Gerald Bull
Gerald Vincent Bull (March 9, 1928 – March 22, 1990) was a Canadian engineer who developed long-range artillery. He moved from project to project in his quest to economically launch a satellite using a huge artillery piece, to which end he designed the Project Babylon "supergun" for the Iraqi government

Avro Arrow
The Avro Canada CF-105 Arrow, often known simply as the Avro Arrow, was a delta-winged interceptor aircraft designed and built by Avro Canada. The Arrow is considered to have been an advanced technical and aerodynamic achievement for the Canadian aviation industry. The CF-105 (Mark 2) held the promise of near-Mach 2 speeds at altitudes of 50,000 feet (15,000 m) and was intended to serve as the Royal Canadian Air Force's (RCAF) primary interceptor in the 1960s and beyond. Canada tried to sell the Arrow to the U.S. and Britain, but no agreements were concluded. The aircraft industry in both countries was considered a national interest and the purchase of foreign designs was rare. The Arrow was the culmination of a series of design studies begun in 1953 examining improved versions of the Avro Canada CF-100 Canuck. After considerable study, the RCAF selected a dramatically more powerful design, and serious development began in March 1955

Laval University
Université Laval (English: Laval University) is a French-language, public research university in Quebec City"> Quebec City, Quebec, Canada. The University was founded by royal charter issued by Queen Victoria in 1852, with roots in the founding of the Séminaire de Québec in 1663 by François de Montmorency-Laval, making it the oldest centre of higher education in Canada and the first North American institution to offer higher education in French

Supersonic Wind Tunnel
A supersonic wind tunnel is a wind tunnel that produces supersonic speeds (1.2<M<5) The Mach number and flow are determined by the nozzle geometry. The Reynolds number is varied by changing the density level (pressure in the settling chamber). Therefore, a high pressure ratio is required (for a supersonic regime at M=4, this ratio is of the order of 10). Apart from that, condensation of moisture or even gas liquefaction can occur if the static temperature becomes cold enough. This means that a supersonic wind tunnel usually needs a drying or a pre-heating facility

Royal Canadian Air Force
The Royal Canadian Air Force (RCAF; French: Aviation royale canadienne, ARC) is the air force of Canada. Its role is to "provide the Canadian Forces with relevant, responsive and effective airpower". The RCAF is one of three environmental commands within the unified Canadian Armed Forces. As of 2013, operating 258 manned aircraft and 9 unmanned aerial vehicles, the Royal Canadian Air Force consists of 14,500 Regular Force and 2,600 Primary Reserve personnel, supported by 2,500 civilians. Lieutenant-General Michael J. Hood is the current Commander of the Royal Canadian Air Force and Chief of the Air Force Staff. The Royal Canadian Air Force is responsible for all aircraft operations of the Canadian Forces, enforcing the security of Canada's airspace and providing aircraft to support the missions of the Royal Canadian Navy and the Canadian Army

Supersonic
Supersonic travel is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.23. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect

Ordnance QF 17-pounder
The Ordnance Quick-Firing 17-pounder (or just 17-pdr) was a 76.2 mm (3 inch) gun developed by the United Kingdom during World War II. It was used as an anti-tank gun on its own carriage, as well as equipping a number of British tanks. It was the most effective anti-tank gun of the war fielded by the Western Allies (that is, excluding the Soviet Union). Used with the APDS shot, it was capable of defeating all but the thickest armour on German tanks. It was used to 'up-gun' some foreign-built vehicles in British service, notably to produce the Sherman Firefly variant of the US M4 Sherman tank, giving British tank units the ability to hold their own against their German counterparts. In the anti-tank role, it was replaced after the war by the 120 mm BAT recoilless rifle

Sabots
A sabot (UK and Int.: /sæˈb/, /ˈsæb/, US: /ˈsb/) is a structural device used in firearm or cannon ammunition to keep a sub-caliber flight projectile, such as a relatively small bullet or arrow-type projectile, in the center of the barrel when fired, if the bullet has a significantly smaller diameter than the bore diameter of the weapon used. The sabot component in projectile design is more than simply the relatively thin, tough and deformable seal known as a driving band or obturation ring needed to trap propellant gases behind a projectile, and also keep the projectile centered in the barrel, when the outer shell of the projectile is only slightly smaller in diameter than the caliber of the barrel
