This procedure was developed and used to provide laboratory measurements of spool valve overlap and ports opening timing in the framework of hydraulic servomechanism SMHR qualification tests, in the ‘80s.
This work deals with structural stability analysis of straight beams, having different boundary conditions. The particular case of the beam on elastic foundation is also analyzed. The method of analysis is an approximate...
The article presents a mathematical modeling of aileron actuation that uses piezo V-shaped stacks. The aim of the actuation is the increasing of flutter speed in the context of a control law, in order to widen the flight...
Preventing overloads in wind tunnel model supports is crucial to the integrity of the tested system. Results can only be interpreted as valid if the model support, conventionally called a sting remains sufficiently rigid...
The paper deals with the mathematical and numerical modeling of the aerodynamic noise generated by the fluid flow interaction with the solid structure of a rotor blade.
Our analysis use Lighthill’s acoustic analogy. Lig...
