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.</p><p>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.</p><p>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.</p><p>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.</p><p>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. A review of the most common methods will clarify design options, and outline suitable areas for future research.</p><p>This paper builds upon a review of ATOX measurement methods performed by Osborne, et al. in 2001, updating with technologies from the past two decades as well as providing further examples of each method’s real-world applications.</p><p>It also conducts a semiquantitative analysis of spacecraft-based atomic oxygen sensing methods, describing the relative merits of each and their relevant applications.

As a carbon-neutral alternative and intended drop-in fuels, SAFs would be an appropriate path forward for sustainable aviation. Current approved drop-in fuels enable 50% blending of SAFs, which decreases CO₂ emissions up to 40%. However, CO₂ emissions can be reduced much further by using 100% SAFs or hydrogen. Comprehensive analysis of SAFs in terms of their operational performance, impact on gaseous and particulate emissions, seal swell, engine and fuel systems compatibility, blow-off limits, ignition and relight, vibrations, and noise is essential to move towards 100% SAFs. Furthermore, SAF has been demonstrated to reduce other emissions like NOx, particulate and CO₂ emissions subjective to the fuel production pathways. Therefore, engineering novel fuels and innovative production pathways may lower emissions and reduce the costs of aircraft system design and operation, resulting in cheaper air travel. This study thoroughly examined and discussed all the aspects mentioned above. Hydrogen, a potential competitor for SAFs, has also been analyzed in this study in terms of future production capability to meet aviation needs and the impact of hydrogen combustion on design changes, emissions, and fuel systems. Furthermore, to reduce experimental costs related to SAFs, this study explored approaches for modeling and predicting novel fuel performance in the preliminary stages of fuel assessment.</p></div>","PeriodicalId":54553,"journal":{"name":"Progress in Aerospace Sciences","volume":"136 ","pages":"Article 100876"},"PeriodicalIF":9.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47196514","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}
