COMPOSITEMATERIALS FORWIND POWER TURBINE BLADES


Abstract

Renewable energy resources, of which wind energy is prominent, are
part of the solution to the global energy problem. Wind turbine and the rotorblade
concepts are reviewed, and loadings by wind and gravity as important factors for
the fatigue performance of the materials are considered. Wood and composites are
discussed as candidates for rotorblades. The fibers and matrices for composites are
de ....etc

Abstract

This work features the design and a control scheme for an active multi-degree of freedom kinematic pair piezoelectric robot. We introduce the piezoelectric active kinematic pair where the joints between the links are made from piezoactive material. The objective is to design an energy efficient underactuated precision micromanipulator with a fault-tolerant design where not all joints require actuators. Typical configuration of this type of piezoelectric robot is that it consists of several identical joints, i.e. kinematic pairs of t ....etc

ACTIVE TWIST OF MODEL ROTAR BLADES WITH D-SPAR DESIGN.


ABSTRACT

The design methodology based on the planning of experiments and response surface technique has been developed for an optimum placement of macro fiber composite (MFC) actuators in the helicopter rotor blades. The baseline helicopter rotor blade consist of D-spar made of UD GFRP, skin made of +45/-45 GFRP, foam core, MFC actuators placement on the skin and balance weight. 3D finite element model of the rotor blade has been built by ....etc

Twist beam


Introduction:-
Twist beam cross member was found failing in field having covered around 34392 Km and was sent for
failure investigation.
Material Observations: - Refer attached Sheets for details.

Remarks:-
1) Material and properties of cross member conforms toE46.
2) Sample has failed near the bracket welding on LH side.
3) Notch like marks as seen on earlier were observed in failed sample indicating unevenness of the plate

Worn area modeling for automating the repair of turbine blades


Abstract
The current repair process for worn-out turbine blades and blisks is very manual, and experience based and hence is error prone. It requires sophisticated CNC-driven (Computer Numerical Control) laser equipment to replace manual welding for the repair. This paper presents an innovative strategy that can lead to the automation of laser welding and cladding. The project makes use of reverse engineering techniques to capture the geo ....etc
