Truax, Robert Collins was born on September 3, 1917 in Gary, Indiana, United States. Son of Darwin Hoskins and Alida Retta (Gleason) Truax.
Bachelor of Science in Mechanical Engineering, United States Naval Academy, 1939. Bachelor of Science in Aerospace/Agricultural/Architectural/Aeronautical Engineering, United States Naval Postgraduate School, Monterey, California, 1952. Master of Science in Nuclear Engineering, Iowa State College, 1953.
Truax was a proponent of low-cost rocket engine and vehicle designs. As a teenager, Truax was inspired by Robert Goddard articles in Popular Mechanics magazine to build his own rockets while residing in Alameda, California. From 1936 to 1939, midshipman Truax tested liquid-fuel rocket motors and published a February 1939 report in Astronautics.
In 1938, he showed a thrust chamber that he had constructed to the British Interplanetary Society and wrote technical reports published by the American Rocket Society.
Following two years" sea duty, first on the United States Ship Enterprise (CV-6) and then a destroyer, then-Lieutenant Commander Truax worked at the Engineering Experiment Station at Annapolis in the Bureau of Aeronautics Ship Installations Division under Commander C. A. Bolster. Truax headed the Navy Development Project (ensigns R C Stiff, J F Patton, West Schubert and Massachusetts Institute of Technology civilian Robertson Youngquist), where hypergolic propellant was discovered—fuel that burst into flame spontaneously when brought into contact with nitric acid, leading to the use of aniline plus 20% furfuryl alcohol for the 1945 Women's Army Corps Corporal (the first free-flight rocket to use the fuel).
By early 1943, the Truax group had developed a 1,500 lbf (67 kN) thrust JATO using hypergolic fuel before the introduction of solid fuel JATO units. From 1955 to 1958, Truax was assigned to the United States Air Force under General Bernard A. Schriever, where Truax and Doctor Adolf Thiel headed the initial design studies and IRBM specifications for the PGM-17 Thor missile.
Truax subsequently worked on the Navy"s Viking rocket and UGM-27 Polaris missile.
Truax studied the sea launching of rockets, such as the Sea Bee and Sea Horse projects. After serving as 1957 American Rocket Society president, Truax retired from the United States Navy in 1959 and headed the Aerojet-General Advanced Development Division and Aerojet"s Sea Dragon project In 1966 Robert Truax founded, which studied sea launch concepts similar to the earlier Sea Dragon—the Excalibur, the SEALAR, and the Excalibur South.
Truax also designed the Skycycle X-2, which he unsuccessfully tested on April 15, 1972 and June 24, 1973, and which Evel Knievel unsuccessfully used at the Snake River Canyon in 1974.
The X-3 (other names: Arriba One, Skycycle X-3) was a reusable space tourism rocket planned by Robert Truax after Evel Knievel provided a $1,000 research grant for a pilot study.
Truax was looking for volunteers with enough money to help fund the effort and who wished to fly aboard his rocket. He got thousands of volunteers, but few of them had the financial resources.
Among those who offered some financing and who went through some of his training, were astronauts: Ronald Beller, a pilot from Kentucky, Martin Yahn, Ray Upton, Peruvian-born Daniel J. Correa and Fell Peters, all of southern California. The rocket used surplus components and was tested through 1991.
Fellow American Institute of Aeronautics and Astronautics, American Rocket Society (president 1957, Goddard meal).
Married Rosalind Heath Schroeder, July 19, 1941 (divorced October 1964). Children: Ann Heath, Kathleen Rosalind, Steven Robert, Gary Hale. Married Sally Ann Sabins, October 11, 1964 (deceased June 1992).
Children: Scott Alan, Dean Shepard. Married Marisol Guzman-Acero, December 10, 1994.
