Internal ballistics of a pneumatic potato cannon
Basic laws of thermodynamics and mechanics are used to analyse an air gun. Such devices are often employed in outdoor physics demonstrations to launch potatoes using compressed gas that is here assumed to expand reversibly and adiabatically. Reasonable agreement is found with reported muzzle speeds for such homebuilt cannons. The treatment is accessible to undergraduate students who have taken ...
متن کاملOne Dimensional Internal Ballistics Simulation of Solid Rocket Motor
An internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. In this model a 1-D unsteady Euler equation with source terms is considered. The flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. The governing equations in the combustion chamber are solved numerically by using the Steg...

متن کاملForensic Ballistics
Forensic ballistics is the application of ballistics for forensic purposes. The basis is formed by wound ballistics. Two main mechanisms of injury are differentiated: the crush-mechanism resulting in the permanent cavity and the stretch-mechanism resulting in the temporary cavity. The missile-tissue interactions such as yawing, deformation, fragmentation, and bone contact are explained here and...
متن کاملStudies on the Internal Ballistics of Composite Solid Rocket Propellants Incorporating Nano-Structured Catalysts
This paper deals with the analysis of burn rate using various catalysts of Iron Oxide and determining which gives the higher burn rate with low pressure variation. The Ammonium Perchlorate (AP) was obtained and ground into fine powder with the particle size ranging from 63 to 125 μm. The propellant strands were prepared with proportions by mixing AP with the binder (Hydroxyl Terminated Polybuta...
