SUSTAINABLE AEROSPACE PROPULSION: THE SPINLOOP ROTARY ACCELERATOR WITH MAGNETIC LEVITATION FOR LOW EARTH ORBIT VEHICLE DEPLOYMENT
Abstract
The main goal of this work is to present the SpinLoop Rotational Accelerator project as a preliminary module for accelerating space rockets destined for low Earth orbit. By uti-lizing magnetic levitation technology, which is also used in modern high-speed rail sys-tems (including the thriving Hyperloop technology), it will be possible to design a device that imparts high velocity to the rocket immediately upon launch. This would reduce the amount of fuel the spacecraft would need, thereby decreasing its dimensions and con-struction costs. During the acceleration phase, the rocket would be positioned on a special platform that moves along a magnetic track. This platform would be responsible for bear-ing the load resulting from the rocket-s mass and the centrifugal forces generated during acceleration. The platform itself would be attached to an arm mounted on a shaft, which would receive torque from the propulsion system equipped with an appropriately selected gearbox and an electric motor. The entire setup would be placed within a vacuum cham-ber tilted relative to the horizontal plane, minimizing air resistance and significantly re-ducing power requirements. Once the desired rotational speed is achieved (and the result-ing linear velocity), the platform would detach from the arm and transition from the cir-cular track to a straight track. After stabilizing the trajectory, the rocket would separate from the platform upon exiting the tube, utilizing the imparted velocity to pass through the thickest atmospheric layers. Finally, in the later stages of the flight, rocket engines would be activated to place the vehicle into the desired orbit. This project holds great promise for reducing the costs of launching payloads into near-space and could revolu-tionize space transportation.
