Calvin R. Jarvis

Calvin R. Jarvis for a decade was Dryden's deputy director or director of the Dryden Aerospace Projects Office.

Guidance and flight controls, electronics, handling qualities, and integrated systems were Jarvis' specialties. He worked extensively in the research, development, evaluation and management of numerous state-of-the-art flight control systems beginning with the X-15, the Lunar Landing Research Vehicle, the F-8 Digital Fly-By-Wire program, the F-18 High-Angle-of-Attack Research Vehicle development, to name a few.

Jarvis was a key F-8 DFBW flight research program advocate and project manager for phases I and II. The F-8 DFBW program was instrumental in establishing the baseline hardware and software requirements used in the development of advanced digital flight controls for military and commercial aircraft, including the shuttle. DFBW technology evolved out of the LLRV program; the LLRV had an analog fly-by-wire system.

He served as director of the Dryden Aerospace Projects Directorate, through which Dryden's flight research projects were managed. These included joint activities such as the NASA and U.S. Department of Defense X-29 forward swept wing aircraft and X-31 experimental aircraft programs to in-house flight research experiments such as the F-18 HARV. He also was part of the management of a cooperative NASA and Russian International Aerospace program to refurbish and utilize a Tu-144 supersonic airliner as a testbed in support of a joint NASA/industry program to develop a commercial hypersonic transport aircraft.

Jarvis was deputy director of the inter-agency F-16 AFTI joint test force through which the first Air Force operational digital fly-by-wire flight control system was developed. He served as director of the Ames Research Center, Moffett Field, Calif. and Dryden National Aerospace Plane Project Office. He also authored 20 NASA technical publications and reports.

Gary E. Krier

Gary E. Krier is a former Dryden research pilot and director of several departments within Dryden.

He is best known as a team member and project pilot for the F-8 Digital Fly-By-Wire aircraft, co-project pilot for the F-8 Supercritical Wing project and project pilot of the Integrated Propulsion Control F-111E.

He also is known for leading the initial effort to consolidate aircraft operations and form the Airborne Science organization at Dryden using the aircraft transferred from Ames Research Center, Moffett Field, Calif.

Krier was an aerospace research pilot and engineer at Dryden after first starting to work at NASA in 1967. He was the first pilot to fly the F-8 DFBW aircraft and the Integrated Propulsion Control System F-111E with digital fuel and inlet control. The F-8 DFBW was the first to be used to validate the concept in 1972. It was the forerunner of the fly-by-wire flight control systems now used on the space shuttles and on today's military and civil aircraft to make them safer, more maneuverable and more efficient.

In addition, he flew the YF-17 research aircraft and has flown more than 30 types of aircraft ranging from light planes to the NB-52B and the triple-sonic YF-12.

He served in numerous positions during his Dryden career, including acting deputy director, chief engineer, director of the Systems Management office, and director of the Airborne Science directorate. He also headed the center's Aerospace Projects directorate and led the Intercenter Aircraft Operations directorate.

Krier also served in several NASA Headquarters positions as well, his last in 1994.

He served for two years as manager, Operations and Facilities, for the New Launch System. Prior to that assignment, he held two management positions at Headquarters relating to space shuttle operations.

Krier also was director of the Commercial Development Division, Office of Commercial Programs, and as director of the Aircraft Management Office. At Ames, he was an attorney in the Office of the Chief Counsel.

Wilton P. Lock

Wilton P. Lock is described by his nominators as one of Dryden's many unsung heroes and pioneers. Lock has been at the center for more than 40 years.

An often quiet and soft-spoken man, when Lock speaks, people listen, according to his nominators. He was instrumental in the development, flight test and success of the F-8 Digital Fly-By-Wire research program, one of Dryden's most significant contributions to modern flight controls. That project (see entry on the F-8 DFBW) had significant influence on the flight controls not only for modern civilian and military aircraft, but also for NASA's fleet of space shuttles.

As operations engineer for the F-15B, Lock contributed to the success of the Active Controls Technology for Integrated Vehicles project, in which new engine technologies such as thrust vectoring (using the engine's thrust for directional control) were demonstrated. He also is a team member for the F-15B Intelligent Flight Control System programs. IFCS efforts are focused on developing concepts such as health monitoring and adaptive flight controls.

Nominators also praised Lock's knowledge and experience with the aircraft. That experience has been vital to keeping the aging aircraft available for flight research projects.

In addition, Lock contributed for more than four decades to Dryden projects involving the X-15 aircraft no. 1 and no. 2; the Lunar Landing Research Vehicle simulation; the XB-70 no. 1 Structural Mode Control System; and the F-8 Super Critical Wing.

Lock also worked on the F-111 Mission Adaptive Wing; the increasingly complex projects on the F-15 Highly Integrated Digital Electronic Control; the F-15 Self Repairing Flight Control System; and the MD-11 Propulsion Controlled Aircraft.

Lock also has been an inspiring mentor to many engineers, according to his nominators, some of whom he helped start their careers.

Betty S. Love

Betty S. Love came to the NACA Muroc Unit in 1952 to work as a "computer."

Women were hired by the NACA and by most military branches as "computers" to reduce raw data into something engineers could read. The exception was the Navy, which replaced its women computers with the Electrical Numerical Integrator And Calculator, or ENIAC. Love read and time-marked film, transferred data points to paper, and graphed research results derived with various X planes. One such task was reducing the film data from the X-1A's Dec. 12, 1953, flight, during which the aircraft experienced violent instability and tumbled before the pilot recovered the aircraft.

By 1955 she had risen to Aeronautical Engineering Technician in the Aero Structures Branch. There she worked closely with engineers in data analysis and the creation and presentation of flight reports. She was co-author on several professional papers.

She also became keeper of the flight logs for all three of the X-15s and for two XB-70 flights. In addition, she became the holder of pertinent data on the aircraft, data needed for configuration changes, and photographs documenting the programs.

She retired in 1973, but returned in 1996 as a volunteer in the center's history office, where her experience and knowledge have been invaluable, according to nominators. In addition to cataloguing various collections in the history office collection, she is one of the few who can identify faces in historic photos, either from her own memory or through the contacts she maintains. Betty Love represents one of the rare links to the center's early history and helps to bridge the center's past and present.

Another of Love's many contributions was her work to gather film clips featuring former pilot Joe Walker, also included on this list of Dryden's Driving Forces, for the 1960s-era movie made about Walker entitled "Pathway to the Stars."
