American naval officer and mechanical engineer

William Frederick Durand (March 5, 1859 – August 9, 1958) was a United States naval officer and pioneer mechanical engineer. He contributed significantly to the development of aircraft propellers. He was the first civilian chair of the National Advisory Committee for Aeronautics, the forerunner of NASA. A native of Connecticut, he was a member of the first graduating class of Birmingham High School in Derby, Connecticut (now Derby High School) in 1877. He graduated second in his class at the United States Naval Academy at Annapolis and received his Ph. D. from Lafayette College. He went on to teach at the Michigan State College, Cornell University and Stanford University, teaching that school's first course in aeronautics, the second offered by any school in the country (the first was offered by the Massachusetts Institute of Technology). He helped rebuild Stanford after the 1906 earthquake, and the department of Aeronautical and Astronautical Engineering building bears his name. A memorial there reads: "His first professional assignment in 1880 was on the Tennessee, a full rigged wooden ship with auxiliary steam power. His last, 1942–46 was as chairman of the National Aeronautical Commission for the development of jet propulsion for aircraft." He died in 1958 at the age of 99.

While in Worcester Durand was approached by a member of the board of trustees of Michigan State College. Michigan State was looking for someone to create and head a mechanical engineering program. Durand accepted the position and resigned his commission with the US Navy effective 15 September 1887. Durand worked at Michigan State in Lansing, Michigan, for four years, creating the Department of Mechanical Engineering. In 1893 Durand published a paper mathematically describing a radial planimeter for averaging values plotted in polar coordinates. Originally a radial planimeter was of academic interest only, but ten years later clock driven recording instruments started being used. Durand created working device based on his theory. He patented the device and received royalties from a scientific instrument company making the devices until the patent expired. Durand was appointed head of the Engineering Division. Both the NACA and the NRC had offices in the Munsey Trust Building in Washington separated by two floors. Durand climbed stairs or rode the elevator several times a day between the two. On September 11, 1925, Durand learned over the radio that Coolidge had appointed him to the board. The board was tasked to study aeronautics in relation to national defense and advise the president on policy to develop aircraft in time of war. The board was composed of Morrow as chairman, U. S. Judge Arthur C. Denison as vice chairman, Durand as secretary, Hiram Bingham, James S. Parker, Carl Vinson, Maj. Gen. James G. Harbord (ret. ), Rear Admiral Frank F. Fletcher (ret. ), and Howard E. Coffin. The first meeting of the board was held at the White House where Durand was chosen to be secretary of the board. After weeks of meetings receiving expert testimony and conferring the board submitted a report to the President recommending a near term development plan for military and naval aircraft. The report further recommended the creation of the offices of Assistant Secretary for Military and for Naval aircraft within the War and Navy Departments. The final volume was published in 1936. Leslie tested seven propellers with a VE 7. Durand's wind tunnel model showed similar efficiency to Leslie's measurements, but lagged by 6% to 10% in thrust developed and power absorbed.

In 1927 Durand became a member of a board of advisers to the Secretary of Work of the United States Department of the Interior. The board was tasked to survey the Colorado River to find solutions to annual flooding, silting, the development of hydroelectric power, and water usage for irrigation and by cities such as Los Angeles, California. Science Advisory Board Chairman Karl T. Compton appointed a Special Committee on Airships at the request of Secretary of the Navy Claude Swanson. Members of the committee were Robert A. Millikan and Theodore von Kármán of Caltech, William Hovgaard of M. I. T., Durand and Stephen Timoshenko of Stanford, Frank B. Jewett of Bell Telephone Laboratories, and Charles F. Kettering of General Motors. Durand was the chairman.

Upon request of the United States Department of the Navy, the National Academy of Sciences established a committee chaired by Durand to investigate anti rolling devices on ships. The ability to stabilize a ship such as an aircraft carrier would be extremely useful during the landing of airplanes. The committee established an experimental laboratory at the Brooklyn Navy Yard. A full scale version of the system was tested in Hamilton but exhibited control stability problems. Very promising results were beginning to appear when the outbreak of the Second World War interrupted further development as the Hamilton was called to active duty and the 5 ton model was put into storage.

In March 1941 Chairman of the NACA Vannevar Bush asked the then 82 year old Durand to head a committee to study and develop jet propulsion for aircraft. The committee was composed of members from General Electric, Westinghouse, and Allis Chalmers. The committee agreed early that the three companies would work separately developing jet engines to promote diversity in design. Chief of the Air Corp Henry H. Arnold obtained a Whittle jet engine from England which was turned over to the gas turbine division of GE in Lynn, Massachusetts, for test and copy. General Electric developed this into the J31. Durand witnessed a static test of the engine in Lynn, Massachusetts on July 13, 1942, alongside Sanford A. Moss, the engineer Durand had requested from General Electric for the development of turbosuperchargers during World War I. Moss had retired from GE but worked as a consultant on the jet engine. Durand and Moss spoke to each other of the early development of the turbosupercharger as the manager of the facility recorded their conversation. On October 2, 1941, Durand witnessed the first official flight of the J31 equipped Bell P 59 Airacomet at Muroc Army Air Field (today, Edwards Air Force Base). Westinghouse developed the J30 engine from this effort. Durand led the jet engine effort from April 2, 1941, to July 7, 1945, at which time Durand was 86 years old

Also beginning in early spring 1941 Durand chaired the Engineering Division of the National Research Council. Durand split his work days, mornings at the NACA, afternoons at the NRC. Durand was greatly helped by the NRC Division Executive Secretary William H. Kenerson of Brown University.
