This document presents the design of an underwater bionic submersible called the "Iron Dolphin". It aims to allow for safe, personalized underwater exploration at decent speeds while being friendly to marine life. Modeling and FEA analysis was conducted on key components like the dorsal fin, universal joint, and cabin. The analysis showed the design meets structural requirements but fluid dynamics analysis indicates the cabin nose shape needs modifying to improve fluid flow. Future work includes further optimization and testing.

The coupling that can occur between a structure and fluid, known as aeroelasticity, can result in complex, even bizarre behavior. This is especially true when composite materials are used, as they can result in their own structurally coupled behaviors. This webinar will cover the basics involved in carrying out simple static aeroelastic as well as flutter analysis. In addition, we will also briefly explore the benefits of aeroelastic tailoring.
The Team H2politO: vehicles for low consumption competitions using HyperWorks Altair
The Team H2politO is a group of students of the Politecnico di Torino. The student’s background and profiles are very diverse, everyone comes from a different discipline of engineering and together they compose a complete Team. The disciplines range from Automotive and Mechanical to Electronics, Aerospace, Energy, Mathematics, Computer Science, Mechatronics, Management, Cinema and Media and Industrial Design. The Team mission is to shape a new generation of engineers, leaders in their fields, who represent the educational excellence in regard of each of their competencies.
The results of Team passion and hard work are three low-energy consumption vehicles completely designed and made by the Team: IDRA - hydrogen powered prototype; XAM – bioethanol powered parallel hybrid urban concept; XAM 2.0 –EREV city vehicle.
The main goal is to take part and win in Shell Eco-marathon, a competition that every year involves more than one hundreds of students teams arriving from all over Europe. Especially we would like to spread the Shell Eco-marathon values through ours, combining the sustainable development with a vehicle that uses the least possible amount of energy.
H2politO is a different, innovative and somehow unique project, is not just a Team but something more: it is a new type of conceiving educational, professional and personal growth. Team members aim at being perceived as an experimental laboratory where competences, capabilities and potentialities of future’s engineers are fostered. Students strive to become not only solid and advanced technical experts but, equally important, down-to-earth managers having excellent communication, leadership and teamwork skills.
Practical and hands-on experiences are doubtlessly a complementary and enriching form of educational path where it is very important the use of simulation software like HyperWorks. Team members have a real opportunity to lead their educational path by building and crafting their own thesis. Final papers are indeed part of a cluster of thesis which combines all the technological and organizational areas of development H2politO has envisioned and embraced.
The Team believes in hard work as the basis of future success. Students crave for continuously improving and strive for exceeding expectations by nurturing the team spirit in order to create those synergies able to add value to individual performances and capabilities. As a consequence, passion and team-spirit are really the foundation of H2politO values.

2. INTRODUCTION
• Recreational undersea exploration
• Current options:
Be a diver
Ride a sightseeing submarine
• Drawbacks of the current options
Diving: direct exposure to
dangerous marine lifes, need
certain training
Sightseeing submarine: Slow
speed, designated routes, not
welcomed by fishes
