To develop a single-rotor Mi-2 helicopter with two turboshaft engines, designed to replace Mi-1, launched in 1960, its First flight took place in September 1961 Serial production began in 1963 in Poland at the PZL Swidnik factory and lasted until 1992 Only built more than 5250 helicopters. Mi-2 can accommodate eight passengers or four stretcher patients and accompanying persons, and on an external sling carries a weight of 800 kg. On the basis of Mi-2 created more than 20 models, including military.
Mi-2
Single-rotor helicopter classical scheme of “Ansat” designed in KB Kazan helicopter plant. “Ansat” designed to carry up to nine passengers or 1300 kg of cargo (on external sling). The first flight of the prototype machine equipped with two turboshaft engines, “Pratt & Whitney/Klimov” РК206С, on 17 August 1999, and pre-production in December 2001, the Latter differed from its predecessor more spacious and streamlined form of the fuselage. It contains on-Board information control system flight information region (BISK). Vane steering and bearing (sleeve hingeless) rotor made of composite materials. Chassis — skid, but some modifications may be provided with wheeled supports.
On the drawing Board stood out the contours of a completely new fighter, interceptor unprecedented for that time qualities. He will not have to look for enemy bombers — a plane meteoric rise when they enter in the area of its action. A monstrous climb rate will enable an interceptor for a few seconds to attack enemy aircraft, leaving his pilots time maneuvering.
One of the most important tasks of fighter aircraft is to protect important areas, districts and objects on the territory of the country from air strikes. After the Second world war, the development of tactical flight characteristics of aircraft of a potential enemy greatly complicated the task of defense of the air borders of our country Location of U.S. military bases and their allies near the borders of the Soviet Union put the leadership of our country before the problem of protection from the threat of nuclear strikes on industrial sites and administrative centers, which until recently was considered a deep rear that the enemy at the most critical development of the fighting, It demanded significant expansion of the capabilities of the air defense Forces of the country increase their number to cover all important industrial regions, technical re-equipment of principally new types of weapons and military equipment.
Bomber-attack aircraft A-26 INVADER. If you ask aviation experts to name the most well-known plane-survivor, then some of them will remember a passenger DC-3 by Douglas, the other a transport Ju-52 Junkers, but others — about the legendary multi-purpose biplane Po-2 n N Polikarpov however, many wrongly forget about a medium bomber and attack aircraft Douglas A-26 Invader. Combat experience with the A-26 neither one of the planes of the US air force and made his first combat flight over Europe in September 1944, the aircraft remained in service for more than 25 years and flew combat missions during the Vietnam war until the early 1970s.
Projects and experienced first instances of jet aircraft with variable geometry wings appeared during the Second world war: in our country the project of this aircraft was developed V. V. Shevchenko and German company “Messerschmitt” even built experimental aircraft Р1101, which went to the Americans as a trophy. On the basis of the firm “bell” has created two pilot cars X-5, taking into account the requirements of the U.S. air force to the aircraft-attack aircraft. The first is constructed from X-5 first took to the air July 20, 1951 two years later, on may 19, 1953, in the United States flew another prototype aircraft with variable wing geometry — Jaguar XF10F-1, proposed by the Grumman American fleet. The tests confirmed a significant improvement in flight performance of the aircraft due to the wing using variable geometry, but the final results of flight tests were negative. And only eleven years later, on December 21, 1964, made the first flight of the aircraft with variable wing geometry XF-111A, designed by the firm “General dynamics”, accepted in 1967, the U.S. air force.
Since the profession of Aviator became popular, there was a need for a training aircraft They were needed for initial pilot training and for maintaining the necessary level of flight training of the personnel of combat units. Since the thirties of the XX century, a whole generation of Soviet pilots passed the initial training on a simple and reliable aircraft Po-2 For advanced training were used Yakovlevskaya UT-1 and UT-2. After the war, under the leadership of Alexander Yakovlev for this purpose has created the Yak-18 and Yak-11.
Antisubmarine warfare in the postwar years in the Soviet Union has always paid great attention. This goal was created not only surface ships, but also planes, it is Sufficient to recall the seaplane Be-unmanned, equipped with sonobuoys buoys, aeromagnetic, anti-submarine bombs and mines. With the advent of U.S. nuclear submarines armed with ballistic missiles “Polaris”, significantly increased the role of anti-submarine aircraft, which is now required not only discovery and destruction of submarines of the enemy, but also constant monitoring of their movements in the waters of the World ocean, the clarification of the anticipated areas of their combat duty Be-6, as established later, the amphibian be-12, were not suitable for patrolling in the remote areas of the oceans, and established on them equipment is not allowed to solve such a complex task.
Fights over Zaragoza and Wescoe. With the aim of weakening the Franco offensive on the Northern front, the Republican command has taken a series of diversionary strikes in the region of Zaragoza and Huesca.
In the late 1940’s-early 1950-ies in the Soviet Union developed several aircraft guided missile of class “air—air”. The actual results achieved by the designers who created the missile RS-1-U. Their work culminated in the adoption of the interceptor MiG-17ПФУ, armed with brand new weapons. (For more on this rocket in “M-K” No. 4, 2006).
