On the Internet, materials about Ivan Stepanovich Filimonenko and his work are often found. They are connected, as a rule, with two discoveries-inventions of the Soviet physicist: the installation of cold thermonuclear fusion and the magnetometer. If you still come across information about the first installation, then it is extremely little about the second development.
However, I come across an article titled "Flying Saucer. Made in the USSR ", which shows the drawings and design diagrams, however, rather indistinct (bad scan), authored (presumably) by Filimonenko himself. Of interest are also the comments of Ivan Stepanovich (presumably)
From the article it can be concluded that Filimonenko's magnetics consisted of two disks, and thrust was provided by the interaction of charged particles with a magnetic field. The design involved the rotation of the disks in opposite directions, and a certain contour of shielding from an external magnetic field. Two discs were needed to balance the interaction system.
The article also cited the following data: the disks were made of an insulator interspersed with metal particles, each of which interacted with the field: when moving perpendicular to the direction of the field, the interaction force is maximum and disappears with parallel movement. The shielding was designed to control this interaction so that only the maximum interaction force is used. It was as if it "fenced off" half of each disk from the external magnetic field.
According to Filimonenko's calculations, it turned out that the rotation of the disks was 1000 rpm. It was enough to get tens of tons of lift. Thus, the thrust was controlled by accelerating or decelerating the rotation of the discs.

But among researchers of Ivan Filimonenko's work, this article causes a lot of controversy. So, evidence is given of rather gross errors: a number of calculations turn out to be incorrect, as well as the proposal to use the material (insulator plus metal parts) is considered unacceptable for such work … That is, an article, as they say now "fake".
Nevertheless, the flying saucer, at least theoretically, Filimonenko was "built", and the goal set: to obtain a unidirectional driving force in a constant magnetic field (any, for example, the Earth), was achieved. The majority of those working with Ivan Stepanovich's materials agree on this. The point is only in production technologies - if they were needed at the time when Filimonenko was working, perhaps his "saucers" would already be flying.
But - there was no technology or testing. Another legend says that the intervention of Marshal Zhukov himself, and the death of Kurchatov and Korolyov, deprived Filimonenko of any support for further experiments and the practical implementation of his ideas.
