“…Since the initial IRDT flight was largely unsuccessful a reflight was planned (IRDT-2). Reference [ 80 ] describes the improvements to the heatshield design, pressure control system, data acquisition and telemetry system. Improvements were based on the desire for more complete information in the case of a failure.…”

Ballute aerodynamic decelerators have been studied since early in the space age (1960's), being proposed for aerocapture in the early 1980's. Significant technology advances in fabric and polymer materials as well as analysis capabilities lend credibility to the potential of ballute aerocapture. The concept of the thin-film ballute for aerocapture shows the potential for large mass savings over propulsive orbit insertion or rigid aeroshell aerocapture. The mass savings of this concept enables a number of high value science missions. Current studies of ballute aerocapture at Titan and Earth may lead to flight test of one or more ballute concepts within the next five years. This paper provides a survey of the literature with application to ballute aerocapture. Special attention is paid to advances in trajectory analysis, hypersonic aerothermodynamics, structural analysis, coupled analysis, and flight tests. Advances anticipated over the next 5 years are summarized.

“…Current developments mostly focus on two types of structures: the inflatable and the mechanically deployable structures. The inflatable structures are based on flexible thermal protection materials supported by air-tight chambers that deploy and sti↵en when inflated by an on-board gas source or ram air [11,12,13,14,15,16]. The mechanically deployable structures are usually umbrella-like mechanisms consisted of rigid components as the skeleton and flexible thermal protection materials as the skirt [4,17,18,19].…”

“…With the development of material technology, even some new types of inflatable fabric (e.g. inflatable antenna, flexible solar sail) with special use and shape trend to replace the original rigid structure or design [1][2][3][4]. However, the inflating and deploying of inflatable fabric are the most important and dangerous processes.…”

In order to model complicated folded fabric, this paper proposed a new reverse modeling method. Two kinds of concrete implementation were investigated, which were based on graphical deformation and nonlinear dynamics, respectively. The first method learned from Free-Form Deformation technology is used to form the regular folds, while the element distortion rises. The second method adopts a fluid structure interaction algorithm to form the irregular folds. Both methods can transform the finite element model from expanded state to initial folded state without changing the mesh topology. Therefore, the mapping relationship between the finite element models of expanded state and folded state can be naturally obtained. Then, the initial stress used to modify the model can be calculated according to the mapping relationship, and the modifying can ensure the accordance of inflated flexible fabric’s geometry and the original design. At last, the finite element model of an inflatable fabric, which cannot be modeled by exiting method, was established by the new reverse modeling method with its feasibility and accuracy verified by comparing the calculation results. The results of this study could provide a reference for modeling complicated folded fabric.
