The Delta used the same wing as the Gamma had split flaps and a non-retractable undercarriage like its predecessors | Northrop Delta | CV183 | Canadian Vickers Ltd. | Canada | Québec | Montréal | 1938 | before | 1 | In 1935 when the RCAF wanted a high performance photographic aircraft it considered the Northrop Gamma but instead settled on Northrop's transport version of the same aircraft the Northrop Delta. Canadian Vickers was commissioned to build an initial four aircraft under license and these were the first all-metal stressed-skin aircraft to be built in Canada. The Delta used the same wing as the Gamma had split flaps and a non-retractable undercarriage like its predecessors. The larger fuselage accommodated up to eight passengers. For RCAF use the design was modified to accept three Fairchild A-3 cameras at the rear of the cabin. The cabin floor was strengthened to accept freight loads and a large upward opening freight door was installed on the port side. Two Deltas were armed with a defensive machine gun fitted in an open hatch in the roof. Protection from the slipstream was provided by a plexiglas fairing. This particular installation was not very satisfactory causing buffeting and a marked decrease in performance. | Aviation | Aircraft | metal->aluminum;metal->steel;resin->rubber | 9.8 M | 14.6 M | http://source.techno-science.ca/artifacts-artefacts/images/1966.0069.001.aa.cs.png | http://source.techno-science.ca/artifacts-artefacts/images/1966.0069.001.aa.cs.thumb.png |
