Microturbines

Microturbines operate on the same thermodynamic cycle, known as the Brayton cycle, as larger gas turbines. In this cycle, atmospheric air is compressed, heated, and then expanded, with the excess power produced by the expander (also called the turbine) over that consumed by the compressor used for power generation. The power produced by an expansion turbine and consumed by a compressor is proportional to the absolute temperature of the gas passing through those devices.....................>>>>Read More

Next Generation Engines

Gasoline direct injection (GDI) engine technology has received considerable attention over the last few years as a way to significantly improve fuel efficiency without making a major shift away from conventional internal combustion technology. In many respects, GDI technology represents a further step in the natural evolution of gasoline engine fueling systems. Each step of this evolution, from mechanically based carburation, to throttle body fuel injection, through multi-point and finally sequential multi-point fuel injection...>>>Read More

HEMI engines

The HEMI engine is a four stroke, spark ignition, reciprocating type, internal combustion engine.The design of the combustion chamber for a spark ignition engine has an important influence on the engine performance and its knocking characteristics. The design involves the shape of the combustion chamber, the location of the spark plug, and the location of the inlet and exhaust valves. The important requirements of a spark ignition engine combustion chamber are to provide higher power output with minimum octane requirement, high thermal efficiency and smooth engine operation......>>>>Read More

Just In Time Manufacturing

JIT is a management philosophy that strives to eliminate sources of manufacturing waste by producing the right part in the right place at the right time. The Waste results from any activity that adds cost without adding value, such as moving and storing. The idea of producing the necessary units in the necessary quantities at the necessary time is described by the short term Just-in-time.The implementation of this management philosophy in industries like the automobile industry can bring about a see saw change in both quality & quantity since in a JIT system, underutilized (excess) capacity is used instead of buffer inventories to hedge against problems that may arise.........>>>>Read More

Military Radars

RADAR (Radio Detection and Ranging) is basically a means of gathering information about distant objects by transmitting electromagnetic waves at them and analyzing the echoes. Radar has been employed on the ground, in air, on the sea and in space. Radar finds a number of applications such as in airport traffic control, military purposes, coastal navigation, meteorology and mapping etc. RADAR (Radio Detection and Ranging) is basically a means of gathering information about distant objects by transmitting electromagnetic waves at them and analyzing the echoes. Radar has been employed on the ground, in air, on the sea and in space. ......... >>>>Read More

Stealth Fighter

Stealth means 'low observable'. The very basic idea of Stealth Technology in the military is to 'blend' in with the background. The quest for a stealthy plane actually began more than 50 years ago during World War II when RADAR was first used as an early warning system against fleets of bombers. As a result of that quest, the Stealth Technology evolved. Stealth Technology is used in the construction of mobile military systems such as aircrafts and ships to significantly reduce their detection by enemy, primarily by an enemy RADAR.......... >>>>Read More
