrical and control systems; has interfaced with the United States Air Force, NASA, commercial, and international aerospace customers to assess and define future test and technology needs; led operation and sustainment of the world’s largest complex of flight simulation test facilities; and was capture manager for multiple major pursuits of multi-billion-dollar contracts supporting the USAF and National Nuclear Security Administration among numerous other responsibilities.
Although his exposure to and involvement in space systems began more than a decade after the moon landing, Elrod worked with a number of individuals who had more direct involvement including engineers and craftsmen who were responsible for testing the rocket motor on the ascent stage of the lunar module.
“As most people know, the Lunar Excursion Module carried the astronauts from the Apollo Command Module to the surface of the moon,” said Elrod. “After their stay on the moon, they depended on the rocket motor on the ascent stage of the LEM to fire successfully, blast off and return them to the command module. The cryo-vacuum environment that motor experienced had been simulated at AEDC and developmental motors had been tested there prior to this historic flight. The engineers and craftsmen knew that if that motor failed to operate, the astronauts would be forever trapped on the surface of the moon.”
“So when the news media reported that Neil Armstrong and Buzz Aldrin had successfully taken off from the surface of the moon, a huge sense of relief was experienced in Tullahoma,” he continued. “That rocket motor was but one of thousands of pieces of hardware that had to work correctly for the flight to occur and is a reminder of how engineering can impact history in amazing ways.”
Enabling Neil Armstrong to set foot on the moon was arguably the most significant technological achievement in human history. For me, the clear and simply stated challenge that President (John F.) Kennedy spoke on May 25, 1961 of sending an American to the moon by the end of the decade had enormous impact. — David Elrod, dean, Raymond B. Jones College of Engineering
“Enabling Neil Armstrong to set foot on the moon was arguably the most significant technological achievement in human history. For me, the clear and simply stated challenge that President (John F.) Kennedy spoke on May 25, 1961 of sending an American to the moon by the end of the decade had enormous impact,” he said.
“With those words, he cast a vision that mobilized our nation in a way never before witnessed outside of war. And it brought about alignment of hundreds of companies and an estimated 400,000 individuals to achieve his goal. Contrasting the accomplishments that can occur when individuals united with the challenges that arise when we choose to divide into our own factions makes me appreciate even more the power and impact of such a vision.”
Space exploration is in full force today with the launch period for NASA’s Mars 2020 rover projected for summer 2020, International Space Station initiatives and the next technology that has not yet been discovered.
“Space exploration remains important, not because space is our only frontier, but because it is such a rich frontier to explore in terms of depth, breadth and time. While so much of our earth-bound research is focused on current events, the light striking the earth from space informs us about events which appear to have taken place thousands and/or millions of years ago,” explained Elrod.
“With each boundary we cross, such as with leaving that first footprint on the moon, we gain tremendous knowledge that has applicability to many other aspects of our lives. I am a strong believer in exploration in our personal lives, in our spiritual walks, and in our vocational callings. Through exploration, God’s creation is revealed to us and we see imprints of His work in crossing every frontier.”
The Raymond B. Jones College of Engineering offers programs in civil engineering, electrical and computer engineering, and mechanical engineering — disciplines that are integral to the future of space exploration.
“Each of our engineering disciplines has opportunity to support space exploration,” said Elrod, “Launch systems and space vehicles rely enormously on mechanical engineers to design their structures and systems. Our electrical and computer engineers are deeply involved in the instrumentation, controls, software, communications and ‘smarts’ that enable flight. Civil engineers are involved in arguably the most important parts of safe space flight – the takeoffs and landings.”
“Civil engineers are critical to the design of launchpads, landing strips, processing facilities — such as the Vertical Assembly Building at NASA Kennedy — which are essential for space exploration,” he continued. “Finally, civil engineers are studying regolith, which is the moon’s counterpart to our soil, to understand how it can be used to build structures which can safely house a next generation of astronauts as they continue the journey of exploration.”
Lipscomb engineering graduates have played significant roles in space exploration and continue to be on the front lines of the frontier.
“We equip our students to serve at the forefront of their fields among the brightest, most creative changemakers, and lead their peers with knowledge, innovation, integrity and deep compassion to build a better future,” said Elrod.
Lipscomb alumni who have worked in the aerospace industry include:
Paul Wright, a 2010 mechanical engineering graduate, is involved in renovation of the world’s largest supersonic wind tunnel at the Aerospace Testing Alliance at AEDC, where he has been an engineer since May 2008. Alumnus Chad Jacobs, a mechanical engineer at Jacobs, has been involved in multiple facility design efforts in support of aerospace systems.
Alumni and physics majors Heard Lowry and Wheeler McGregor, were both recognized for lifetimes of contribution to aerospace systems.
Lowry, a 1974 graduate, was selected as an AEDC (Arnold Engineering Development Complex) Fellow due to his contributions in advancing propulsion, aerodynamic and space test technologies critical to AEDC's test mission. His early work focused on molecular spectroscopy and its application in jet engine combustion to determine exhaust gas species concentrations. He worked with nitric oxide concentration measurements using an ultraviolet spectroscopic technique. Lowry also led the development of a laser absorption spectroscopy combustion diagnostics technique for carbon monoxide.
He was instrumental in the development of such systems as the U.S. Air Force Anti-Satellite Miniature Homing Vehicle Sensor in AEDC's 7-foot vacuum chamber, the Laser-Induced Phosphorescence for flow-field velocity measurements, non-intrusive optical diagnostics for the Propulsion Wind Tunnel's (PWT) 16-foot transonic tunnel, the integrated modern optical instrumentation for wind tunnel testing, Doppler Global Velocimetry, laser vapor screen flow visualization techniques, Direct Write Scene Generator project, hardware-in-the-loop testing for the Ground-based Missile Defense program, the Short Focal Length Collimator and the Target Monitoring System. Lowry served as an Aerospace Testing Alliance (ATA) Technical Fellow and a senior engineer with the ATA Integrated Test & Evaluation Department in the Technology and Engineering Analysis Branch.
McGregor, who went to work for AEDC in 1951, was named an AEDC Fellow in 1990. He was honored for his technical leadership and scientific contributions in advancing state-of-the-art concepts in the area of non-intrusive diagnostic techniques and instrumentation in 2005. He is credited with helping to develop a nationally-recognized infrared signature measurement capability at AEDC and using the rocket test facilities to provide key ultraviolet signature data to the early Strategic Defense Initiative program, which subsequently evolved into the Ballistic Missile Defense Organization and ultimately became the Missile Defense Agency.
McGregor also led the establishment of the Plume Data Center, currently known as the Advanced Missile Signature Center at AEDC, a national repository for plume signature data. He also served on numerous national advisory panels to guide the development of the Joint Army Navy NASA Air Force plume codes. That data is used to plan space and satellite missions and to help determine national missile defense policy and research.
