Mechanics Design of Conical Spiral Structure for Flexible Coilable Antenna Array

Limited by the effective launch capacity of a rocket, deployable antenna is very important in design spaceborne array. Compared to traditional antenna, flexible coilable array has higher surface precision and better vibration control therefore more suitable for high frequency communication. In order minimize weight satellite reduce cost its launch, guideline geometry parameters crucial. Existing models cannot be directly applied interaction large deformation between membrane conical spiral Hence, structure thickness have not been optimized yet. this paper, concial analyzed A concise formula derived predict critical force that flattens coiling scroll. Combined with theoretical model membrane, provides an support lightweight mechanical array, such as membrane. The proposed validated experiments. above findings potential applications reduction costs.
