StarCycler

StarCycler represents a novel approach in the design of Artificial Gravity Space Habitat, characterized by its distinctive smaller, wider profile. In contrast to traditional designs, StarCycler's compact shape enables easier assembly, while its increased width amplifies the volume of the biohabitat. Notably, the station addresses concerns regarding gyroscopic stability through the implementation of a simple spin balance system.[1].

Overview:

edit

Artificial gravity has long been recognized as a potential solution to many of the physiological challenges faced by astronauts during extended space travel[2]. Centripetal acceleration generated by a rotating space station offers an ideal approach[3]. However, determining the optimal size, rotational rate and necessary Artificial Gravity of such a station remains an ongoing challenge[4].

Added to this challenge are considerations of cost, launches, and assembly. The StarCycler addresses all these relevant factors through its simple design, notably emphasizing the spaciousness of the bio environment.

Coriolis Effect:

edit

The Coriolis effect describes the sensation of motion experienced by the inner ear when the head is rotating[5]. Earth-based studies, notably those employing rotating rooms[6], have yielded anecdotal insights into the effects experienced at different rotation rates, establishing a comfort zone for Coriolis effects at rates below 6 rpm[7].

Other Ailments:

edit

In space, vascular changes and bone loss in passengers stem from the absence of gravity[8]. The acquisition of empirical studies on this subject can solely be conducted aboard a rotating space station. Of particular concern is understanding the minimum Artificial Gravity required to sustain healthy physiology[9]. Even more critical is the reacclimation process to Earth’s gravity upon return[10]. StarCycler's variable speed capability will be pivotal in determining the optimal gravity and rotational rate to mitigate these physiological effects

Station Size:

edit

For construction purposes, it is crucial to select a station with the smallest radius capable of producing a significant amount of Artificial Gravity within the Coriolis comfort zone. This can be achieved with a station having a rotation rate of 5.2 rpm and a diameter of 150 feet.

This configuration ensures that it comfortably falls within the Coriolis comfort zone and will generate approximately 0.7 times Earth’s gravity, facilitating a smooth transition for occupants upon their return to Earth.

Construction:

edit

The StarCycler utilizes the booster fuselage as the initial platform for construction and habitation. A Tensegrity spoke system[11] is then used to envelop the core, followed by the completion of Phase One with a sectional inflatable.

Gyroscopic Stability:

edit

While a torus-shaped station may provide excellent gyro stability, it could potentially limit the station's maneuverability in response to internal or external perturbations[12]. In a real sense gyro stability is inversely proportional to controllability.

StarCycler semi-unstable shape addresses this concern by implementing a spin balance system capable of adjusting the station’s momentum profile. This capability allows for a transition from a semi-stable state to a more gyro-efficient profile, enhancing the station's control and responsiveness.

Station Control:

edit

StarCycler forms a force-distributive geodesic structure Weighted bogies travel along this structure, facilitating momentum transfer to to maintain a radial or preferred momentum profile.

Power:

edit
 
GEM- Gyro-Electro-Momentum motor

A massive Control Motion Gyro known as GEM is a motorized Gyro flywheel located at the centroid powers the station[13] and contributes to stabilization and orientation maneuvers[14].

Being located Center of Rotating Mass gives GEM very unique abilities.

Habitat:

edit

StarCycler boasts an impressive 2 million square feet of biohabitat, offering multiple gravity zones and a free-floating atrium, enhancing the overall living experience for its occupants[15]

Sustainability:

edit

The lightweight design of StarCycler minimizes the demand for Earth's natural resources, enabling mass production and potentially alleviating stress on Earth's ecosystem. Sustainability is paramount in paving the way for the colonization of space.

Conclusion:

edit
  1. Phase one is an inexpensive test platform.
  2. Simplistic in-space construction.
  3. Large enough to obtain invaluable science
  4. Minimal rocket launches
