Abstract
The project focuses on the development of a proof-of-concept model of a planer and parabolic membrane reflector antenna. The research work mainly includes the mechanical design of the inflatable antenna design technology. It is required to investigate different types of folding techniques and design a suitable folding method for planer and parabolic antenna assembly.
The other major research problem is to analyze different rigidization techniques for inflatable membrane structures. The antenna assembly needs to be rigidized after the removal of internal gas pressure to maintain its structural properties.

Abstract
This project deals with the development of inflatable technology applicable to large, lightweight structures and apertures. Areas of specific interest are Inflatable structure with minimum surface error for shape control of large membrane mirrors and antennas, fold line behavior in membrane reflector, methods to minimize RMS surface error, wrinkle-free design of tensioned membrane, controlling structural geometry and dynamics. This research will provide valuable knowledge regarding the complex dynamics of such structures to improve their precision considerably.
Results and the skills gained by the personnel involved will be in demand by the space industry and organizations related to aerospace systems. Also, the long-term effects of this research will be beneficial to any engineering application consisting of hybrid structures (solid/cable elements). Research data for Kapton and Mylar membranes will also impact other engineering fields such as MEMS technology and electronic devices.

Abstract
The objective of this research is to understand the behavior of an Adaptive membrane model using geometric and material performance, considering orbital and launch conditions. The effects of the physical characteristics like the pre-stress, launch and orbital loads, etc. help to understand the non-linear analysis in terms of other details of dynamic characteristics of mode shape and the natural frequency.
Wrinkle & creases effect on surface-RMS, distribution of shape error across the surface, the effect of piezo-patches on the dynamics & shape of the membrane model, and the orientation(s) of the patches, etc. helps in robust design of space antenna in orbital and launch conditions.
