ADDITIONAL PICTURES & INFORMATION

As with several of the supersonic aircraft of the day, the Arrow, because of it's supersonic delta wing configuration, was subject to a high take-off and landing speed. Coupled with it's rather delicate and complex landing gear, this made for a difficult mix. There was one rear landing gear failure during testing. I would not consider this unusual or major, however, for this type of aircraft. The Arrow also sat at a very high angle of attack on the runway. This was also typical for aircraft of it's type. It's easy to look at today's aircraft and spot these difficulties with the CF-105. They did not have much experience with supersonic flight at that time, let alone variable geometry or computer technology. Remember also, that this was at the height of the cold war. Technical information was not shared easily even between allies

The Iroquois Engine Requirements

This engine had to power the Arrow to Mach 1.5 at 50,000 feet. This would require the engine to produce 19,000 pounds of thrust without afterburner and 26,000 pounds of thrust with the afterburner. In the earliest stages of development the engine produced 19,350 pounds of thrust without afterburner and 25,600 pounds of thrust with the afterburner. Design This kind of performance was possible because of a revolutionary design and some of the earliest use of titanium. The titanium allowed the engine to weigh much less than any other available at the time. Besides the obvious benefit of weight savings the low weight also allowed the engine to spool up quickly because of less spinning mass. Weight saving was important because the Arrow is such a large aircraft.

Janusz Zurakowski Birthdate: September 12, 1914 Birth Place: Ryzawka, Russia Year Inducted: 1973

"The dedication of his aeronautical skills to the successful flight testing of Canada's first supersonic aircraft resulted in outstanding benefit to Canadian aviation." Janusz Zurakowski attended high school in Poland where he learned to fly gliders and later joined the Polish Air Force in 1934. At the outbreak of WWII he was an instructor at the Central Flying School and later transferred to Nos. 234 and 609 Squadrons, RAF. In 1945 he was posted to the Aircraft and Armament Experimental Establishment where he tested Britain's first jet fighter, the Vampire. During his career Zurakowski also demonstrated a new air stunt called the "Zurabatic Cartwheel" and established a new air speed record in 1950 between London-Copenhagen-London. He emigrated to Canada in 1952 to join Avro Aircraft Limited at Toronto as chief development pilot. In this position, he test flew the CF-100 aircraft and completed the first supersonic flight of the Avro Arrow.
