Abstract: This paper presents the modelling of a novel autonomous Triple Mode Vehicle. The presented design satisfies the dimensional and material constraints for a vehicle which can maneuver on land, water and underwater. This autonomous vehicle can be used for surveillance with the help of RADAR and its location can be tracked using Global Positioning System. Using RADAR we present the resulting amplitude variation withthe distance of object from the source.

Abstract: A hydraulic check valve is a device that is installed to keep fluid from flowing backwards through the valves. Hydraulic check valves do not require any external activation; instead contain a mechanism that moves according to the flow of fluid through the valves. Hydraulic check valves are zero leakage devices, which can be used in locking hydraulic systems. When the fluid flows forward towards the valve, the mechanism allows it flow, whereas when the fluid stops flowing the mechanism plugs up the valve opening so that the fluid cannot flow backwards This project work is addressed to analyze the check valve under static and thermal load conditions. The pressure of 48.26Mpa has showed the check valve design is safe by obtaining factor of safety 3.15 under static load conditions respectively. Preheating the component from room temperature 250C to 400C at temperature of 71.10C and pressure 48.26Mpa has showed the check valve design is safe by obtaining factor of safety 3.022 under thermal
