E' così segreto che ci hanno già fatto persino un film, "caccia a ottobre rosso" , uscito nelle sale cinematografiche diciotto anni fa, nel 1990...
Ecco da dove prese l'ispirazione l'autore del libro:
"Nuclear Electric Magnetohydrodynamic Propulsion for Submarine
Authors: Adalbert A. Bednarczyk; MASSACHUSETTS INST OF TECH CAMBRIDGE Description: Master's thesis
Pages: 196
Report Date: MAY 89
Report Number: A104312
Abstract: This thesis analyzes the superconducting technology for a shipboard magnetohydrodynamic propulsion system. Based on the the principles of magnetohydrodynamics (MHD), the concept of open water efficiency was used to optimize the preliminary design of the MHD thruster. After the baseline submarine hull, modeled after the Los Angeles class submarine, was selected propulsive efficiency and the top speed for four variant MHD submarines were evaluated. The design criteria were set at a 100 MWt nuclear reactor power upper limit and a requirement of 30 knots for the top speed. This required advanced reactor plant and advanced energy conversion system. The selection of High Temperature Gas Reactor (HTGR) and Liquid-Metal Fast Breeder Reactor (LMFBR) was based on the combined merits of safety, environmental impact, high source temperature and maximum volume power density (KW/L). With the reactor outlet temperatures of 2000 K direct cycle energy conversion systems gave the best results in terms of thermal efficiency and propulsion plant power density. Two energy conversion systems selected were closed-cycle gas turbine geared to a superconducting generator, and closed-cycle liquid-metal MHD generator. Based on submarine reliability and safety the option of using an intermediate heat exchanger was also considered. Finally, non-nuclear support systems affected by the advanced power plant and MHD propulsion, stressing submarine safety, are proposed. (AW) "
Cioè, si tratta di un documento pubblico del 1989... ed ecco come è lo stato delle cose:
"A possible propulsion system for submarines is the magnetohydrodynamic drive, or "caterpillar drive", which has no moving parts. It was popularized in the movie version of The Hunt for Red October, written by Tom Clancy, which portrayed it as a virtually silent system. (In the book, a form of propulsor was used rather than an MHD.) Although some experimental surface ships have been built with this propulsion system, speeds have not been as high as those hoped. In addition, the great noise created by the formation of bubbles, and the higher power settings a submarine's reactor would need compared to a propulsor, mean that it is unlikely to be considered for any military purpose."
