Theory of More Efficient Propulsion Method Explored

This document, a 1993 JPRS report, details a theoretical propulsion concept proposed by V. Shabetnik, a senior scientific associate at the NPO of Experimental Machine Building. The article, authored by Lieutenant Colonel V. Maksimovskiy, argues that traditional rocket propulsion is inefficient and proposes a new method based on high-temperature superconductivity. Shabetnik suggests that a spherical spacecraft, covered in a superconductive layer and equipped with three high-velocity electron accelerators, could achieve propulsion by interacting with the surrounding space, effectively creating a propellant-free engine. The document references a 1959 experiment by P. Oshchepkov regarding energy conversion as a foundational basis for these ideas. Furthermore, the report notes that experimental models using Y-Ba-Cu-0 type superconductors were tested in March and May of 1992, demonstrating a force of more than 22.5 grams. The author claims that these models exhibited instantaneous movements and changes in direction, drawing a comparison to 'flying saucers.' The report concludes by suggesting that while many obstacles remain, the development of a 5-meter prototype is a necessary next step for this technology.
