However, most photoelectronic devices on spacecraft are rigid devices now, because the space environment consists of irradiations and thermal cycling, with higher requirements for flexible photoelectronic materials and devices. The main bottlenecks include: the synthesis of space-durable packaging materials, the fabrication and packaging of flexible photoelectronic devices, and the effective investigation method for irradiation mechanism analysis. In view of these problems, this review presents the synthesis of bulk-phase silicon-reinforced yellow and transparent polyimides with space durability, the optical modulation of bulk-phase silicon-reinforced polyimide to ultra-black film and flexible color filters, the electrical modulation of bulk-phase silicon-reinforced polyimide into flexible transparent electrode, the integration of the bulk-phase silicon-reinforced transparent polyimide and flexible triple-junction GaAs thin-film solar cell, and the exploration of general investigation methods for irradiation mechanism based on the penetration depth and damage modes including atomic oxygen, ultraviolet, electron, proton, and thermal cycling. The material synthesis, device fabrication, and mechanism analysis method focus on the core scientific problems of space-durable flexible lightweight photoelectronic materials and devices, leading the development direction of flexible and lightweight space science and technology.</p></div>","PeriodicalId":54553,"journal":{"name":"Progress in Aerospace Sciences","volume":"139 ","pages":"Article 100901"},"PeriodicalIF":9.6,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47412472","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}

Advancements such as transatlantic flight and the development of avionics technologies and composite materials have changed how we think about what the future will hold. Advanced aviation technologies such as remotely piloted aircraft systems (i.e., “drones”) and urban air mobility may be the next revolution in the aviation industry. While many in the aviation industry look forward to greater inclusion of these technologies, the public may have a different perspective. This review aims to examine the factors that may influence one's perception of advanced aviation technologies. First, an overview of the technologies is presented to categorize the different types of drones and how they are used, followed by a discussion on the principles of technological adoption. Next, data from past studies investigating the public perception of drones and air taxis was collected and analyzed to discover if any patterns exist in terms of overall acceptance or mission preferences, and to determine the root causes of hesitancy towards this emerging technology. The trends suggest that drones have become increasingly accepted as public awareness rises, and missions that support the common good are viewed more favourably than commercial uses such as package delivery or air taxi services. The major obstacles include the perceived level of risk, pre-existing judgement as to the technological reliability, as well as the lack of perceived benefits when compared to existing technologies. Each of these topics are discussed and finally, a roadmap towards public acceptance is presented, incorporating the viewpoints of the public, drone users, and regulatory authorities. Together, this review discusses the current state of the field and what must be done to better integrate advanced aviation technologies into everyday life.</p></div>","PeriodicalId":54553,"journal":{"name":"Progress in Aerospace Sciences","volume":"138 ","pages":"Article 100899"},"PeriodicalIF":9.6,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44511452","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}

Aircraft currently in operation have typically been designed by considering the airframe somewhat separately from the propulsion system. In doing so, conventional aero-engine architectures are approaching their limits in terms of propulsive efficiency, with technological advancements yielding diminishing returns. A promising alternative architecture for improving the overall performance of the next generation of commercial aircraft relies upon boundary layer ingestion (BLI). This technology aerodynamically couples the airframe with a strategically positioned propulsion system to purposely ingest the airframe’s boundary layer flow. Nonetheless, there is a lack in consensus surrounding the interpretation and quantification of BLI benefits. This is primarily because conventional performance accounting methods breakdown in scenarios of strong aerodynamic coupling. Subsequently, there is a major challenge in defining appropriate performance metrics to provide a consistent measurement and comparison of the potential benefits. This review examines the various accounting methods and metrics that have been applied in evaluating BLI performance. These are discussed and critiqued in the context of both numerical and experimental models. Numerically, the geometric, aerodynamic and propulsive models are sorted by their orders of fidelity along with the plenitude of methods used for flow feature identification enabling a phenomenological understanding of BLI. Particular attention is then given to experimental BLI models with their different set-ups, methods and associated limitations and uncertainties. Finally, the numerous unconventional BLI aircraft concepts are categorised, compared and critiqued with reference to their associated design exploration and optimisation studies.</p></div>","PeriodicalId":54553,"journal":{"name":"Progress in Aerospace Sciences","volume":"138 ","pages":"Article 100897"},"PeriodicalIF":9.6,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47913167","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}

Aviation is not an exception. Despite the overall carbon dioxide emissions related to the aviation sector accounts for 2%–4% currently, forecasts for air travel indicate an annual growth of 3%–5% and other industries present more potential to reduce carbon emissions once they recur to an increasing use of renewable energies. This option is more difficult in aeronautics since an efficient and lighter energy storage system is required and the current state of the art in battery technology is far from the specific energy densities of fossil fuels and its production is not friendly to the environment. Thus, a herculean effort to integrate several promising mitigation strategies in an efficient way is required. In this paper, a review of the most upfront solutions towards greener aviation is presented and categorized as follows: concepts of operations, energy storage, propulsion systems, aerodynamics, structures, materials, and manufacturing processes.

The combination of lower launch costs, reduced radiation effects, and ease of deorbit, among other benefits, outlines very low Earth orbit (VLEO) missions as a key prospect of the space sector in the near future.&lt;/p&gt;&lt;p&gt;Neutral atomic oxygen (ATOX), the dominant gas species in lower orbital altitudes, is a major consideration for VLEO missions. The oxidising nature of ATOX with relative speeds at least 7.8 km/s can easily cause an early end to a satellite mission through generation of drag forces, as well as degradation of solar array surfaces and optical instruments. During a mission, accurate quantification of this erosion damage aboard the spacecraft may be gained though gathering data regarding ATOX gas flux impinging on susceptible surfaces at a given point in time.&lt;/p&gt;&lt;p&gt;Additionally, increased aerodynamic loading, caused by greater gas densities at lower altitudes, plays a substantial role in satellite station keeping and attitude control; an aerodynamically unstable spacecraft may experience undesirable rotational forces or even enter a tumbling state if left unchecked. Real-time measurement of ATOX flux allows a mission to determine short-term variations in ATOX flux and therefore estimate fluctuations of satellite lift and drag, enabling a satellite to react appropriately. Long-term recording of these fluctuations may also hold influence over future satellite aerodynamic design.&lt;/p&gt;&lt;p&gt;Atomic oxygen sensing methods are a crucial aspect of future VLEO satellite design as we begin to tackle the obstacles of reduced altitude orbits. These sensors are able to measure the quantity of atomic oxygen atoms impinging on a satellite per unit area. In the interest of reacting to, and designing for the erosive environment and aerodynamic forces presented by ATOX and gas species in VLEO, we review available ATOX sensing methods and their respective applications.&lt;/p&gt;&lt;p&gt;Each ATOX sensing method has its own benefits and drawbacks. The most appropriate method for a given mission depends on factors such as altitude, mission lifetime, and mass budget.
