"The Dassault fighter-interceptor project MD-750.
The first drafts of the French fighter aircraft, capable of speeds of M = 3.0, date back to the year 1958. In this year the Nord Aviation companies and Dassault were presented preliminary designs fighter Super Griffon and Mirage VIA (the latter was supposed to have a take-off mass 13 tons and power plant as the Super Atar TURBOJET ENGINE with a thrust of 9 tons). The program was closed and then restarted only in 1964 a year after the appearance of fighter-interceptor MiG-25 and the razvedchika SR-71.
In February 1964 the year Pierre Mesmerom (Pierre Mesmer)-Defence Minister under President de Gaulle-Centre perspective forecasting and evaluation (CPE-Centre de Prospective et d'Évaluation). The Centre is headed by Hugo de l'Jestual (Hughes de l'Estoile), which May 25, 1965 year drew attention to the research
"aircraft, capable of flying at high Mach numbers.
It appeared that the aircraft will be commissioned in the year 1980 and will serve as the interceptor, long-range reconnaissance aircraft and to serve as a strategic tool to air attack. In August 1967 the year CPE became BPE (Bureau [Bureau] has replaced Centre [Centre]). Royal Air Force operated soon, but officers quickly pointed out that the draft is fairly vague and that it is easier to create a rocket capable of develop the same speed. In fact, aircraft, capable of developing speeds of M = 3.0. 4.0, interest to perform police duties in the sky in case of trehmahovyh civilian aircraft.
November 22, 1965 year promising aircraft Bureau (BPA-Bureau Prospective Air) French air force gave a favourable opinion, clearly indicating that this should be the study without issuing a Passport program (fiche-programme). The result was the announcement of December 14, 1965 year leadership of CPE competition attended by the company Dassault Breguet Aviation, Nord and Sud Aviation. In May 1966 year, Dassault and Sud Aviation had submitted their proposals.
The company Matra and Thomson were invited to develop missiles and radar. The company Thomson unveiled a fixed antenna with electronic scanning (this type of antennas now installed on Rafale fighters), and research the company Matra has served as the basis for creating Super 530.
Ten were considered variants of the powerplant, including sharing of turbojet and highly integrated air-jet engines; of these ten eight options were offered by SNECMA. One version of the project was developed on the basis of installed on SR-71 J58 engine. Other versions of the draft were based on the application engine TF306: this was a TURBOJET ENGINE development TF30, installed on experimental airplanes Mirage F2 and Mirage G and gave the company SNECMA experience works on creation M53-a successor to the original engine. One of the options of the project had 43-LZ1 have two motors M53.
If the company Sud Aviation quickly eliminated from the game, then Dassault vice versa has begun to develop a large number of preliminary draft aircraft that can reach speeds of M = 4.0, and the first proposals were submitted by October 19, 1966 year. It was the first time French engineers used computers to calculate flight trajectories and characteristics of the aircraft.
The Dassault company studies of thermal resistance design, and it was suggested that the use of steel and titanium using cell fillers, panels which were tested in termoustanovke.
However, projects the company Dassault encountered distrust and skepticism on the part of the air force, whose officials have expressed their doubts in June 1967 year. Construction of a fighter with a top speed of M = 4.0 in terms of works on creation of structural materials, aircraft engines and its takeoff weight (one of the projects-MZ1-46Q-exceed 40 tons) went beyond the capacity of the industrial the capacity of France. In addition, hostile aircraft-before fighter, flying at a speed of M = 3.0, his catch-invaded deep into France would be at 400 km. Therefore, there was little information projects-in fact they were both would be classified. Just recognized that, at least on paper, there are studies on this topic.
After done in 1967-68 years works Dassault was awarded 5 million francs on more specific and less ambitious program called SAME (Système Avion Mach Élevé): issue with speed M = 4.0 no longer stood, was chosen the range M = 2.5- 3.0 or M = 3.0-3.5.
February 19, 1969 year company Dassault twin-engine aircraft project was presented with a triangular wing, receiving the designation MD-750. Maximum speed of the aircraft was supposed to be M = 3.5 and time-to-height 16000 meters was supposed to be 5-6 minutes; In addition, it was planned that at the speed of 3.2 M = aircraft able to fly 10 minutes.
It seems like it is in this context that in June 1969 year in the magazine "Aviation Magazine painted were represented by Alan Ratino (Alain Ratineau) schema MD-750 in three projections. Any comments to diagrams. In the same year, during the same year, the air show in Le Bourget airplane model was presented at the stand of the company Dassault. Air plane immediately appropriated the designation "Super Mirage 6000" and "Mega Mirage.
The aircraft was supposed to be for fighter-interceptor, which would be similar to the Mirage IV bomber driving dimensions. Also MD-fighter-interceptor 750 should be flexible (two engines M-53) by plane with deltavidnym wing and tail feathers development.
MD-750 was supposed to be located in front of the air intake front fuselage (nose and cockpit) with the classical rectangular cross-section for the company. This similarity of planes ended. Landing gear had to be very large and, most likely, under the wing could pass not bending.
Two air intake should have a rectangular cross-section and remind the air intakes of the MiG-25; the upper part of the inlet was to begin immediately after the cabin and go down at an angle is 20°.
The main chassis (one wheel on each rack) were supposed to be under the wing and consoles, veering to the side of the fuselage, retract into niches, located in the wing and fuselage. Part of the niches of the main Struts, which were supposed to retract the wheels had to be placed at the bottom of the fuselage. When you release the landing gear of the niches the past had closed shutters installed on the fuselage on both sides of them. Front chassis (must also have one wheel) was to get out ahead and be placed under the fuselage at the level of the inlet.
The windshield was supposed to be static and consist of two separate transparent plates separated by a longitudinal arch. Movable canopy part should have been able to swivel its back and drift back up. She also was to consist of two separate elements, separated by a longitudinal arch. In General, a cockpit of the pilot was supposed to resemble the Lantern Canadian skilled fighter-interceptor CF-105.
Under the fuselage had to be placed two fairly large keel; they were supposed to start the main uprights chassis and reach for the rear fuselage gradually decreasing in altitude.
The aircraft was to be equipped with three air brakes. Two brakes had to be positioned on the upper part of the fuselage near the base of the keel, and third brake-in the lower part of the fuselage between the two keels.
However, the project still had little information, and he likely could be advertising the company's progress. As will be discussed further the question of the construction of this aircraft never seriously considered; you did not intend to produce neither prototype nor experimental aircraft.
In the year 1970, the program was deemed too ambitious, and instead was recommended by permitted the elaboration of ACF fighter with take-off weight 16 tons and a maximum speed of M = 2.5. In the framework of this programme was to be built multipurpose Mirage G8, which was to be used as a flying laboratory. Construction for ten years 170 fighter jets capable of flying with the speed of the M = 3, was estimated at 20 billion francs in the year 1969, prices that were up to four times more expensive than had similar effectiveness of the PVO air defense systems. In the SAME year 1971 was closed, despite the fact that Mirage G8 was able to accelerate up to speed (M) = 2.34.
In conclusion, the SAME program was more than an exercise for Design Bureau company Dassault: it showed the futility of seeking high-speed aircraft and helped to define the limits of the industrial potential of the country. Efforts were diverted to create missiles and decked aircraft. However, thanks to this program, SNECMA M53 engines were created, rocket Super 530 d and modern French radars.
