Скачать или смотреть Dassault Mirage III prototype and pre-production (1955-1960)

The Dassault MD.550 Delta was powered by a pair of 9.61 kN Armstrong Siddeley MD30R Viper afterburning turbojet engines (built under licence by Dassault) with a SEPR-built 66 liquid-fuel rocket engine, capable of providing boost thrust of 4.7 kN.
On 25 June 1954, the first prototype of the MD.550 Delta, without afterburning engines or rocket motor and with an unusually large vertical stabilizer, conducted its maiden flight.
In late 1954, the prototype attained a recorded speed of Mach 1.3 in level flight without rocket assistance, as well as reaching Mach 1.6 when using the rocket motor.
The small size of the Mirage I restricted its armament to a single air-to-air missile, and it was decided during flight trials that the aircraft was too small for the carriage of a useful armament.

The Mirage III 001 incorporated various new design principles, such as the transonic area rule concept, where changes to an aircraft's cross-section were made as gradual as possible, resulting in the famous "wasp waist" configuration of many supersonic fighters.
It powered by the newly developed Snecma Atar afterburning turbojet engine, capable of generating up to 43.2 kN (9,700 lbf) of thrust with a provision for a booster rocket engine.
On 17 November 1956, the prototype Mirage III perform its first flight.
During its 10th flight, it was recorded as having attained a speed of Mach 1.52

The success of the Mirage III prototype resulted in an order for 10 pre-production Mirage IIIA fighters.
The Mirage IIIA were almost 2 meters longer than the Mirage III prototype, had an enlarged wing of 17.3 per cent greater area, a chord reduced to 4.5 per cent, and an Atar 09B turbojet capable of generating afterburning thrust of up to 58.9 kN (13,200 lbf).
In May 1958, the first Mirage IIIA conducted its first flight. In October of that year, this aircraft achieved a top speed of Mach 2.2 during one of its test flights, thus becoming the first European aircraft to exceed Mach 2 in level flight.
