Description

[Detailed Description of the Invention] The zero gravity of outer space is a completely different world for humans from life on earth. Gravity exerts a physical influence on human life activities on earth from the time of birth from the mother's womb.It is not limited to humans but all living things on earth, and it affects all living things on earth. Without the existence of gravity, life activities would be weakened, and for advanced organisms, a physical environment without gravity for a long period of time would become a dead world where life activities ceased. Creating a similar environment will make it easier for humans to operate in space, and will also ensure the continued activities of eternal life forms in space.

If it becomes possible for humans to live in space for long periods of time in the same way as on Earth, exploration into space will become a direct action, and the unknown world of space will become a space in which human activities can be carried out without any effort. The basic principle of an artificial gravity spacecraft is to rotate it, so the spacecraft's living room itself must be rotated. Rotation becomes smoother even with . The spacecraft also rotates with the living room (6) as the center of gravity (1).The centrifugal force acts in the direction of the floor (5). -If the human Kodama in the living room weighs 5Qkg, this rotation The rotational speed Vi of the body spacecraft must be set so that the centrifugal force on this human being is the same (50 kg is determined by the following formula), V = f, q is the acceleration of gravity, and r is the rotation.

．． 13. The speed per second of V is 3. of the radius of rotation.
At 13 times the speed, the same centrifugal force as gravity on Earth would be generated inside the spacecraft.

However, this centrifugal force is caused by the floor of the spacecraft, and the closer you are to the rotation axis than the floor, the smaller the centrifugal force becomes. A larger centrifugal force will act at a position greater than the distance between the rotating shaft and the floor.

If this rotating spacecraft is rotated at a speed per second that is 3.13 times the radius of rotation, the same gravity as on the ground will be generated, but the rotational energy required to rotate at this constant speed is given by the following formula.

J=τ・k2. J is the moment of inertia of the spacecraft, w is the weight of the spacecraft, and q is the acceleration of gravity.

k is the radius of the circumference from the axis of rotation to a certain point where the entire mass of the spacecraft is considered to be.

T==y:=, T is the torque, the peak is the angular acceleration, the number of revolutions per second is 3.13 times the radius, so it is approximately the number of revolutions per second, the peak = c
tz-Q, t is the time until the angular velocity reaches 3.13 times the radius per second, and W is the angular velocity.

W・1(2・π T=17 [kg-m].

, p is the power.

The rotational energy that produces the same gravity as on the ground requires only the power of this p, and if it rotates at a constant speed, the number of rotations per second of l is sustained. The consumed energy of a rotating constant-velocity rotating body is expressed as follows. .

p=pxdwn (kg-m/s').

μ is the coefficient of friction, d is the diameter of the rotating body, and W is its own weight.

Since n is the number of rotations per second, π is pi, and rotation in vacuum, μ is 0. Therefore, the consumed power p becomes 0.

Inside the spacecraft, the spacecraft rotates at a constant speed, so the only mass inside the spacecraft is centrifugal force that pushes it toward the floor. This is equivalent to gravity on earth for humans. Furthermore, even if the spacecraft is circular, if its center of gravity is not at the same position as the center of the circle, its rotation will be eccentric. Therefore, the center of gravity of the entire spacecraft must be at the same position as its axis of rotation.

This means that the mass of a person moving within the spacecraft changes the center of gravity of the spacecraft. There is a large difference between the mass of the entire spacecraft and the mass of a human being, but if the spacecraft rotates for a long period of time, the position of its center of gravity will change even slightly.1 To correct the center of gravity, the position of the axis of rotation is All you have to do is move something with mass inside the spacecraft so that the center of gravity is at .

Also, when designing a spacecraft, the mass of the entire spacecraft must be designed so that the center of gravity is at the center of the spacecraft.This is an absolute condition.If the axis of rotation is eccentric, the human In addition to this, a propulsion rocket for multiple rotations can also help with the correction of the 1M core, which causes the weight to become heavier or lighter at one-second intervals. Another problem with the rotation of a spacecraft is lateral vibration. Even if the center of gravity and the axis of rotation are in the same position, if the axis of rotation is at an angle, a person would stand diagonally on the floor of the spacecraft. If lateral shake rotation occurs, either stop the rotation, stop it, and then rotate it again, or install multiple thrust Rokeno L-E spacecraft on the side of the spacecraft to correct lateral shake. There is a need.

Earth's gravity on humans has continued to affect living organisms during their evolution from primitive single-celled organisms to advanced organisms since the beginning of recorded history. Even other lower living organisms would be unable to maintain long-term life if this gravity were to disappear.Gravity is the basis of the physical environment for earth-shaped organisms, and it is the basis of the cellular environment. Gravity also served as the basis for the evolution of physiological and biochemical matters. In addition to this, for animals on land, there is air at a pressure of 1 atmosphere, water, food, light, and gravity to sustain the life of terrestrial creatures.

[Brief explanation of drawings]

The diagram shows the configuration of the spacecraft. (1) is the center of gravity or the rotation axis, (2) is the contact point of the outer circumference of a straight line passing through the rotation axis, (3) is the contact point of the outer circumference of a straight line that spans the rotation axis, (4) is the ceiling of the spacecraft accommodation room, (5) is the floor of the spacecraft living room, (6) is the spacecraft living room, (7) is the distance from the center of gravity of the spacecraft to the floor of the living room, and (8) is the direction of rotation.

Claims (2)

[Claims] (1) Change the shape of the spacecraft to the rotating spacecraft shown in the figure [(1)] and rotate the spacecraft with the center point of the rotational shape as the rotation axis.The inside of the rotated spacecraft is A centrifugal force proportional to the distance from the rotation axis and the number of revolutions per second is generated inside the spacecraft. This centrifugal force changes into gravity for objects with mass inside the spacecraft, creating a zero-gravity state inside the spacecraft. A rotating spacecraft that creates a gravitational force inside the spacecraft that is equal to the gravitational force on Earth, creating a physical environment where humans can live in space that is equivalent to that on Earth. (2) A circular rotating spacecraft must be rotated in space. The power for rotation is (inner) the center axis of the circular spacecraft, and the straight line passing through (1) in the figure is the circular spacecraft. Two propulsion rockets are installed at the two points (2) and (3) that intersect with the outer periphery.
In this case, the propulsion directions are opposite to each other with the central axis (1) as the base point, so the central axis (1)
is the axis and the spacecraft rotates. Also, the center of gravity of the entire weight of a circular spacecraft must be the central axis (1) of the circular type. Under this condition, the spacecraft is equidistant from the central axis (1). Certain equal propulsion rockets will rotate around the central axis (1) with equal thrust at the same time, and the rotational power is the minimum number for two thrust rockets to rotate with the rotation axis as the base point. A power rocket for spacecraft rotation that can also use multiple thrust rockets based on the rotation axis as rotation power.
