Elektrohydraulické aktuátory v letectví

Abstract

This bachelor thesis provides a comprehensive overview of electrohydraulic actuators (EHA) in aviation. Through literature review, it maps the development and current state of actuation systems, focusing on servohydraulic, electromechanical, and electrohydraulic actuators. It analyzes in detail the technical principles and various configurations of EHA. Furthermore, the thesis compares electrohydraulic actuators with alternative technologies and identifies specific technical and design challenges associated with their operation in aviation. A significant outcome is the creation of a model methodology for the preliminary sizing of EHA, including the derivation of basic analytical relationships and the creation of a mass model.
