Administrative History
The Ames Aeronautical Laboratory was the second laboratory of the National Advisory
Committee on Aeronautics (NACA). The NACA was created by act of Congress on March 3,
1915 and charged with the development of aeronautical research and testing
facilities to improve both civil and military aviation. By 1917 the NACA had built a
fully operational aeronautical research facility called the Langley Memorial
Aeronautical Laboratory near Norfolk, Virginia. By 1939, American political leaders
recognized that the world was heading toward war and that other nations had
surpassed the United States in basic aeronautical research. NACA leaders recognized
that the Langley laboratory had run out of space for new wind tunnels and was
straining the electrical capacity in the area. Thus, the Roosevelt Administration
forcefully endorsed a report from the NACA Special Committee on Future Research
Facilities, dated December 30, 1938, that argued for the establishment of a second
research installation near the West Coast aircraft manufacturers. The tentative site
suggested was the U.S. Naval Air Field and Army training base at Moffett Field in
Sunnyvale, California. On February 3, 1939 President Roosevelt transmitted the $10
million request to Congress for incorporation into the second deficiency bill. A
stiff partisan political struggle followed, however, and it was not until August 9,
1939, that the funds were approved as a part of the third deficiency bill.
Construction of the second laboratory began on December 20, 1939, led by an elite
group from Langley, whose building priorities indicated a sense of urgency: flight
research building, wind funnels, the technical services facilities, and lastly the
administration building. On April 18, 1940, the center was christened Ames
Aeronautical Laboratory to honor Dr. Joseph Ames, the chairman of NACA from 1927 to
1939 and a staunch advocate for basic scientific research and the responsibility of
the federal government in training people for it. Responsibility for organizing the
center rested with the Engineer-in-Chief, Dr. Smith J. De France, served as Center
Director from 1940 to 1965. Smitty DeFrance was ably assisted by John F. Parsons,
his deputy in charge of administrative matters, by Harry Goett who directed
low-speed wind tunnel research, and Harvey Allen who directed high-speed wind tunnel
research. Allen joked in 1943 that he was actually in charge of "Theoretical
Aerodynamics and Reinforced Concrete" because, in fact, the bulk of everyone's
efforts at Ames was in building facilities as quickly as possible, rather than
conducting research.
The first research effort at Ames involved flight test aircraft rather than wind
tunnels. The Royal Air Force Bomber Command raids over Germany pointed out the need
for a de-icing system to allow aircraft to fly in all types of weather. Within a
year an effective hot-air de-icing system had been developed at Ames for American
heavy bombers, and Ames led the development of methods to test for icing conditions
in actual flight. Lewis Rodert won the 1947 Collier Trophy in recognition of the
outstanding research done at Ames. Later, the knowledge of heat transfer gained in
wing de-icing experiments was applied to problems of jet aircraft and missile
design.
During World War II, Ames kept its wind tunnels in almost constant operation, working
to improve such famous production aircraft as the P-51 Mustang and the P-38
Lightning. A complete set of wind-tunnels was available to West coast manufactures
and their military customers: the smaller 1-by-3 foot tunnel that operated at
supersonic speeds, to the workhorse 7-by-10 wind tunnels, to the 40-by-80 full scale
wind tunnel, then the world's largest. In 1943, the Research Division was split into
two divisions, one for theoretical and applied research and the other for full-scale
flight investigations. In 1944, the technical service group and the technical shops
were combined into the Service Division. Otherwise, Ames' organization changed
little during the war years.
Ames changed more dramatically in the post-war period. In 1953, as a result of the
Hoover Commission on Government Reorganization and its recommendation on
establishing a uniform nomenclature for all governament agencies, sections were
renamed branches, the primary operational unit below the division. Two new divisions
were added at Ames: the High-Speed and Flight Research Division, and the Research
Instrumentation and Engineering Services Division.
Another key addition, in 1950, was the Ames Unitary Plan Design Group. More
high-speed tunnels and more sensitive instrumentation were required for the United
States to compete in the world of jet aircraft and guided missiles. To combine the
talents of NACA, university, military, and industry researchers--as well as to forge
a unified front in lobbying for the enormous funds required--Ames led the formation
of a Unitary Plan wind tunnel design group. This group was to design a series of
high-speed wind tunnels located wherever such research was needed, at a total
estimated cost of $10 billion. After Congress whittled down the Unitary Plan to $27
million only one such tunnel was constructed--at Ames. Not only was the tunnel
itself an engineering masterwork--with three tunnels operating integrated to make
the most efficient use of drive motors and researchers' time--but the tunnel
supported much of the key work that led America into the space age.
By 1957, international pressures, the arms race, and the orbit of Sputnik again
forced change in the administrative structure of Ames. On July 29, 1958, the
National Aeronautics and Space Act was signed. On October 1, 1958, the National
Aeronautics and Space Administration was born, it absorbed the NACA, and Ames became
a part of America's space program.
