Affordable modal testing : An abstract GVT system
Autor: Louw H. van Zyl, Becker van Niekerk
Publikováno v: 2019 16th International Bhurban Conference on Applied Sciences and Technology (IBCAST).
The requirements for modal testing of aircraft structures are not demanding in terms of frequency range, size or weight of sensors, or power required to perform the tests. Yet typical ground vibration test (GVT) systems used for this purpose are expe

T-tail flutter: Potential-flow modelling, experimental validation and flight tests
Autor: Joseba Murua, Hector Climent, Louw H. van Zyl, Rafael Palacios, Pablo Martínez
Publikováno v: Progress in Aerospace Sciences. 71:54-84
© 2014 Elsevier Ltd.Flutter of T-tail configurations is caused by the aeroelastic coupling between the vertical fin and the horizontal stabiliser. The latter is mounted on the fin instead of the fuselage, and hence the arrangement presents distinct

Hybrid Finite-Volume Reduced-Order Model Method for Nonlinear Aeroelastic Modeling
Autor: Andrew Gavin Bradford Mowat, Louw H. van Zyl, Arnaud G. Malan, Josua P. Meyer
Publikováno v: Journal of Aircraft. 51:1805-1812
A fully coupled partitioned fluid–structure interaction technology is developed for transonic aeroelastic structures undergoing nonlinear displacements. The Euler equations, written in an arbitrary Lagrangian–Eulerian coordinate frame, describe t

Unsteady Panel Method for Complex Configurations Including Wake Modeling
Autor: Louw H. van Zyl
Publikováno v: Journal of Aircraft. 45:276-285
The calculation of unsteady air loads is an essential step in any aeroelastic analysis. The subsonic doublet lattice method is used extensively for this purpose because of its simplicity and reliability. The body models available with the popular imp
