A Transit Gate Ring: Power Scaling and Thermal Load for a Fifth-Coordinate Portal of Stated Aperture

This paper presents a complete design study of the device is a circular gate ring, scanned from half a metre to five metres in aperture radius, that sustains the boundary conditions for a fifth-coordinate transit at a stated operating parameter, derived from stated assumptions and computed throughout by the accompanying script. Gate power follows aperture area: the two-metre reference ring requires 6.17 MW, and rejecting thirty-five percent of that as heat at 600 K requires 345.7 m^2 of radiator at a radiative flux of 6.25 kW/m^2. Larger gates gain no efficiency, only aperture. Every figure in the study is a computed result of the stated model and nothing was built or tested: the study is SIMULATED, NOT MEASURED, and its limits are stated as plainly as its performance.
