The improved design was referred to as the Avro Canada CF-105 Arrow, a name it certainly lived up to. With delta wings and a spearhead configuration, it flew like no other aircraft had at that time. Not only was it fast, but it was intense and deadly as well.
When the original design was improved upon, engineers focused on both strength and speed. Not only could the Avro Canada CF-105 Arrow reach heights above 50,000 feet, but it could fly at Mach 2 speeds or 1500 miles per hour.
The Soviets Pull Ahead
As the Canadians were working on the Clunk, the Soviets also had something new in the works. In 1952 the Royal Canadian Air Force received new intelligence that the Soviets were yet again one step ahead.
As it turned out, they were working on another aircraft, one that was rumored to be a highly destructive beast that could wipe the Canadians off the map in a matter of seconds. While the threat was real, the Soviets would need another seven years to get it ready. Canada still had some time to catch up, and they used it wisely.
New and Improved
The Avro CF-100 Canuck was ready for its very first launch flight in 1950. While some cheered the fighter jet’s first flight, others were watching the aircraft for ways it could be improved. What resulted from their analysis was the creation of an airplane like no other!
The Royal Canadian Air Force quickly put together a report detailing how the design of Avro CF-100 Canuck could be improved upon. It was titled RCAF's Final Report of the All-Weather Interceptor Requirements Team, also referred to as the Avro Arrow. Once the engineers had it in hand, they went straight to work!
Nine Prototypes
During this time, technology was nowhere near what it is today. They didn’t have computer simulation models to test their work. Instead, engineers had to create several prototypes of the models to be sure the aircraft functioned properly and was safe.
Between the years 1953 and 1957, nine prototypes of the Avro Arrow were generated. If they hadn’t taken these steps, it would have been impossible to foresee whether their improvements were successful. Each prototype was made with the proper specification, but they were scaled down in size to reduce costs.
Delta Wings
The Avro Arrow was named after its distinctive wing design, often referred to as delta wings. Today, delta wings are found on many small and medium-sized aircraft, but back it was an entirely new concept. Not only was it a more sleek design, but it had a purpose as well.
Aircraft engineers struggled for years to overcome the sound barrier. The production of the Avro Arrow led to the discovery of how to do this using the proper wing shape. Delta wings are unique as the wingspan reduces drag, allowing the plane to fly faster than the speed of sound.
