Abstract: When a cannonball collides onto water, it can ricochet several times when a normal force generated larger is than sum of the weight and inertia force. The impact occurring during collision is influenced by the drag coefficient, lift coefficient, sea wave angle, cannonball speed, initial launch angle, etc. In order to determine the moving path of the cannonball, an analysis is done to calculate the position and velocity of the cannonball and the force acting on the cannonball using a finite element method. In this study, the drag and lift coefficients are calculated through experiment and energy equations. It is found that a high entry angle when collide into water surface results the high drag and lift coefficients, and that the ricocheting distance varies depending on the sea wave angle, launch angle and launch height.

Abstract: In this research paper an attempt has been made to design and analyze a small turbojet engine using scrap automobile parts, turbocharger being the major component. The engine has been designed and analyzed in Sikkim Manipal Institute of Technology using used turbochargers that can be used in modern automobile. In this design the thrust generated from the turbine section of a turbo charger is used to drive the power turbine generating the shaft power and also an attempt has been made to convert the turbo jet into turbo prop jet so as to increase its efficiency
