"Propulsion Through Ages "

Department of Mechanical Engineering and Institution of Engineers (India) Students' Chapter organised  a Technical talk on "Propulsion Through Ages " by    Sri Jasperlal, VSSC Trivandrum  on the 28th of March 2015.

The talk threw light on a lot of things starting from the basics of Propulsion, he further explained the term propulsion being derived from two Latin words:  pro meaning before or forwards and pellere meaning to drive.A variety of methods included under Propulsion were discussed like:

• Ground propulsion which includes any mechanism for propelling solid bodies along the ground, usually for the purposes of transportation.
• Marine propulsion - the mechanism or system used to generate thrust to move a ship or boat across water. 
• Spacecraft propulsion having any method used to accelerate spacecraft and artificial satellites. There are many different methods. Each method having its own drawbacks and advantages were graphically explained.

Interestingly he introduced the lesser mentioned about 

Human / Animal locomotion, which is the act of self- Propulsion by the animal/Human which includes running, swimming,jumping and flying, applying the Newton's third law of motion.

 The Sessions were interactive with active groups interrupting the speaker for clarifications.
