“…But how to determine the pre-shape configuration and the prestress was not theoretically given there. In [27], the initial geometric configuration was obtained using the differential geometry and elastic mechanics given the inflation press and the target shape of the inflated membrane reflector. However, the assumption of the membrane boundary condition therein was inconsistent with the real one, so the high quality membrane shape was not acquired.…”

“…However, there is a limit t the constraint in the payload of the launch vehicle. This constraint can be overcome using a new type of space antenna using inflatable technology [5] Since successfully launch and deploy a 14meter diameter inflatable o in 1996, NASA has continued its study on concepts and technologies for long mission supported by large rigidizable structure [3] and dynamic behaviour of inflatable parabolic str [31]. The inflatable solar array is another structure that benefits from inflatable technology.…”

This is an overview topic of inflatable structure for aerospace application. An inflatable structure is a promising choice for a wide r application are inflatable wing, space antenna, solar array, inflatable aeroshell and inflatable aerodynamic decelerators. The advantages of inflatable structure are it offers the potential for compact stowing of lightweight structure. This will efficient packaging, easy to deploy and ultimately lead to reduction in mission cost.Historically, inflatable technology has been introduced as a concept in aerospace application with a patent on flying glider th Over the years, many concepts of inflatable were introduced but only a small number of concepts have progress beyond the stage of design and even fewer manage to be completed and used extensively.

“…Space membrane structures have many advantages, including lower manufacturing cost, lighter weight, and smaller launch volume. They have been applied in inflatable antennas [1], sunshields, inflatable aerodynamic decelerators, inflatable inhabited structures, and sail arrays. Flexible laminated membranes, particularly Al-Kapton membranes and Al-Mylar membranes, have received much attention in the fabrication of flexible thermal protection systems in sunshield structures, supersonic inflatable aerodynamic decelerators [2], inflatable modules, and lunar habitats [3].…”

Al-polymer laminated membranes are widely used in large aerospace structures. When the laminated membranes are pressurized, wrinkles emerge, which have an important effect on the performance of the structures during operation. This paper describes the numerical simulation and experimental investigation of wrinkles in laminated membranes. The nonlinear postbuckling analysis method, based on laminated thin-shell elements, was used to simulate the onset, growth, and final configuration of wrinkles when laminated membranes are subjected to external loads. The simulations are conducted with the ANSYS finite element package. Changing regularities of number, wavelength, and range for the wrinkles during the onset and growth processes are investigated. The wrinkles of laminated membranes with different design parameters such as material selection, ply number, ply angle, and ply mode are predicted. Devices that can be used to clamp and load laminated membranes in several load cases were designed and developed. A 3D photogrammetry system was constructed to characterize wrinkling patterns of laminated membranes subjected to shear displacement loads. By comparing the results of numerical analysis and experimental results, the accuracy of the numerical analysis method was verified. This study work is expected to inform wrinkling simulation and shape control of aerospace laminated membrane structures.
