At least that\u2019s what Washington State University researchers are hoping after they harnessed the ancient art of origami to develop a foldable fuel bladder that stands up to cryogenic temperatures.<\/p>\n<p>Graduate student Kjell Westra, engineering professor Jake Leachman and their colleagues at WSU\u2019s Hydrogen Properties for Energy Research Laboratory, or HYPER Lab, describe their design in the journal Cryogenics. Their research addresses a longstanding challenge in rocket science: How can you store and pump super-chilled propellants like liquid hydrogen more efficiently?<\/p>\n<p>\u201cFolks have been trying to make bags for rocket fuel for a long time,\u201d Leachman said today in a news release. \u201cWe currently don\u2019t do large, long-duration trips because we can\u2019t store fuel long enough in space.\u201d<\/p>\n<p>During the early days of the space effort, engineers tried to develop balloon-style bladders for managing the storage and flow of liquid hydrogen, Unfortunately, such bladders were prone to shatter or leak when they were squeezed. The hardiest designs could survive only five cycles of squeezing and relaxing.<\/p>\n<p>Current systems use metal plates and surface tension to manage fuels, but researchers are still searching for more efficient systems.<\/p>\n<p>When the WSU researchers looked through the literature, they came across research that described the development of a bellows that took advantage of origami, the Japanese art of paper-folding. The research discussed applications relating to medical stents, or even deployable solar sails for spaceflight \u2014 but Westra and his colleagues adapted the design for rocket fuel bladders.<\/p>\n<p>\u201cThe best solutions are the ones that are already ready-made and that you can then transfer to what you\u2019re working on,\u201d Westra explained.<\/p>\n<p><iframe title=\"Origami Bellows: Interview with Kjell Westra\" src=\"https:\/\/www.youtube.com\/embed\/W8FKYcxZYhk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" data-ratio=\"0.5625\" data-width=\"800\" data-height=\"450\" style=\"display: block; margin: 0px; width: 800px; height: 450px;\"><\/iframe><\/p>\n<p>It took a few tries \u2014 and some guidance from a YouTube video \u2014 to figure out how to fold thin sheets of plastic into the desired configuration. Once Westra mastered the technique, he tested the origami bellows in a vat of liquid nitrogen cooled to a temperature of about 77 Kelvin (320 degrees below zero Fahrenheit).<\/p>\n<p>The researchers hoped that the origami folds would spread out the stresses on the plastic material, making it less likely to tear \u2014 and their hopes were borne out by the experiments. Their intricately folded bladder could be squeezed at least 100 times under cryogenic conditions without breaking or leaking.<\/p>\n<p>\u201cWe think we\u2019ve solved a key problem that was holding everybody back,\u201d Leachman said. Now the researchers are getting set to conduct similar experiments with liquid hydrogen, which has to be kept at even colder temperatures \u2014 20 Kelvin, or 423 degrees below zero F.<\/p>\n<p>Westra has been awarded a NASA graduate fellowship to keep working on the project. And that\u2019s not all: The work has received funding from the Joint Center for Aerospace Technology Innovation, an economic development initiative backed by Washington state \u2014 as well as from Amazon CEO Jeff Bezos\u2019 Blue Origin space venture. \u201cKjell\u2019s success is a perfect example of great WSU students studying what\u2019s out there, and then being in the right place at the right time to make it happen,\u201d Leachman said.<\/p>\n<p><em>In addition to Westra and Leachman, the authors of the Cryogenics study, \u201cCompliant Polymer Origami Bellows in Cryogenics,\u201d include Francis Dunne, Stasia Kulsa and Mathew Hunt.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A plastic bladder folded into an origami shape can stand up to cryogenic temperatures.
