G11.2.2. Landing sites in which magnetic circuits looped along the surface of the ground


Figure G35 presents a Magnocraft which hovers in the inverted position. The height of it is such, that main magnetic circuits (M) are looping back just as they touch the surface of the ground. Just such touching of surface of the ground with main magnetic circuits (M) allows for an automatic detection of changes in magnetic energy flow through these circuits in moments when the vehicle either slightly lowers the height thus submerging its circuits underground or slightly lifts up thus shifting these circuits above the ground level. Therefore, it is this unique kind of the landing that is going to be frequently used by the Magnocraft crew for automatic “parking” of this vehicle – see descriptions of “anchoring” of Magnocraft provided in the final part of subsection G11.
In the case of parking of Magnocraft discussed here, the pattern of marks formed in the throbbing mode of operation takes the form illustrated in part b) of Figure G35 and composed of one central spot "C" and a number of concentric trails "M". The spot "C" is formed by the pillar of the central magnetic circuit. In turn each separate trail "M" is scorched by one of the main circuits (as this is explained in subsection G7.1 - such main circuits (M) join the main propulsor of the vehicle with every operative side propulsor).
In the magnetic whirl mode of operation, the Magnocraft which hovers in a hanging position causes a slightly different pattern - see part c) of Figure G35. In this case, one circular, wide strip of damaged soil replaces the previous concentric trails. In this strip not only damage originating from a magnetic field is to occur (described in detail in subsection G11.1), but also mechanical destruction is to appear caused by a spinning of ionized air that follows the magnetic whirl.
It should be noted, that the width of a scorched trail for the landing in an inverted position described in this subsection (i.e. when the main magnetic circuit (M) just touch the soil with their returning loops) is much narrower than the one produced by a Magnocraft landed in an upright position. After appropriate simplifying assumptions are taken, it can be shown, that for these cases of landing Magnocraft the following corrective equations are in force:

a) For landings in a standing position: d = 2di – (do – di) (G38)
 

b) For landings in a hanging position: d = 2do + (do – di) (G39)

in which “do” and “di” represent outer and inner diameter of the scorched ring “M” of grass visible in part “c” of Figure G35. Equation (G38) realises, that during landings in a standing position, the inner diameter “di” of the ring of vegetation scorched on these landing sites, minus the thickness of this ring “(1/2)(do-di)”, is usually equal of a half of nominal diameter “(1/2)d” of the Magnocraft which landed in a given positioning of its magnetic circuits. In turn equation (G39) realises, that during landings of the Magnocraft in a hanging position, the outer diameter “do” of the ring of vegetation scorched on these landing sites, plus the thickness of this ring “(1/2)(do-di)”, are usually equal together to a half of nominal diameter “(1/2)d” of the Magnocraft that landed with such orientation of its magnetic circuits. The above can be expressed in another form, namely that the diameter of the landing site scorched during
anchoring the Magnocraft will be close to a half of the nominal diameter “d” of the landed vehicle, while depending on whether it is smaller or greater than that “(1/2)d” it can be determined whether a given vehicle parked in a hanging or standing position.
Figure G35 presents the situation where the inclination angle (I) of the Earth's magnetic field is equal to 90 degrees. (I.e. the situation when this environmental magnetic field is perpendicular to the surface of the soil – as it happens only on magnetic poles of Earth and on selected slopes of some hills.) Therefore all marks illustrated there are located symmetrically in relationship to the central point of the landing. But in reality the value of this angle changes with the geographic latitude at which the Magnocraft lands, and sometimes also with an angle of a slope of hill. Therefore the pattern of marks presented in Figure G35 in real cases must also be appropriately altered (deformed).
