1.Introduction
Thedemandforairshipshasbeenincreasingduetotheirversatility,lowoperationalcosts,andeco-friendliness.However,thehighcostofairshipgondolashasbeenalimitingfactorforwidespreadadoption.Thispaperproposesalow-costdesignforanon-pressurizedcompositeairshipgondolathatreducestheoverallcostwhilemaintainingsafetyandperformancerequirements.
2.DesignProcess
Thedesignprocessinvolvedconceptualization,preliminarydesign,detaileddesign,andfinalization.Themainconsiderationsincludedweightreduction,structuralintegrity,andeaseofmanufacturing.Computer-aideddesigntoolswereusedtomodelandsimulatethecomponents,ensuringoptimalperformanceandstability.
3.StructuralAnalysis
Finiteelementanalysis(FEA)wasemployedtoevaluatethestructuralintegrityofthegondola.Variousloadingconditions,suchasstatic,dynamic,andaerodynamicloads,wereappliedtoassessitsstrengthandstability.Stress,deformation,andfailurecriteriawereanalyzedtoensuresafetyduringoperationalconditions.
4.ManufacturingTechniques
Toachievelow-costfabrication,acombinationofhandlay-upandvacuuminfusiontechniqueswasused.Theuseoflow-costmaterials,suchasfiberglassandcarbonfiber,furtherreducedtheoverallcostwithoutcompromisingstructuralintegrity.Attentionwaspaidtooptimizingthemanufacturingprocesstomaximizeefficiencyandminimizewaste.
