On cause M-57 (Posted by: Michel Van ) agree, schematic they similar , more so that draft variant was plenty of ( radically differring between itself)
" Besides traditional strategic aviation systems, the Air Forces considered(counted) expedient to work low-level (250-600) intercontinental bombing system with jumping up in area of the purpose up to 16000-17000 m with a nuclear power-plant and armed by guided missiles with range of flight of 500-1000 km. Within the limits of these offers in ОКБ-23 under direction of L.L.Selyakova in July, 1959 the preliminary project of the strategic aviation system M-57, was has been prepared by the further development of the ideas incorporated in project М-56. Preliminary calculations spoke, that there is an opportunity to receive the plane with the area of a wing 400 м2 and mass feedback on fuel of 70,2 %.
Externally М-57 was similar to the project of bomber А-57 of R.L.Bartini. According to the project plane M-57 should was to be carried out under the scheme(plan) of " a flying wing » (there was a variant with PGO=tail-first). The settlement area of a triangular wing with a corner swept on a forward edge 75 ° in a final variant was defined(determined) in 400 м2 , settlement cruiser aerodynamic quality on a supersonic mode was within the limits of 5,9-6,2. The take-off weight reached(achieved) 250 tons, thus mass feedback on fuel reached(achieved) 72,0 %. The Power-plant should consist of six engines NK-11 (НК-15). Cruiser supersonic speed of flight М-57 should correspond(meet) М=3,6, and a ceiling above the purpose to reach(achieve) 26000 m. the Arms of the plane should consist of 2 rockets of type Х-22.
Was planned to begin letnye tests of the plane in 1963. As well as in case of with М-56, all works above the project have been stopped in the beginning of 60th years.
