A new solar power satellite system faced to engineering: Concentric disc

Abstract

To release pressure of solar power satellite engineering, a concentric disc system model is put forward here. Classical Sandwich structure is abandoned for different requirement for planar accuracy between solar array and microwave power transmission array. The solar array is mounted with solar cell on both sides to reduce the system power dynamic range. The microwave power transmission disc circumrotates to maintain a perfect plane. Such a system can operate at increasing power level during its construction.
