This project aims to design and develop hydro jet which is integrated to Electric motor, whichis limited to run at 70% PWM. Which limits the efficiency of the system, to make an efficientsystem, hydro jet parameters are not defined which are desired to be defined by design fourimpellors for basic Radinn G2x Jet Pack design. The impellors will be four expected points inHydro Jet and final impellor is assumed to lie between these design points, to find the finalspecifications of the hydro jet, the hydro jet will be designed, using computational fluiddynamics they will be analysed. After analysis, they will be manufactured and tested in poolfacility where MGM controller will be used to measure the numerical data from electric circuitwhich powers the system to analyse the performance parameters to finalize the validity of 100% PWM. Microsoft Excel is used to calculate the Hydro Jet Geometric parameters, which areused in Solid Works, where parametric modelling is used to design impellors based ongeometric parameters calculated in Excel. Using Computational fluid dynamics hydro jetperformance is simulated and analysed. To validate the design further, prototypes aremanufactured and tested using workshop pool testing facility using MGM software. As a result,four hydro jet points are calculated, analysed and tested, four pumps are designed for specificflow rate, velocity and torque is calculated for four hydro jets. They are calculated and verifiedusing computational fluid dynamics, as a result flow rate, velocity and torques are calculatedfor all four hydro jets. Four impellors are manufactured and then tested in Radinn work shopand as a result current, power and rpm of the hydro jets are measured using MGM software.From power, rpm and current the torque can be calculated, while rpm is compared againstpredicted computational fluid dynamics results. The results from this project is limited toRadinn G2x jet pack, motor and other parts of the hydro jet’s Jet pack are standard parts
