Design Summary

Shape/Configuration

by DiscoveryOne / Design Pane / 1

The basic concept is that of a grow-as-you-go design for a space habitat, which could ultimately be used as a space-based transport. The design consists of a hub powered by maglev rotors, rotating an outer hub with guiding rails supporting wedges attached by cables, in a bycicle wheel manner (patent pending).

Central Hub

by DiscoveryOne / Design Pane / 2

The hub is 10M+ in diameter, and 20M+ in height, with two maglev, linear induction rotors on either end. The frame of the hub is built like that of a submarine in order to handle buckling forces. The alternative design is to house the stators in the inner hub.

Maglev/Induction

by DiscoveryOne / Design Pane / 9

Magnetic inductione with stators and rotors, is the preferred approach to power the rotation of the outer hub. The basic design is that of a set of LIMs or Linear Induction Motors. Linear is, in our design, not indicative of the direction of motion.

Guide Rails

by DiscoveryOne / Design Pane / 3

The guide rails are placed on both ends of the outer hub, and are 1.5M+ in width. They are built like trusses, and are strengthened with cables. The outer end of the guiding rails is used for jettisoning unwanted cargo, through an elevator like shaft built within the guide rails. An elevator system may also be added to the guide rails.

Wedges

by DiscoveryOne / Design Pane / 3

Each wedge is 17M+ in length, 5M+ in height and width. The wall of each wedge is made-up of 3D-molded carbon/plastic plating, and is covered with a thin layer of aluminium and silica foam. The frame is made of titanium. Docking doors are placed in the center of the wedge and are 2M+ in width. The sub floor of each wedge is 1M+ in height, and ceiling about 0.5M+ in height.

Control Moment Gyros

by DiscoveryOne / Design Pane / 1

The DiscoveryOne©® requires the aid of CMGs located in the hub for attitude control and stability. Three gyros are to be designed into the structure of the static inner hub. They will be synced to stabilize the hub. Since the inner hub does not rotate, spacecrafts, coming in for docking, do not have to rotate on their own axis.

Docking

by DiscoveryOne / Design Pane / 5

A docking structure is added to either end of the hub. The docking area should not exceed 3M+ in diameter -- dimensions are derived from the geometry of the bicycle wheel cable design. Most docking assemblies are extensible and are able to form walkways and guardrails. Their covering is made up of layers of UHMWPE (kevlar, dyneema, or linar), titanium woven wire meshes, and thermal linen.

Control Center

by DiscoveryOne / Design Pane / 4

The control center is located in the hub, attached to the center bulkhead, of what would be considered in space, the floor of the hub. Console areas are made of touch panels, and are liguid-proof along with the OLED screens. Status of all on-board systems, including the status of all systems on every wedge is relayed to the center hub, and displayed on status screens. Audio and video streams are relayed to each wedge from the center hub.

Foam & Coatings

by DiscoveryOne / Design Pane / 7

The entire frame is coated with a layer of silica areogel. Battery casings and carbon-fiber electrical conduits are filled with foam areogel to prevent electrical fires. Aerogel panels are used between each wedge's interior and the frame for sound and thermal proofing.

Panels

by DiscoveryOne / Design Pane / 16

Each wedge is covered with 3D-molded panels made of silica [LI-2200] and boron carbide with poly-amide as the sandwidching material. The same type of panels protect onboard electronics.

Interior/Furniture

by DiscoveryOne / Design Pane / 10

All the interior surfaces are covered with carbon-fiber paneling. The furniture is made of aerogel blocks wrapped by thin carbon fiber panels (patent pending). Support structures made of carbon fiber trusses are used for furniture anchors and are collapsible and tuckable.

Seatings

by DiscoveryOne / Design Pane / 11

Seats come in several varieties, simple fixed ones, with a hard bench-like surface for the dining area. Cushioned seats are used in the multimedia wedge. Cushioned seats and beds are used in the private quarter wedge. Bamboo linen is used for seat and bed coverings, and down duvet is used for filling and cushioning material.

Power Generation

by DiscoveryOne / Design Pane / 13

Fuel cells are used to provide electrical power for onboard devices and machinery. Solar concentrators are used for additional power and to recharge batteries. Some power will also be extracted from the spinning gyros onboard the hub. The use of our π generator may also be included.

Bioreactors

by DiscoveryOne / Design Pane / 8

Bio-reactors are used for most of the onboard life pathways. For the hydroponics wedge, the sodium hydroxide pathway may be used for oxygen production and heat, if it can be turned into a closed loop system.

CO2 Scrubbing

by DiscoveryOne / Design Pane / 15

The space shuttle closed loop lithium hydroxide scrubber is used. The sodium hydroxide path may be used, if a closed loop path can be engineered.

Oxygen Production

by DiscoveryOne / Design Pane / 14

Algae bioreactors are used to produce oxygen. The excess of oxygen is used to soak canisters of an oxygen soaking substance. These canisters are kept for backup oxygen, and for the space pods. The backup canisters are slowly re-heated to extract the oxygen required for a given number of persons.

Food and Water

by DiscoveryOne / Design Pane / 15

Astronauts ration is used for food. Additonal food may be provided by bio-reactors and the hydroponics wedge. Some of the food rations are micro-wavable

Body Cleaning

by DiscoveryOne / Design Pane / 13

Alcohol-laced tissues are used for body cleaning.

Garbage Disposal

by DiscoveryOne / Design Pane / 13

Bio-reactors are used for garbage disposal of anything made of cellulose fiber. Human excreta are fed to bio-reactors to generate alcohol, and other useful by-products.

Recycling

by DiscoveryOne / Design Pane / 1

Recycling of any on-board may be impossible; therefore, the use a plasma-burner fed by peroxyde, located between bulkheads on the center hub is the approach selected for disposal on substances and material that cannot be processed by chemical or biological reactors.
