Özet

According to the conceptual similarities between nature and transportation, the design of systems and vehicles that are inspired by nature and attempt to solve a problem are currently ongoing research topics. The examination of living organisms with biomimicry methodology is essential to the physical and philosophical imitation of nature. Thus, the barriers between natural and engineering sciences are torn down, and the basis for academic and industry references is constructed.

Submarines are frequently employed for vital functions and utilize the energy stored in batteries, particularly when in a submerged state. At that time, the service range is defined by stored energy. The need for greater energy capacity to accommodate a longer range will result in an increased overall weight and, therefore, an increase in required propulsion power. Rather than engaging in such a dilemma, the available battery pack can be efficiently utilized by consuming less energy during the same operation. Enhancing the propulsion system or optimizing the body form to minimize resistance might enhance energy efficiency. The purpose is to determine a bio-inspired hull form exposed with less resistance than the DARPA SUBOFF. The body forms such predatory fishes as Barracuda, Dorado, Little Tunny, and Sailfish are compared to the bare SUBOFF.