Scope and Content
This finding aid describes records that are housed at the National Archives and
Records Administration (NARA) Pacific Region facility in San Bruno, California.
Although the records belong to the National Archives, San Bruno, as the regional
repository for permanent archival records of Federal agencies in northern
California, this finding aid was authored to the Web by staff of the NASA Ames
History Project (
http://history.arc.nasa.gov ).
Researchers must contact NARA at (650) 238-3500 before using these records. Because
they are unprocessed, it takes substantially longer to make them available in the
NARA reading room. NARA kept these records in the same boxes and folders in which
they arrived from Ames, between 1953 and 1975. When Ames officials transferred these
records to the custody of NARA, they described the records in standard U.S.
Government transmittal forms (SF135 and SF258). This finding aid largely duplicates
the information on those standard forms. In some places, staff of the NASA Ames
History Project enhanced the folder descriptions. In other places, the file
descriptions are completely new.
NARA RESERVES THE RIGHT TO DISPOSE OF NON-PERMANENT RECORDS AT THE TIME OF PHYSICAL
PROCESSING OF THE RECORDS. That is, NARA still needs to fully implement the
retention schedule for these records, and process them according to archival
standards. As this happens, portions of this finding aid may become outdated or
irrelevant.
This collection both continues and complements a processed collection of NACA records
at NARA San Bruno (
RG255.4.1: Inventory of the National
Advisory Committee on Aeronautics, Ames Aeronautical Laboratory, Moffett Field,
CA,1939-1957
). Both sets of records were created at Ames, compiled by
the Ames Central Files Branch. The processed set of records were most likely closed
out in October 1958, when NACA facilities were absorbed in the the newly-established
NASA. This unprocessed collection, however, also includes a great many records
generated before October 1958, mostly pertaining to on-going projects that continued
under the new Administration. Ames' transformation into a NASA facility was gradual,
as a result of many historical factors. The same basic science projects continued,
using the same facilities, and under the same staff and director (Smith DeFrance).
X-15 research is one example of work that spanned the needs of the two agencies. Not
until the mid-1960s did Ames have more in common with the new NASA facilities than
with the old NACA facilities.
Thus, these two collections do not divide cleanly in October 1958. While this
unprocessed collection contains several headings pertinent only to Ames' role within
NASA--space capsule design, supersonic transport, Apollo missions, and life sciences
projects--researchers should always check the finding aids for both collections.

Common Abbreviations in the Ames Records
1. Branch Codes used by the Ames Report Unit
The Report Unit was the office at Ames that compiled and published technical
reports. These reports were written by researchers working in the technical
branches at Ames. These branches were identified by a two-letter code which
often appear in the file headings for Report Unit records, as well as in the
Central File records.
The two letter code mimics the organization chart at Ames. For example, every
branch within the Aeronautics Division began with the letter A. The second
letter identified the specific branch. The branches were usually defined as a
group working with a specific tool, like a wind tunnel. More recently, the
branch codes can be found in the Ames telephone directories. For the 1950s,
these branch codes were used.

2. NACA and NASA Report Abbreviations
The basic product of all NACA work, and to a lesser extent NASA work, was the
technical report. Thus, RG255.4 contains a great many reports or draft reports,
primarily in the Report Unit series but also interfiled in the Central File
series. All reports were published by the Government Printing Office, and some
were reprinted in scientific journals, though not all were given broad public
distribution.
Each report is identified by an alpha-numeric code. The suffix is a number
assigned chronologically. The prefix is a letter code (shown below) that
identifies the type of report it is, and these categories have changed several
times over NACA and NASA history. For a complete description of the report
generation process see: Alex Roland,
Model Research: The
National Advisory Committee for Aeronautics, 1915-1958
(NASA
SP-4103, 1985) especially volume II, Appendix G "Reports." Generally, advance
reports, notes, and memorandum present partial or preliminary results of a
research project and are data-rich but text-light. These are intended to
expedite the flow of information to NACA customers. Reports are the more formal
presentation of ideas, hypotheses, and supporting data.
The report-related files in RG255.4 only occasionally hold the final published
reports. Mostly they contain raw research data, drawings or photographs, draft
versions, peer reviews, distribution lists, and correspondence with the printing
office. Thus, researchers can always start their research into NACA reports more
efficiently by finding the published report elsewhere. Reports can be found on
microfiche at most federal government depository libraries (to locate the one
nearest you point your browser to
http://www.access.gpo.gov/su_docs/libpro.html ). NASA's technical
report server (RECONselect) allows users to search NASA and NACA publications by
author, title, report name, or subject heading, and the Digidocs system allows
readers to download digitized versions of select NACA reports. To access the
technical report server point your browser to:
http://www.sti.nasa.gov/RECONselect.html . Reports can also be
found at many engineering libraries or NASA Center libraries.
