Title:MultidisciplinaryDesignOptimizationofHybridAirshipsforAerostaticandAerodynamicLift
1.Introduction:
Inrecentyears,therehasbeengrowinginterestinthedevelopmentofhybridairshipsthatcombinebothaerostaticandaerodynamiclifttoachieveimprovedperformanceandversatility.Thispaperaimstoexplorethemultidisciplinarydesignoptimizationofsuchhybridairships,withafocusonmaximizingtheirliftingcapabilities,maneuverability,andefficiency.
2.Background:
Ahybridairshipisanovelaircraftthatutilizesacombinationofaerostaticlift,generatedbyalighter-than-airgas,andaerodynamiclift,generatedbytheairflowovertheaircraft'swingsorotherliftingsurfaces.Thisblendingofliftmechanismsallowstheairshiptoadapttovaryingaltitudeandwindconditions,makingitsuitableforawiderangeofapplications,includingcargotransportation,surveillance,andtourism.
3.DesignObjectives:
Theprimarygoalofthisoptimizationstudyistomaximizetheoveralllift-to-dragratio(L/D)ofthehybridairshipwhileensuringadequatemaneuverabilityandoperationalefficiency.Thiswillinvolveconsideringmultipledesignvariables,includingairshipshape,wingconfiguration,propulsionsystem,gastype,andballastsystem.Theoptimizationprocesswillbeconductedusingamultidisciplinaryapproach,consideringdisciplinessuchasaerodynamics,structures,materials,andpropulsion.
