  This paper presents a part of the works conducted in the Plasmaero European project (task 1.1) on surface dielectric barrier discharge actuators applied to airflow control. The study is divided into several parts. In the first part, the goal is to enhance the electric wind produced by a typical single DBD actuator by optimization of the active electrode shape. For instance, the use of a thin wire instead of a plate air-exposed...

  Shape adjustment and stress control can be considered as one of the effective parameters in prestressed cable structures since such structures are widely constructed nowadays due to their characteristics. The assembly errors and applied loads hugely affect the cables’ nodal positions and stress due to their delicacy. The former could disturb the shape, which affects the appearance and the function of the structure. In contrast,...

  Traditional shape and stress control of structures use many actuators and require enormous time to find reasonable solutions that need designers to input specific target displacement and stress. This study employs a linear technique to static shape and stress control of pin-jointed assemblies as a theoretical advancement to prior works and provides a comparative analysis against previously established works. The study evaluates...

• Redundant Actuation of 3RRR over-actuated Planar Parallel Manipulator

  Publikacja

  • K. Lipiński

  - Rok 2009

  Praca opisuje zagadnienia modelowania i napędzania manipulatorów równoległych. Cechą charakterystyczną manipulatorów równoległych jest występowanie jednego lub kilku łańcuchów kinematycznych zamkniętych (gałęzi równoległych). Standardowo, konstrukcje takie są napędzane jedynie silnikami montowanymi w parach kinematycznych łączących łańcuchy kinematyczne z podstawą. Niekiedy konstrukcje takie są układami napędzanymi nadmiarowo (liczba...

  - Przegląd Elektrotechniczny - Rok 2012

  In this paper application of innovative multi-DBD plasma actuator for flow separation control is presented. The influence of the airflowgenerated by this actuator on the flow around NACA 0012 and NACA 0015 airfoil models was investigated. The results obtained from 2D PIVmeasurements showed that the multi-DBD actuator with floating interelectrode can be attractive for leading and trailing edge separation control.

  - ERCOFTAC Bulletin - Rok 2013

  In the framework of the PLASMAERO European project, experiments were conducted to investigate the authority of surface DBD plasma actuators to alter a fully separated flow around an airfoil in order to improve its aerodynamic performances in its natural stall regime. In this paper, unsteady excitation control is more specifically investigated. The key control parameter studied here is the burst frequency which periodically imposes...
