This fonds consists of records relating to the life and career of aeronautical engineer William Kuzyk. Included here are textual records, photographic material, technical drawings, and cartographic material relating to scientific research mainly on (but not limited to) the C-102 Jetliner, the CF-100 Canuck, and the CF-105 Avro Arrow. These records document pioneering aeronautical engineering work that occurred in Canada during the 1940s and 1950s. More specifically, the fonds consists of: private notes; working papers; correspondence; A.V. Roe documents; and other documents/manuals relating to Kuzyk's work in the United States. The fonds includes: 4th year laboratory reports relating to aeronautical engineering from the University of Toronto; photographs of various technical aspects of the C102 Jetliner; Research notes on the C102 Jetliner project, including technical documentation such as test flight data and other information on performance (1949-1950); photographs of various technical aspects of C102 Jetliner, as well as additional photographs of the C102 Test Flight; copy of presentation by James Floyd, Project Designer, entitled The Avro C102 Jetliner (1950); draft technical documentation on target drones (1956); U.S. Airforce Aeronautical Planning Chart of Canada; cross-section drawing of fuselage, wing, and vertical tail section for prototype CF-105 Avro Arrow (1955); sketches, research notes, and other technical documentation on future models of the CF-105 Avro Arrow that would be developed - including a zero launch version, the application of ramjets to the airframe, as well as VTOL technology - to meet changing weapons and strategic context, such as the development of Inter-continental ballistic missiles (1957-59).
