A variational approach is used to derive the first-order necessary conditions for optimality, which form the basis of our iterative direct-adjoint looping numerical solution algorithm. The method is demonstrated on an illustrative 2-state dynamical system that possesses key features of the incompressible Navier-Stokes equations. We then apply the method to analyze a reduced-order model of a sinusoidal shear flow at 𝑅𝑒 = 20 . Our results establish the power of the proposed optimization framework for revealing dominant modal interactions and sparse perturbation mechanisms for transient growth and instability in fluid flows.","PeriodicalId":403570,"journal":{"name":"AIAA AVIATION 2023 Forum","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115702961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over decades numerous researchers have found numerous factor that affects spacecraft lifespan as well as reliability. In this paper, we have defined three different spacecraft mass fraction parameters relative to the spacecraft’s dry mass, propellant mass, and payload. Thereafter, we have related the above-mentioned parameters to spacecraft lifespan and reliability. The result showed that the spacecraft mass fraction imposes a significant impact on satellite reliability thereby affecting its lifespan during the course of a mission. Following, we have hypothesized spacecraft mass fraction limit ideal for a durable mission. In addition to that, we have proposed some factors that play a major role in determining the reliability of spacecraft","PeriodicalId":403570,"journal":{"name":"AIAA AVIATION 2023 Forum","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116954560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
