Avro Canada

Founded 1945 - Defunct 1962 - Location Toronto, Canada

In 1952, Avro Aircraft Ltd., a Canadian firm located at Malton near Toronto, began to develop a unique, supersonic fighter-bomber aircraft that could takeoff and land vertically, cruise at low altitudes on a cushion of air (also called ground effect) or accelerate to high speeds at higher altitudes.

The concept looked promising and the Canadian government agreed to fund the study. However, the contract expired before the study could be completed and the government abandoned the project as too costly.

Work had progressed far enough to interest the Americans.

In July 1954, the U. S. government awarded Avro two contracts worth nearly $2 million to continue the study, and Avro added another $2.5 million.

The program remained in Canada but was now owned and controlled by the United States. Avro had named it Project Y, but the U. S. Department of Defense labeled it Weapon System 606A.

In 1958, when the U. S. Army and Air Force took control of the project, they named the vehicle 'Avrocar' and designated it the VZ-9AV ('VZ,' experimental vertical flight; '9,' ninth concept proposal; and 'AV,' Avro). The Avro VZ-9AV Avrocar had fill some enormous shoes. The Army strategists looked for a subsonic, all-terrain reconnaissance and troop-transport vehicle, something rugged and adaptable that could replace light observation aircraft and helicopters.

They wanted a two-man craft that could perform the traditional roles of the cavalry: reconnaissance, counter-reconnaissance, pursuit, harassment and screening. In addition to its own airframe weight, the saucer had to carry 450 kg (1,000 lbs) including the crew.

It also had to hover in ground effect and at higher altitudes, and travel at speeds of about 48.3 kph (30 mph) for at least thirty minutes. In short, the Army wanted a flying jeep.

U. S. Air Force planners wanted something else.

They asked for a VTOL aircraft that could hover near the ground, beneath the coverage of enemy radar, and then rocket into the stratosphere at supersonic speeds. To satisfy both services, the Avrocar would require a huge performance envelope and rather naively, Avro engineers believed they could build a supersonic flying jeep. John Frost was chief project engineer for Weapon System 606A, the Avrocar. One of the oddest features of Frost's design was its shape.

The entire aircraft was a circular wing shaped much like the ubiquitous Frisbee.

From a distance, the gleaming aluminum Avrocar looked like the flying discs popularized in many Hollywood science-fiction movies of that era. Frost and his design team powered the aircraft with three gas-turbine engines and the combined exhaust from these power plants drove a "turborotor" mounted in the center of the vehicle. Turborotor thrust passed through a combination of annular nozzles and peripheral jets to generate lift and control forces. On paper, the design promised hovering takeoffs and landings and cruise speeds upwards of 322-483 kph (2-300 mph) at an altitude of 3,040 m (10,000 ft).

It was thought that eventually, the aircraft could attain supersonic speeds. A scale model of the aircraft was sent to Wright Field outside Dayton, Ohio, for testing. At first, the test results seemed to confirm Avro's calculations but further review of the data revealed a serious setback. The jet of air generated by the turborotor to cushion the aircraft near the ground grew increasingly unstable at altitudes of more than a few feet. The problem could be solved but it would reduce the craft's high-end performance.

The saucer would probably never fly supersonic. Despite this setback, the Americans decided to stick with the program and hoped that at least the Army's requirements for a subsonic aircraft could be met. In the fall of 1959 the first completed Avrocar prototype rolled out onto the taxiway apron at Malton.

Avro was already well advanced on a second prototype. Tests on the first vehicle began, using a special test rig to suspend the Avrocar in the air.

The results led to immediate modifications to the annular nozzles, a key element to the lift and propulsion of the aircraft. After reworking the nozzle, Avro packed up the Avrocar like an oversize dinner plate and shipped it to the National Aeronautics and Space Administration (NASA) Ames Research Center at Moffett Field, California. NASA had a wind tunnel at Moffett big enough to hold the VZ-9AV. Meanwhile, Avro finished the second prototype and began flight tests, using a safety tether, in September 1959. The first free flight occurred later that winter.
