... Heracles Triplane and Aerospace Systems . The key characteristics of two-stage aerospace systems are determined according to speed and carrying capacity of the aircraft-carrier used . ... So the SPIRAL system hypersonic carrier was expected to launch the second stage by weight 63 tons at a speed corresponding to 6M; whereas launching weight of the MAKS system orbital stage with the use of the An-225 MRIYA heavy subsonic aircraft reaches 275 tons, and the HERACLES aircraft - 450 tons. ...

... Phys. (U.S.S.R. ) 42, 1416-1418 (May, 1962) A series of size effects , which are determined by the relationships between the size of electron orbits and the size of a metallic sample, can be observed when a sample having a long fre e path is placed in a constant magnetic field. ... When the field is increased the radius of the electron orbit decreases, and the numbe r of return s of the electron throug h the skin layer durin g the fre e path time increases. ... The sample had a thickness of 0.54 mm ...
