Inertial propulsion

Jump to: navigation, search

The Inertial propulsion is concept of violation of the physical law of conservation of energy-momentum due to some special redistribution of momentum of some isolated system among its component.

The inertial propulsion is suggested for movement of vehicles, aircrafts and spacecrafts. The device that realizes the inertial propulsion is called inertioid or gravitsapa.

The first described in the literture attempt (and, according to the story by Rudolf Erich Raspe, successful) to use the inertial propulsion is attributed to baron Munchausen, who got up himself (together with his horse) out from the swamp, just pulling himself for his hair [1].

Then, the most famous claims for the realizations of the propulsion system that does not require the loss of mass are the Dean Drive by Norman L. Dean [2][3] and the Gravitsapa by Valery Menshikov [4].

Due to the principle of relativity, the inertial propulsion is an equivalent of the perpetual motion of first kind [5].

At the local conservation of the momentum, the inertial propulsion implies that the sum of momenta of an isolated system depends on the order of summation, at large enough values of the number of summands; this means the existence of the Mizugadro Number.

Our institute's staffers have been developing a non-jet propulsion unit for several years in a row, Valery Menshikov, who heads this institute, said in mid-March. A liquid or solid-state propulsive mass moves along a preset tornado-shaped trajectory inside this engine, thereby ensuring sustainable propulsion. Quite possibly, we are witnessing a hitherto unknown interaction between the propulsive mass and little-studied fields, including the gravitation field, Menshikov explained.
