Distributed Hybrid-Electric Propulsion Benefits for Span-Limited Aircraft

The impact of the ICAO code C gate span limit is assessed on the sizing of a serial Hybrid Electric Aircraft (HEA) of increasing Degree of Hybridization (DoH). For a set of Top Level Aircraft Requirements (TLARs) similar to the ATR-42, it is shown that the increase in MTOM due to the presence of the battery is such that only a maximum DoH under...

Mapping the Sandy Beach Evolution Around Seaports at the Scale of the African Continent

In Africa, several new seaport developments are being considered. In sedimentary environments, such port developments can have adverse impacts on the evolution of adjacent coastlines. To learn from past port engineering practice, we created a unique database containing the coastline evolution and characteristics of 130 existing African seaports....

Diffusion of a mega feeder nourishment: Assessing 5 years of Sand Engine spreading

Feeder nourishments, where sand quantities of O (10 million m³) are placed locally to feed adjacent coastal stretches, are suggested nowadays as an alternative for local, smaller-scale nourishments (< 1 million m³). These feeder nourishments rely on natural forces to spread the sediment. While processes that govern this spreading such as...
