Single-Point and Multipoint Design of Propellers for Electric-Powered General Aviation (2024)
Journal Article
Sugar-Gabor, O. (in press). Single-Point and Multipoint Design of Propellers for Electric-Powered General Aviation. Journal of Aerospace Engineering, https://doi.org/10.1061/JAEEEZ/ASENG-5718

With electric-powered aircraft concepts slowly maturing, it becomes feasible to include RPM regulation in propeller operation. Variable-pitch and variable-speed propellers will be designed for efficient operation in a wider performance space compared...

A neural network based non-intrusive surrogate modelling framework for fluid-structure interaction (2024)
Journal Article
Fairchild, D., & Şugar-Gabor, O. (in press). A neural network based non-intrusive surrogate modelling framework for fluid-structure interaction. International Journal of Multiphysics, 18(3),

The use of surrogate modelling in Multiphysics simulation is becoming increasingly attractive due to large computation time and hardware demands of modern simulations. These methods aim to reduce the computational time and complexity of the determina...

An optimisation of a chordwise slot to enhance lateral flow control on a UCAV (2022)
Journal Article
Ali, U., Chadwick, E., & Sugar-Gabor, O. (2022). An optimisation of a chordwise slot to enhance lateral flow control on a UCAV. Incas Bulletin, 14(4), 3-17. https://doi.org/10.13111/2066-8201.2022.14.4.1

This research aims to optimise a chordwise slot so that lateral flow control of a flying wing
configuration can be enhanced. This was achieved by maximising the airflow rate over the trailing edge
control surfaces of the wing. A higher rate of airf... Read More about An optimisation of a chordwise slot to enhance lateral flow control on a UCAV.

Active flux scheme for time-dependent, viscous, compressible flows (2022)
Presentation / Conference
Sugar-Gabor, O. (2022, October). Active flux scheme for time-dependent, viscous, compressible flows. Presented at International Conference of Aerospace Sciences AEROSPATIAL 2022, INCAS, Bucharest, Romania

The Active Flux scheme is a Finite Volume scheme with additional degrees of freedom on the cell
boundaries. These additional nodes allow for third-order accuracy to be achieved, though extensions to
higher orders are also possible. Unlike Godunov-t... Read More about Active flux scheme for time-dependent, viscous, compressible flows.

Non-intrusive reduced-order model for unsteady fluid flow and fluid-structure interaction problems (2022)
Presentation / Conference
Sugar-Gabor, O., & Fairchild, D. (2022, October). Non-intrusive reduced-order model for unsteady fluid flow and fluid-structure interaction problems. Presented at International Conference of Aerospace Sciences AEROSPATIAL 2022, INCAS, Bucharest, Romania

A non-intrusive reduced-order model applicable to time-dependent parametric systems is
developed. The model is based on extracting a reduced-order basis from high-order snapshots via proper
orthogonal decomposition. Multi-layered feedforward artifi... Read More about Non-intrusive reduced-order model for unsteady fluid flow and fluid-structure interaction problems.
