These aerodynamic phenomena are collectively known as tip flow unsteadiness. It has been proven that tip flow unsteadiness not only serves as an excitation source of both non-synchronous vibration and tip noise but is also the cause of short-length-scale stall inception. These structural and aerodynamic problems have become common issues in highly loaded axial compressors, which require a breakthrough in the study of tip flow unsteadiness. This article begins with a review of past research on unsteady tip flow phenomena, examining them from the perspectives of self-excited unsteadiness and rotating instability (RI). Detailed discussions are presented on the relationships between RI and tip clearance noise, non-synchronous vibrations, and stall inceptions. This is followed by explanations for the origin of the tip flow unsteadiness. Six theories proposed in existing literature are classified, including vortex shedding, tip leakage vortex breakdown, the interaction between tip leakage flow and adjacent flow, rotating instability vortex, tip secondary vortex, and shear layer instability. There have been only limited investigations of control techniques aimed at suppressing tip flow unsteadiness. These methods are classified according to their control mechanisms and the corresponding control effects are presented. Additionally, recommendations for future advancements in these fields are presented.</div></div>","PeriodicalId":54553,"journal":{"name":"Progress in Aerospace Sciences","volume":"152 ","pages":"Article 101063"},"PeriodicalIF":11.5,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depending on the flight distance and speed, some carbon-neutral aircraft types demand less renewable electricity, while others are infeasible. Previous work focuses on the cost and climate impact of these alternative fuels and their effects on individual aircraft designs, but not when each solution is viable.

To make progress towards sustainable aviation, it is necessary to synthesize a definition for sustainable aviation from the key elements of aviation and sustainability. <strong>Sustainable aviation is the process of creating the air transportation system that maintains the connectivity of communities and mobility of people, goods, and services while minimizing negative impacts to human health, fostering productive quality of life, and conserving natural resources.</strong> We then apply this definition to create a theoretical framework, the Five Circles of Sustainable Aviation, which can be utilized to establish sustainability goals for the broad aviation ecosystem. We then apply the theoretical framework to the sustainability of contemporary and concept aircraft. We provide an example sustainability metric analysis that subdivides the Five Circles of Sustainable Aviation into a series of preliminary, illustrative, quantitative and qualitative metrics that can be used to assess aviation systems for their sustainability performance. The importance of applying this framework within a system-of-systems perspective of the aviation value stream is emphasized, with can be used for the practical development of engineered systems pursuant to these sustainability goals. We also address the effects of our definition and sustainable aviation perspective to governance, education, regulation, and safety.

The study and comprehension of compressible vortex loops and their interactions have historically relied heavily on optical techniques, lacking comprehensive insight into the intricate flow dynamics. Nevertheless, the advancements in flow visualisation tools and computational capabilities in the 21st century have significantly aided scientists in scrutinising and characterising these vortex loops and their interactions in intricate detail.

First, the control theories and methods related to launch vehicles are classified and surveyed. Although studies in this field are still active, many new methods have not exhibited impressive advantages over a well-tuned gain scheduling-based traditional solution when dealing with a complete rigid–flexible-sloshing model, and few have been adopted for in-flight use. The conservatism in applications stems from the distinctive dynamical characteristics of launch vehicles, which are discussed in detail thereafter. However, as traditional methods also face challenges in meeting the increasing new requirements, an innovative solution, namely RTC, has gradually found its role in robust launch vehicle applications. The RTC differs from the concept of adaptive control in that it has no effect under most conventional operations but responds to certain scenarios in a timely manner, and these scenarios include unmodeled modes, unforeseen disturbances far beyond prescribed limits, and unexpected failures where the fundamental assumptions implied in the feedback control theories or design guidelines are violated. After introducing a practical architecture of RTC, three methods are reviewed and their limitations are analyzed: an adaptive gain and damping adjustment method to deal with unmodeled modes, an angular-acceleration-based active load-relief method to reduce bending moments, and online identification and reconstruction of the command mapping relationship to counter the polarity errors. The RTC introduced in the paper has been validated from an applied and computational domain by flights or simulations with high fidelity, thus effectively improving the robustness and the adaptability of launch vehicles.</p></div>","PeriodicalId":54553,"journal":{"name":"Progress in Aerospace Sciences","volume":"149 ","pages":"Article 101028"},"PeriodicalIF":11.5,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141945336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
