Comparison of Flutter Analysis Approaches in the Frequency Domain for the ECL5 Open Fan

Abstract The topic of this paper is the flutter analysis at part speed of the ECL5/Catana open fan. The focus is on the operating point of maximal pressure ratio on the 80% speed line, where previous studies have revealed a very high sensitivity of the aerodynamic damping for the...

Mitigating aviation’s environmental impact through alternative fuels and cleaner engines

Lean-burn engines are designed to reduce emissions, and sustainable alternative fuels provide additional potential for lowering particle emissions. However, the magnitude of the benefits from these mitigation levers remains poorly constrained, limiting robust predictions of aviat...

Passive Back-Support Exoskeletons Reduce Cumulative Spinal Loading During Aeronautical Tasks

Effects of passive back-support exoskeletons (BSEs) on internal spinal loading during aeronautical tasks remain unclear. We quantified changes in L5/S1 compression force while 19 male participants performed representative aeronautical polishing and handling tasks (sustained flexe...

Leveraging existing electric propulsion capabilities for the Emirates Mission to the Asteroid Belt

The Emirates Mission to the Asteroid Belt (EMA), scheduled for launch in 2028, will conduct an eight-year, multi-target tour of seven main-belt asteroids, requiring over 10 km/s total delta-v and operations out to 3 AU. To meet these demands, the Laboratory for Atmospheric and Sp...
