Lecture in English

The Aeroshark riblet film imitates the shark skin effect and causes a noticeable drag reduction, which is equivalent to one percent of saved fuel based on a typical long-haul flight. This lecture gives insight into the development of Aeroshark for the Boeing 777 from an aerodynamic perspective.

Riblets reduce losses from interaction of microscopic vortices with the wall. This beneficial effect is integrated into the CFD model using extensions of the commercial solver Ansys CFX, which allows the investigation of large-scale models like an entire aircraft. The turbulence model modified for the riblet effect was verified by experimental results from DLR and DNW.

Many secondary effects became visible due to changes in the boundary layer thickness when the entire flight envelope was investigated. Hence, for certification, effects on flight characteristics, structural integrity and functionality of aircraft systems had to be considered.

Dedicated flight tests for aircraft stability and control were performed with special test programs, because here numerical tools usually show only low confidence. The enhanced fuel saving analysis is based on full flight data in contrast to single snap-shots as in standard aircraft performance monitoring. A problem is the uncertainty in total passenger mass due to the unknown mass of each individual passenger. However, an alternative approach for weight determination has been used, which is based on attitude sensors of the aircraft and reduces the uncertainty of the aircraft weight. This significantly improves the confidence of the drag analysis process.

F-35B. National Museum of the U.S. NavySystems Engineering is a diverse field both in terms of approaches but also in impact and exploitation. Working across 12 political systems, with over 700 aircraft operational worldwide, the F-35 is a 5th Generation military aircraft which delivers impact through data. Keeping all the software intensive systems flying, through obsolescence, repair, new technology and upgrade is a configuration and logistical challenge. In late 2019, the US F-35 Joint Project Office embraced agile software delivery to reduce software cycle times from 18 months to 6 weeks. This is the story of that time.

 

About Dr. Gill

Kate Gill has 20 years international experience of Systems and Software Engineering, Management and Consultancy in both the Defence and Civilian markets. From 2016 – 2022, she was seconded from the Ministry of Defence to be the US lead Air Systems Integrator, based in Washington DC, for all UK software engagement on the military aircraft F-35. She has led and championed digital transformation within the Department of Defense (DoD) F-35 Agile DevSecOps (DSOP) ecosystem. Kate has been the driving force for the stand-up of the US F35 Joint Project Office (JPO) Managed Cloud which enables software on the +625 F-35 aircraft worldwide. Kate was awarded the Royal Aeronautical Society Silver Medal in 2021 and was Women in Defence Most Collaborative Award Finalist in 2020 and 2022.

 

She has stayed in the Civil Service and has now moved out of Defence into a digital role supporting biodiversity research at Kew Gardens as Digital Revolution Lead.
