ABSTRACT
Vortex refrigeration is a highly sophisticated system that contains a vortex tube which due to centrifugal force expels the internal energy of the air while the air at the centre core is made cooler. In this type of system the effectiveness is too low but considering its small size this can’t be ruled off. This is used as personal cooling system in suits that are designed to withstand heat.

Abstract:
superalloy, exhibits excellent mechanical strength and creep resistance at high temperatures, good surface stability, and corrosion and oxidation resistance. Also called high-performance alloy, Superalloys typically have a matrix with an austenitic face-centered cubic crystal structure. A superalloy's base alloying element is usually nickel, cobalt, or nickel-iron. such materials allow the turbine to operate more efficiently by withstanding higher temperatures and Superalloy development has relied heavily on both chemical and ....etc

WELDING
– Welding is a materials joining process which produces coalescence of materials by heating them to suitable temperatures with or without the application of pressure or by the application of pressure alone, and with or without the use of filler material.
– Welding is used for making permanent joints.
– It is used in the manufacture of automobile bodies, aircraft frames, railway wagons, machine frames, structural works, tanks, furniture, boilers, general repair work and ship building.

ABSTRACT:
Conventional closed die forging, is widely used for manufacture of superalloy parts. Despite recent technological advancements in the area of forging design, empirical and trial-and-error methods are still widely used in forging super alloy materials. This paper investigates the effect of flash thickness and various geometrical forging design parameters including internal and external drafts and internal and external corner radii, on the die cavity filling, forging load and raw material cost when forging Nimonic80-A a supera ....etc

DEVELOPMENT OF HIGH PRECISION SLOTTED ARRAY WAVE GUIDE ANTENNA FOR AEROSPACE APPLICATION
INTRODUCTION:
Missiles are guided towards the target through the seeker. Mono pulse antennas give the location of target. Thus tracking of the target depends upon the performance of the antennae.
The slotted wave guide array antenna offer various advantages like planar configuration and compact structure.
The performance of these antennae depends upon various parameters like slot ....etc
