It is active in the following areas: — Aeronautics and air transport; — Functional materials and nanotechnologies; — Technical diagnostics and non-destructive methods of control. Major projects: — Development of a prototype of an autonomous aerospace vehicle for comprehensive monitoring; — A novel concept of an extremely short take-off and landing all-surface hybrid aircraft: from a light passenger aircraft to a very high payload cargo/passenger version; — Development of an experimental long flight distance unmanned aerial vehicle prototype for multi-purpose environmental monitoring.POINTS OF EXCELLENCE REMOTELY PILOTED AIRCRAFTS AERTI 3 There is provided a remotely controllable airplane adapted for belly-landing, the airplane comprising a fuselage, a wing, a tail, a motor with a propeller, and an under-fuselage payload container adapted for carrying a surveillance equipment, wherein the payload container comprises a front module, an aft module, both coupled to the fuselage and spaced apart along the fuselage axis, and a central module, wherein the central module is rotatably attached to the front module and to the aft module. Remotely piloted aircrafts find wide application for military and civilian purposes when manned flight operations are unacceptably costly and/or dangerous.ACOUSTIC EMISSION STRUCTURAL HEALTH MONITORING TECHNOLOGY FOR MACHINERY AND BUILDING STRUCTURESDeveloped Acoustic Emission (AE) structural health monitoring (SHM) technology for machinery and building structures makes it possible to perform both the individual object elements and the whole object quality quantitative assessment in real structures in operation conditions. This technology can be used to evaluate SHM of such objects as building structures, bridges, aircrafts, watercrafts, including in operation. Developed AE method has a high sensitivity that is by far the most sensitive compared to other methods.INSTITUTE OF MATERIALS AND STRUCTURES Research directions: — Finite element modelling and analysis of sandwich and laminated composites and structures; — Optimal design of composite materials, structures and technological processes; — Identification of material properties and damage in advanced composites; — Damping analysis of composite materials and structures; — Fracture analysis of laminated composites; — Buckling and post-buckling modelling of stiffened composite structures; — Smart control by PZT and MFC; — Testing of material properties; — Experimental analyses: static, dynamic, fatigue, impact; — Experimental damage characterization in composite materials and structures. European Framework projects: — Advanced low cost aircraft structures; — Integration of technologies in support of a passenger and environmentally friendly helicopter; — Modular ship concepts; — Composites and adaptive structures: simulation, experimentation and modelling; — Improved material exploitation at safe design of composite airframe structures by accurate simulation of collapse; — Developing lightweight modules for transport systems featuring efficient production and lifecycle benefits at structural and functional integrity using risk based design; — Flexible and near-net-shape generative manufacturing chains and repair techniques for complex shaped aero engine parts.POINTS OF EXCELLENCE The researchers of the Institute of Materials and Structures of the Faculty of Civil Engineering in cooperation with company Airbus DS and the European Space Agency are developing a design and certification methodology, which can be used to determine the lowest robust load bearing capacity of thin-walled (radius/thickness ratio 400 to 1000) composite shells. The methodology will be used in manufacturing of the next generation of spacecrafts from composite materials. The aim of the research is to develop an efficient design methodology for composite spacecraft constructions, assessing geometrical imperfections. Cylindrical thin-walled shells are most sensitive to product geometric tolerances, therefore the research focuses on the development and validation of design and certification methodology, which can be used to determine the lowest reliable design bearing capacity of thin-walled composite shells.INSTITUTE OF INDUSTRIAL ELECTRONICS AND ELECTRICAL ENGINEERING Research directions: — Power electronic converters and their control algorithms in modern power supply systems, electric drive and renewable resource usage; — Smart electric technologies in lighting systems; — Manufacturing automation and energy efficiency improvement; — Smart electric transport systems.

Energy consumption reduction can reach up to 25% in a single robot production cell. Real 600V DC micro-grid architecture was implemented and compared with existing AC Grid technologies in DAIMLER AG factory in Sidelfingen, Germany. A simplified demo lab of a robotic factory production cell was set up in premises of RTU. — A measurement system for monitoring electrical energy consumption has been developed within the National Research Programme "LATENERGI". The system is suitable for synchronous energy flow measurements in large number of points and can be applied either in industrial or household environment. The prototype of the system has been approbated in two industrial test sites - “Daimler” (Germany), and “SIR” (Italy).POINTS OF EXCELLENCE SPECIALISED SYSTEM FOR COMPUTERISED CONTROL OF EMBEDDED DEVICES Effective public utility sector facilities management and control tasks require the embedded systems for assistance in the automated water supply, power supply and heat supply control and management.
