ALLGO, Inflatable Moon Crane (IMC), 16 42 inch inflatable tubes · 模型 267484
Inflatable Moon Crane (IMC) that can lift the highest loads (11000kg) with the biggest diameters (8 meter). With 2 meter headspace under the load! Structurally sound, all forces are calculated and accounted for! This is my design it can be packed in the smallest NASA module designed to go to the moon: the 8.4 meter USA. The capsule also packs 2 big containers, one battery and one air tank with a volume of 9383 liter. If the air tank is pressurized to 250 bar that would come down to 2.345 ML or 2,873 kg of air. All the inflatables need only need 714,061 Liter (or 0.71ML) to fully inflate, so that is some extra air for the crane. I ran the program (PressArchAnalysis) that was used in the "Feasibility of a Self-Erecting Shelter with an Inflatable-Fabric-ArchSupported Roof and Rigid Walls" file mentioned in the comments by Kevin Kempton. The calculations showed that one 42 inch inflatable arch of 22 meters wide, reinforced with 100mm wide 10mm high straps, could hold 0.8 times the weight of 11 Metric Ton on the moon. So lifting 11 Metric Ton on the moon could be done with 2 arches, but that would be in a static situation. When its moving all sorts of dynamic forces would also act on the inflatables. And id better fill up as much cargo capacity as i can because wasting space is a real big shame when it costs so much to lift things into space, especially when i has to go to the moon. So 16 beams in total. That should hold itself. 8300 lb/in was used as fabric strength in the calculations with the program. Also the 8 meter diameter as mentioned in this link: https://www.herox.com/LunarDelivery , was something i wanted to design around. So using all the cargo space (on the floor) wasnt such a bad idea. The arches are tied with cables so there wont be any forces trying to push the arches outwards. That is a big concern when using arches, so that is why i think my design is pretty solid. There are 2 tie arches that go on both sides of the wheels, that way the wheels wont be pulled inward or outward. Ensuring the crane will stay on its feet. There is a platform with a crane in the middle of the arches. The arches are connected to the carts and platform through the use of bulkheads and clevises. "Review of Habitable Softgoods Inflatable Design, Analysis, Testings, and Potential Space Applications, page 8." The crane can move 1.8 meter to each side by a trolley on a track. 3.6 meter total movement. It is based on a tower crane. So it should have enough li...
