BLISK 1. BLISK or IBR (Integrated Blade Rotors) are among the most innovative and challenging components in modern gas turbine engines. BLISK may be integrally cast‚ machined from a solid piece of material or made by welding individual blades to the rotor disc. Initially BLISK was used only in first stage LP compressor. Its low weight and excellent aerodynamic efficiency making it popular for use in the HP stage also. CONVENTIONAL DISK Vs BLISK 2. Conventional rotor disk comprises rotor blades

Three major disasters struck Texas in the 20th century. They left both wonderful and unhelpful social‚ political‚ and economic effects. The Texas City Explosion had the most lasting effects on the US. Many people died in the explosion‚ and many more were injured. There were so many people that were injured‚ that the hospitals were overcrowded and the Red Cross had to put up field stations to help the injured. As Wanda Lou Baker wrote in Past Stories‚ many of the injured were put on the lawn. The

Mohammed Asif M et al studied the impact of heat input on tensile strength‚ toughness‚ micro hardness‚ micro structure and corrosion behavior of duplex stainless steel joints. Four parameters were varied by keeping speed as constant. The heating pressure of 30‚ 40‚ 50 MPa‚ heating time of 3‚ 4‚ 5 sec‚ upset pressure of 60‚ 70‚ 80 MPa‚ upset time of 2‚ 3‚ 4 sec were used to weld the joints. L9 orthogonal design concept was used. Results revealed that no intermetallic phases were formed. By increasing

Welding ¨Don`t be afraid of the future Build It.¨ Welding has taught that nothing is impossible if you work for it. At first I didn’t listen to my welding instructor so I didn’t learn to weld right. My project ended up not looking right and got a bad score on it. I went back to my welding instructor and learned to weld right so I could make my next project look better. It all started when I didn’t listen. First I didn’t hold my welding gun right so it wouldn’t allow me to make good welds. When
