Pistonless pump



INTRODUCTION:

NASA have developed a Low cost rocket fuel pump which has
Comparable performance to turbopump at 80-90% lower cost. Perhaps
the most difficult barrier to entry in the liquid rocket business is the
turbo pump. A turbo pump design requires a large engineering effort
and is expensive to mfg. and test. Starting a turbo pump fed rocket
engine is a c ....etc

ABSTRACT:
Pistonless pump for rocket has been proved to be the most economical than piston pump or turbopump.
In pistonless pumps, piston is absent. It has very much less rotating parts than that of piston pumps or turbo pumps. So, it has less friction losses and there by it helps to improve the efficiency of the engine considerably.They can be easily installed in the rocket than turbopumps.Also,it reduces the weight of rocket.

WHAT IS PUMP
Pump is a device which converts mechanical energy into hydraulic energy.
Principle: A partial vacuum created when internal parts of pump receives mechanical energy .
Oil is forced into pump due to atmospheric pressure on oil and suction created by pumping element.
Oil is squeezed b/w pump elements which increases pressure of fluid and then is forced out of pump and the cycle continues.

Comparison and Contrast between the OSI and TCP/IP Model



Introduction



This presentation would discuss some comparison and contrast between the 2 main reference models which uses the concept of protocol layering.

Open System Interconnection Model (OSI)
Transport Control Protocol /Internet Protocol (TCP/IP)

The Session Layer

The Session layer permits two parties to hold ongoing communications called a session across a network.
