PhD Student Benefits from NWTF Researcher Mobility Scheme

Access through the NWTF Researcher Mobility Scheme enabled Miguel Escudero Munoz, a joint PhD student at Cranfield University the Royal Military Academy, Belgium, to carry out advanced experimental research at City St George’s, University of London, using the Transonic Wind Tunnel.

The study aimed to improve the experimental characterisation of small-calibre projectile aerodynamics, a critical step for accurate ballistic modelling. Transonic results are highly sensitive to measurement techniques, making precise data essential.

Three model scales were tested at three angles of attack, covering transonic Mach numbers (0.7–1.0) and a supersonic case (Mach 1.5). Forces and moments were measured using a 5-DOF balance, while high-speed Schlieren imaging captured unsteady flow interactions. The Schlieren sequences were analysed using modal decomposition to link flow features with measured aerodynamic responses.

The scheme allowed Miguel to test larger model scales and study detailed flow behaviour under conditions that would not have been achievable otherwise, providing valuable insight into scale effects and aerodynamic performance.
