Development of an Aeroprediction Method for Slender Bodies Including Aeroelastic Effects Using Euler-Based Local Piston Theory

Meijer, Marius-Corne (University of Pretoria, 2019)

Euler-based local piston theory (LPT) has received significant interest in recent literature. The method utilizes a simple, algebraic relation to predict between perturbation pressures directly from local surface deformation ...
Generalized formulation and review of piston theory for airfoils

Meijer, Marius-Corne; Dala, Laurent (American Institute of Aeronautics and Astronautics, 2016-01)

The present work presents a brief review of some of the notable contributions to piston theory and of its theoretical basis. A generalized formulation of piston theory is given, applicable to both local and classical ...
Local piston theory as an alternative to mesh deformation : slender wing/body configurations

Meijer, Marius-Corne; Dala, Laurent (American Institute of Aeronautics and Astronautics, 2018)

The suitability of local piston theory for modeling static loads on a deforming low-aspect-ratio wing in the presence of aerodynamic interference is investigated. Predictions using Euler-based local piston theory are ...
Quantifying nonlinearity in planar supersonic potential flows

Meijer, Marius-Corne; Dala, L. (Cambridge University Press, 2017-03)

An analysis is presented which allows the engineer to quantitatively estimate the validity bounds of aerodynamic methods based in linear potential flows a-priori. The development is limited to quasi-steady planar flows ...
Role of higher-order terms in local piston theory

Meijer, Marius-Corne; Dala, Laurent (American Institute of Aeronautics and Astronautics, 2019-02)

The use of second- and third-order classical piston theory (CPT) is commonplace, with the role of the higher-order terms being well understood. The advantages of local piston theory (LPT) relative to CPT have been ...
Zeroth-order flutter prediction for cantilevered plates in supersonic flow

Meijer, Marius-Corne; Dala, Laurent (Elsevier, 2015-08)

An aeroelastic prediction framework in MATLAB with modularity in the quasi-steady aerodynamic methodology is developed. Local piston theory (LPT) is integrated with quasi-steady methods including shock-expansion theory ...
