    How to make an inflatable sphere aka “carbon bubble”? The inflatable carbon bubble is a great tool to transform a protest into a highly playful, fun and interactive event and at the same time raise awareness about the carbon bubble issue.*1 The making of the inflatable can be an inspiring group activity. It can be also used for symbolic or direct action: for example the popping of the inflatable carbon bubble can be very powerful to tell and visualise the future market crash of the fossil fuel industry.

    05WAC-61 Design and Flight Testing of Inflatable Wings with Wing Warping Jamey D. Jacob, Andrew Simpson, and Suzanne Smith University of Kentucky, Lexington, KY 40506 Copyright c 2005 Society of Automotive Engineers, Inc. ABSTRACT The paper presents work on testing of inflatable wings for unmanned aerial vehicles (UAVs). Inflatable wing his- tory and recent research is discussed. Design and con- struction of inflatable wings is then covered, along with ground and flight testing. Discussions include predictions and correlations of the forces required to warp (twist) the wings to a particular shape and the aerodynamic forces generated by that shape change. The focus is on charac- terizing the deformation of the wings and development of a model to accurately predict deformation.

  • Advancement in Inflatable – “A Review”
    International Journal of Engineering Research and Technology. ISSN 0974-3154 Volume 6, Number 4 (2013), pp. 477-482 © International Research Publication House http://www.irphouse.com Advancement in Inflatable – “A Review” Richa Verma 1M.Tech Student, PEC University of Technology Chandigarh. Abstract With the increase in a continued human inquisitiveness, work has been done in the development of inflatable structures. The concept of inflatable structures includes light-weightiness and deployable parts. These parts utilize the theory of membranes, hybrids and composites. These inflatable structures offers great advantage for the building of Convertex emergency air shelter, Balloon used in defense sector, Military tents, Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags and so on. Apart from this they also prove their importance in space stations for building of the terrain on moon and mars too. These light weight structures are of particular interest due to the requirement of small storage space in deployed condition, their maximum load capacity and their adaptable frame-work. The paper presents a review of the advancement and innovations, both in its prior and current phase, in inflatable technologies. Keywords: Inflatables, light-weightiness, deployable, maximum load capacity, adaptable frame-work. 1. Introduction Scurlock (1959) conceptualized the first inflatable in Shreveport, Louisiana. He is a pioneer of inflatable tents, inflatable domes. His tremendous accomplishment was the introduction of the safety air cushion. These cushions are used by fire and rescue department. Scurlock (1986) established the first Fun factory in Metairie, Louisiana. This factory was overall made of inflatable. In 1967 a pressurized top known as “Space walk” was incorporated.

  • Inflatable Technology: Using Flexible Materials to Make Large Structures Douglas A
    Inflatable technology: using flexible materials to make large structures Douglas A. Litteken* NASA Johnson Space Center, 2101 NASA Parkway, Houston, TX, USA 77058 ABSTRACT Space structures are one of the most critical components for any spacecraft, as they must provide the maximum amount of livable volume with the minimum amount of mass. Deployable structures can be used to gain additional space that would not normally fit under a launch vehicle shroud. This expansion capability allows it to be packed in a small launch volume for launch, and deploy into its fully open volume once in space. Inflatable, deployable structures in particular, have been investigated by NASA since the early 1950’s and used in a number of spaceflight applications. Inflatable satellites, booms, and antennas can be used in low-Earth orbit applications. Inflatable heatshields, decelerators, and airbags can be used for entry, descent and landing applications. Inflatable habitats, airlocks, and space stations can be used for in-space living spaces and surface exploration missions. Inflatable blimps and rovers can be used for advanced missions to other worlds. These applications are just a few of the possible uses for inflatable structures that will continued to be studied as we look to expand our presence throughout the solar system. Keywords: Deployable structures, inflatable structures 1. INTRODUCTION The dream of human exploration beyond our home planet has excited and inspired generations across the world. The dreams of taking vacations to the Moon, visiting cities on Mars, or traveling through black holes to discover new life in other galaxies have been described in fiction stories for decades.

  • De-Orbiting Small Satellites Using Inflatables Aman Chandra Space
    De-orbiting Small Satellites Using Inflatables Aman Chandra Space and Terrestrial Robotic Exploration Laboratory, Department of Aerospace and Mechanical Engineering, University of Arizona Jekanthan Thangavelautham Space and Terrestrial Robotic Exploration Laboratory, Department of Aerospace and Mechanical Engineering, University of Arizona ABSTRACT Small-satellites and CubeSats offer a low-cost pathway to access Low Earth Orbit at altitudes of 450 km and lower thanks to miniaturization and advancement in reliability of commercial electronics. However, at these low altitudes, atmospheric drag has a critical effect on the satellite resulting in natural deorbits within months. As these small systems further increase in reliability and radiation tolerance they will be able readily access higher orbits at altitudes of 700 km and higher, where atmospheric drag has little to no effect. This requires alternative technologies to either de-orbit these small spacecrafts at the end of life or move them to a safe parking orbit. Use of propulsion and de-orbit mechanisms have been proposed, however they require active control systems to be trigged. Other typical de-orbit mechanism relies on complex mechanisms with many moving parts. In this work, we analyze the feasibility of using inflatable de-orbit devices that are triggered passively when a spacecraft is tumbling. Inflatables have already been proposed as hypersonic deccelerators that would carry large payload to the Martian surface. However, these systems are quite complex and need to withstand high-forces, temperature and enable survival of a critical payload. Furthermore, inflatables have been proposed as communication antennas and as structures using a class of sublimates that turn into gas under the vacuum of space.
