Abstract Deployable solid-surface reflectors have been widely employed as the main part of antennas or telescopes in space observation and communication missions. The petal-type deployable solid-surface reflector has better package ratio and deploying properties. In order to balance the contradiction between simplification for mechanism reliability and development for structural stability, the petal-type deployable solid-surface reflector has been developed by a uniaxial rotation mechanism. This uniaxial rotation mechanism is deduced to fulfill the equivalent movement of New Petal-type Deployable Solid Surface Antenna (NPDSSA) by two orthogonal rotation mechanism based on Rodrigues Rotation Formula and Euler Angle Transformation Matrices. The general expressions of axis vector and rotation angle for uniaxial rotation mechanism are obtained to conduct parametric modeling. The 1.2-m aperture reflector as a case study is analyzed to explore kinetic properties of this model and the functions of the drag spring. It is indicated that this reflector by uniaxial rotation mechanism has a simpler mechanism and better kinetic properties than the original NPDSSA.

    Highlights New petal-type deployable solid-surface reflector by a uniaxial rotation mechanism. Deducing formulas to fulfill equivalent movement of original model. New model uses less driving energy with more stable deploying process. Drag springs provide integrity of solid surface and extra driving energy.
