Crts Reflectors
A design methodology for collapsible rib-tensioned surface (CRTS) reflectors is presented. Offset configurations are explicitly addressed. For a reflector with aperture of 10 m diameter and focal length of 7.8 m, a root-mean-square surface accuracy of about 2 mm is achievable; this result scales linearly with the diameter. The design of a 1.5 m diameter prototype is presented, and the accuracy ...
متن کاملReflectors for Solar Power
Manfred E. Clynes has since 1956 been chief research scientist at Rockland State, in charge of the Dynamic Simulation Lab. A graduate of the Univ. of Melbourne, Australia, and holder of an M.S. from Juilliard School, he has for the past 10 years been engaged in the design and development of physiological instrumentation and apparatus, ultrasonic transducers, and electronic data-processing systems.
متن کاملStiffened Springback Reflectors
The recently developed Spring Back Reflector has low stiffness in the deployed configuration. A general method of stiffening this type of reflector without changing its folding properties is presented. The stiffening is achieved by adding a conical skirt around the edge of the dish; this skirt snaps elastically when the dish is folded. The paper concludes that it is possible to design spring ba...
متن کاملDeployable Membrane Reflectors
This paper is concerned with the design of a new type of multi-purpose deployable membrane reflector. The reflector structure consists of a central expandable hub, a number of thin-walled foldable ribs connected radially to the hub, and a precision-shaped membrane supported and tensioned by the ribs. This concept is known as a collapsible rib-tensioned surface reflector. A methodology for the d...
