Velvet Glove
The Velvet Glove was a short-range semi-active radar homing air-to-air missile designed by CARDE (today DRDC Valcartier) and produced by Canadair starting in 1953. 131 Velvet Gloves had been completed when the program was terminated in 1956, officially because of concerns about its ability to be launched at supersonic speeds from the Avro Arrow then under design, but also from the design being overtaken by developments in the United States. Design and construction Small scale work on what would become the Velvet Glove started in 1948 at CARDE, and by 1951 the plans were advanced enough to put forth the design as armament on the Avro CF-100 "Canuck" fighter that was then entering service with the Royal Canadian Air Force (RCAF). Canadair was selected as the manufacturer, and Westinghouse was commissioned to build the radar guidance unit. The final missile design was about long and just under a foot in diameter. It used four fins at the tail for steering, and was guided by a semi- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-to-air Missile
The newest and the oldest member of Rafael's Python family of AAM for comparisons, Python-5 (displayed lower-front) and Shafrir-1 (upper-back) An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors, usually solid fueled but sometimes liquid fueled. Ramjet engines, as used on the Meteor, are emerging as propulsion that will enable future medium-range missiles to maintain higher average speed across their engagement envelope. Air-to-air missiles are broadly put in two groups. Those designed to engage opposing aircraft at ranges of less than 16 km are known as short-range or "within visual range" missiles (SRAAMs or WVRAAMs) and are sometimes called "dogfight" missiles because they are designed to optimize their agility rather than range. Most use infrared guidance and are called heat-seeking missiles. In contrast, medium- or long-range missiles (MRAAMs or L ...

Schlieren Photography
Schlieren photography is a process for photographing fluid flow. Invented by the German physicist August Toepler in 1864 to study supersonic motion, it is widely used in aeronautical engineering to photograph the flow of air around objects. Classical optical system The classical implementation of an optical schlieren system uses light from a single collimated source shining on, or from behind, a target object. Variations in refractive index caused by density gradients in the fluid distort the collimated light beam. This distortion creates a spatial variation in the intensity of the light, which can be visualised directly with a shadowgraph system. Classical schlieren imaging systems appear in two configurations, using either one or two mirrors. In each case, a transparent object is illuminated with collimated or nearly-collimated light. Rays that are not deflected by the object proceed to their focal point, where they are blocked by a knife edge. Rays that are deflected by t ...

National Air Force Museum Of Canada
The National Air Force Museum of Canada is an aviation museum dedicated to preserving the history of the Royal Canadian Air Force (RCAF) and is located on the west side of CFB Trenton in Trenton, Ontario. The museum is a permanent archive which collects, preserves and displays Royal Canadian Air Force (RCAF) memorabilia, photographs, paintings and documents as a lasting tribute and memorial to all the men and women who served in the RCAF and its predecessor organizations. History The RCAF Memorial Library and Museum opened on 1 April 1984 – the 60th anniversary of the establishment of the Royal Canadian Air Force – in the CFB Trenton Recreation Center. However, the museum quickly outgrew the location and moved to the base's former curling club exactly 10 years later in 1994. With the acquisition of a Handley Page Halifax restoration project in 1995, the museum was again short on space. So from 2004 to 2005 the museum constructed a purpose built Main Exhibition Hall.

United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIM-4 Falcon
The Hughes AIM-4 Falcon was the first operational guided air-to-air missile of the United States Air Force. Development began in 1946; the weapon was first tested in 1949. The missile entered service with the USAF in 1956. Produced in both heat-seeking and radar-guided versions, the missile served during the Vietnam War with USAF McDonnell Douglas F-4 Phantom II units. Designed to shoot down slow bombers with limited maneuverability, it was ineffective against maneuverable fighters over Vietnam. Lacking proximity fusing, the missile would only detonate if a direct hit was scored. Only five kills were recorded. With the AIM-4's poor kill record rendering the F-4 ineffective at air-to-air combat, the fighters were modified to carry the USN-designed AIM-9 Sidewinder missile instead, which was already carried on USN and USMC F-4 Phantom II and F-8 Crusader jet fighters. The Sidewinder was much more effective and improved versions continue to serve the armed forces of the United Stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Of Commons Of Canada
The House of Commons of Canada (french: Chambre des communes du Canada) is the lower house of the Parliament of Canada. Together with the Crown and the Senate of Canada, they comprise the bicameral legislature of Canada. The House of Commons is a democratically elected body whose members are known as members of Parliament (MPs). There have been 338 MPs since the most recent electoral district redistribution for the 2015 federal election, which saw the addition of 30 seats. Members are elected by simple plurality ("first-past-the-post" system) in each of the country's electoral districts, which are colloquially known as ''ridings''. MPs may hold office until Parliament is dissolved and serve for constitutionally limited terms of up to five years after an election. Historically, however, terms have ended before their expiry and the sitting government has typically dissolved parliament within four years of an election according to a long-standing convention. In any case, an ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AIM-7 Sparrow
The AIM-7 Sparrow (Air Intercept Missile) is an American, medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, and United States Marine Corps, as well as other various air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM. The early Sparrow was intended primarily for use against larger targets, especially bombers and had numerous operational limitations in other uses. Against smaller targets, the need to receive a strong reflected radar signal made achieving lock-on at the missile's effective range difficult. As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat, the enemy fighter would often approa ...

Trenton, Ontario
Trenton (2001 population 16,770) is a large unincorporated community in Central Ontario in the municipality of Quinte West, Ontario, Canada. Located on the Bay of Quinte, it is the starting point for the Trent-Severn Waterway, which continues northwest to Peterborough and eventually Port Severn on Georgian Bay. History The Trenton area is part of the traditional area of the Mississauga and other Indigenous First Nations. The first known expedition by Europeans in the area was one by French explorer Samuel de Champlain, which followed the Trent passing through Trenton in 1615. The Trent River is known to the Mississauga as ''Sangichiwigewonk'', or 'fast flowing.' Settlers gave it the name 'Trent', after the River Trent in England. The area around the mouth of the Trent River was first settled by Europeans in the 1780s, after the area was ceded to the British in 1783 as part of the Crawford Purchase. United Empire Loyalists first settled in Trenton in 1792. First named Trent Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
