Abstract: There are several firing tests of cannonballs. In sand firing tests, cannonballs without gunpowder charged are fired against sand pile. When a cannonball collides into sand, stress occurs on the cannonball due to the impact. In this study, stress analysis was done to find whether the cannonball is fractured, and safety factors were obtained. It was found that under the initial condition, the cannonball did not experience high stress enough to cause fracture.

Keywords: stress, sand, collision, behavior, safety factor, fracture

2. PRELIMINARY STUDY OF STANDING CABIN CONCEPT FOR DOMESTIC COMMERCIAL FLIGHTS IN MALAYSIA

Authors: FAIRUZ I. ROMLI , NORHAFIZAH DASUKI

Abstract: The market competition between airlines today has basically changed towards the affordability of air transportation service. The airlines are competing to lower their ticket prices as to capture high demands from both leisure and business travelers who are also price-sensitive customers. An idea of standing cabin, where the passengers are transported in a cabin of an aircraft in an upright position, has been proposed to reduce the operational flight costs and hence the charging price to the passengers. This paper explores the practicality of such idea with a case study that is focused on the domestic flights market in Malaysia. All in all, it can be concluded that the idea has a big potential to be applied by the current airlines servicing the market.

Keywords: vertical seat, standing cabin, aircraft cabin

3. ANALYSIS OF DRAG COEFFICIENT OF CANNONBALLS COLLIDING INTO WATER SURFACE

Authors: H. S. BANG , W. C. CHOI , H. S. LEE , S. H. PARK

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.

Authors: MUKUL ANAND , PRAGYAN KUMAR SARMA , S. SHARMA , T.Y. LADAKHI

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

Keywords: Turbojet Engine , Turbocharger, Turboprop Jet, Gas turbine
