The laboratories of the National Research Coun- cil (above) are located at Montreal Road, Ottawa. Top right, elevator ad- justment on delta half- model in 30in x 16in supersonic tunnel. Right, the N.R.C. high- speed aerodynamics laboratory. The two Horton spheres provide a common vacuum for the two main tunnels. Progress in Research AT TWO CANADIAN ESTABLISHMENTS THE pattern of Canada's aeronautical research is not a simpleone; nor is it static. Developed over the years in parallelwith the expansion of industry and the Services, the frame- work is now being further modified to meet the present-day needsof a country which is devoting increasingly more brainpower to selected aspects of basic research, as well as to applied problemsof development. The aeronautical laboratories of the National Research Councilat Montreal Road, Ottawa, have for many years been the centre of Canadian aeronautical research. A more recent unit on the sceneis the National Aeronautical Establishment, located at Uplands Airport, Ottawa, which was formed only five years ago and is atpresent operated by the N.R.C. The work of the two establishments is very closely integratedindeed, with wind-tunnel and laboratory work being carried out at N.R.C. and flight testing (and associated work) at the N.A.E. Thepresent stage is a transitional one, however, and with the building up of tunnel and other facilities at Uplands this establishment willbe taken over by the Defence Research Board (the research organ- ization of the Department of National Defence), and the N.A.E.emphasis will be placed on research and development for military and defence purposes. Up to the present time the N.R.C. hasperformed both fundamental research and ad hoc investigations into military applications; when the National Aeronautical Estab-lishment is fully developed, N.R.C. will revert largely to its role of basic study and experiment. On a recent visit to Ottawa, Flight was shown around the twoestablishments by Dr. D. C. MacPhail, assistant director of the mechanical engineering division of the N.R.C. (Mr. J. H. Parkin,C.B.E., director of the division, is also director of the N.A.E.). At the Montreal Road laboratories, the aerodynamics section possessesfour main wind-tunnels, plus a pilot tunnel which is a l/12th scale working model of a 5ft x 5ft supersonic tunnel which has beendesigned at N.R.C. for the N.A.E. at Uplands. The low-speed laboratory contains a conventional 10ft x 6ft tunnel capable of airspeeds up to 300 m.p.h., and a 15ft diameter spinning tunnel. Major high-speed facilities comprise a 16in x 30in intermittenttransonic tunnel (Mach 0.5 to 2.0) with a ventilated working- section; and a lOin x lOin supersonic tunnel (up to Mach 3), alsoof the intermittent type. Other aeronautical facilities at the N.R.C. are seen in the thermo-dynamics and mechanics sections. The former contains a gas The 76/n x 30in high-speed tunnel at N.R.C. Mach number range is 0.5 to 2.0, slotted liners being used for subsonic and transonic testing.
