Analysis of The Impact of Different Angles of Thrusters in Underwater Vehicles on Thrust Force in CAD Environment

Abstract

The need for unmanned underwater vehicles is increasing in the world and in our country. The use of unmanned underwater vehicles in ocean exploration, search and rescue, military and industrial applications is expanding day by day. In particular, unmanned underwater vehicles are an attractive option for underwater search, research and survey operations, as they are low cost compared to manned vehicles. In this article, a detailed vehicle design has been created and analyzed using the computer-aided design tool SOLIDWORKS. With these analyses, the effects of the angle of the engines positioned in unmanned underwater vehicles on speed, time, thrust force and precise positioning parameters will be explained by 2 simulation studies. The first of the simulations is the explanation of the data obtained as a result of the 45 degree angles of the thrusters to the body, and in the second simulation, the data obtained as a result of the positioning of the thrusters at 90 degree angles to the body. It has been observed that the angle of the thrusters positioned in line with the models made directly affects the maneuverability and thrust force. It has been observed that a vehicle positioned at an angle of 90 ° should be preferred in applications requiring gain from speed and time, and a vehicle positioned at an angle of 45 ° should be preferred in applications requiring precise positioning. In conclusion, in this study, it is defined how the thrusters positioning should be in order for the underwater vehicle designed to meet the requirements of a user to be the most efficient and suitable vehicle for the desired environment of mobility.
