Description:

The varying force of wind along the length

of the atmospheric portions of KESTS

is compensated for by a servomechanism proposed

in this file. The exit of the mass stream

earth surface re-accellerator is reconfigured to provide

a symmetrically divergent set of mass streams, which are then

gradually reconverged by a sequence of deflection yokes

as the mass stream rises up through the atmosphere; unbalancing

the symmetry of a deflection yoke unbalances the force against the mass

stream,opposing wind force.

ABSTRACT: KESTS wind force compensation concept:

At earthsurface re-accelleration site, launch kinetic energy

mass in 3 or more streams symmetricaly divergent, re-formed

at several altitudes in atmosphere. An outer sheath, in

sections between re-focuser magnetic tensile rings, senses

wind-caused miniscule displacement of sheath relative to

stream-tube. The local focuser then servos in an unbalanced

mode, applying force to compensate for the expected effect

of wind force.

BRIEF DESCRIPTION:

The force of the wind on a Kinetic Energy Supported

Transportation Structure which reaches from the surface of

the Earth out to space is one of the main concerns regarding

the feasability of such a transportation system. The

concept being presented here proposes a specific mechanism

for compensating a KESTS structure for the force of wind

pushing against it.

This is a servomechanism, using relative displacement

feedback signals from a lightweight windblown sheath around

the KESTS, and applying appropriate unbalanced force from a

set of normally balanced mass streams which comprise the

KESTS supportive energy stream.

The source of energy for the servomechanism is created

by causing the configuration of the KESTS mass stream to be

that of three or more symmetrically divergent mass streams,

at the exit of the earthsurface stream re-accellerator.

These mass streams are re-converged at various altitudes

within the atmosphere, at sites of electromagnetic clusters

of mass stream deflectors. These electromagnetic rings may

be thought of as a focusing mechanism acting upon the group

of KESTS mass streams.

When no windforce is acting upon the KESTS, the set of

stream focusing rings gradually reconverge the set of mass

streams into a single mass stream by the time the stream

reaches an altitude above which windforce may be considered

insignificant.

When wind force is present, the focusing rings symmetry

is deliberately unbalanced appropriately to exert a force

between the focusing ring and the centerline of the mass

stream; this unbalance within the set of mass streams is

absorbed in a feedback manner as the streams continue up

through subsequent focusing rings.

The focusing ring which initiated the unbalancing force

now has an equal but opposite force exerted upone it by the

unbalanced deflections of the reconverging mass stream. This

force is mechanically transferred to an outer sheath of the

KESTS which spans from one focusning ring to the next one.

This force on the outer sheath is thus in opposition to the

wind force externally imposed upon it.

When the computer controlled servo system determines

that the aggregate set of wind forces against it would move

it off of centerline at the upper focuser ring, then the

mass stream re-accellerator proportions mass into the

appropriate mass stream to exactly oppose the algebraic sum

of wind force against the KESTS tube, thus maintaining

position at the focusing element just above the

atmosphere.The atmospheric section length transit time of

any given mass element in the KESTS mass stream, moving at 5

to 10 miles a second, is short in relation to wind force

change rate.

Wind sensors along the outer sheath provide the signal

source for the servo system.

VALUE:

This wind compensation servo mechanism would enable a

stable position of the KESTS just above the earth's

atmosphere, regardless of the wind conditions of the

atmosphere below it. This would eliminate the need for

sufficient elastic strength of a KESTS outer tube extending

the full length of the KESTS, saving the energy expenditure

required to support that extra strength sheathing material

weight. Thus the value is that of lowered cost of

construction material, and of lowered rate of electrical

energy consumption of the supportive system, as well as the

increased overall feasability of the KESTS TO GEO HABITAT

RING concept.

PERFORMANCE CHARACTERISTICS:

The amount of stream deflection at any given focuser

electromagnet needs to be greater than the maximum force

expectable due to wind force on that section of stream

sheath. The sum of the maximum windforce at any given

direction integrated from the earth surface to the top of

the atmosphere, needs to be less than the deflection force

necessary to completely reconverge the appropriate mass

substream's divergence angle as it exits the earthsurface

re-accellerator.

ENABLING TECHNOLOGIES:

The basic KESTS technology is that of the

electromagnetically coupled exchange of energy between the

kinetic energy of a stream of very fast moving objects, and

the evacuated tubing which sheathes the mass stream. The

re-accellerator technology which senses the position and

rate of change of position of each stream object passing by,

and applying appropriate electromagnetic force timed to

re-nominalize the velocity of the object, needs only to be

recofigured to provide the divergent mass streams at the

exit of the re-accellerator. Wind advance sensing would be

from lightweight vanes along the outside of the KESTS

sheath. The computer operated servo system coordinating the

many individual electromagnetic focusing elements on the set

of focusing rings which reconverge the mass stream as it

rises up through the atmosphere would need to have an

appropriate program written for the servo complex. The

energy used to power the focusing electromagnetic coils is

derived from the average flow of kinetic energy of the mass

stream itself, as it supports the weight of the ring in the

earth's gravitational field, the same as that used to

support the KESTS tube elsewhere: The alternating magnetic

field created along the KESTS due to the discrete magnetic

elements represented by the magnetic field of each high

velocity object in the mass stream, induces current flow in

a nearby electromagnetic coil: the impedance of control

elements within the coil's circuit is servoed to vary the

electromagnetic force on the coil at any given moment. This

translates into a temporary change in force against the pull

of gravity on the mass of the coil, which is quickly

conmpensated by response from the appropriate divergence of

mass streams at the re-accellerator's exit.

RELATION TO MAJOR MISSION OBJECTIVES:

Given the major mission objective of creating a

transportation system capable of transporting the major

portion of earth's population to a ring of space habitats

filling geosynchronous earth orbit, enabling the continued

increase of civilization while allowing the restoration of

earth surface ecosystem balance, the wind force compensation

concept presented above provides a refined mechanism for

compensating for varying wind force against the KESTS, thus

increasing the feasability of the use of KESTS to achieve

the major mission objective.
