NTU Singapore's eVTOL aircraft successfully flew to heights above 90 meters and speeds of over 120 km/h, generating critical data on its performance. The aircraft demonstrated its ability to hover, fly using its fixed wings, and transition between modes, marking a milestone for Singapore's aerospace sector.
The University of Texas at Arlington (UTA) has been awarded a $1 million NASA grant to develop safety systems for drones and unmanned flying vehicles. The project aims to create an adaptive safety assurance architecture through extensive simulations and experimental testing, making future advanced air mobility vehicles smarter and safer.
Studies investigated the effect of trailing-edge fringes on owl wings, finding reduced noise levels and maintained aerodynamic performance. The simulations revealed two complementary mechanisms: reducing airflow fluctuations and suppressing feather interactions, leading to improved low-noise fluid machinery applications.
Researchers at Chalmers University of Technology have developed a propeller design optimisation method that paves the way for quiet, efficient electric aviation. The new design can reduce noise emissions by up to 5-8 dBA, comparable to going from a normal conversation voice to a quiet room.
Researchers from Tokyo University of Science developed a computationally quick approach to predict molten droplet solidification on a solid surface. The model simulates the solidification process by considering the droplet behavior and heat transfer between the hotter droplet and cooler surface, replicating experiments with high accuracy.
