Background

Over the years that DEEP has been part of the school’s curriculum, the Underwater Engineering course has been popular. The subject of projects came up in discussions with alumni, and many said that Underwater Engineering was the most fun of the DEEP project options. Naturally, Clay and I chose this project. Our main sources of inspiration came from the Boeing CH-47 Chinook helicopter, with a dual counter-rotating rotor design and the Boeing AV-8B Harrier II Plus jet, capable of vertical takeoffs and landings. My father asked why we used design features from aircraft to design a submersible craft, for use under water. I replied that we wanted a challenge. It turned out to be much more of a challenge than we had expected. The propellors and motors turned out to hinder our progress, and the propellors came right off as soon as we put the project underwater. Then, we gave into Mr. Harlan’s advice and used bilge pumps as our main source of propulsion. We hope that the chinook design will be improved in future years, as well as further development of the harrier design. In conclusion, there is no real background for our chinook design, which is why we initially chose it. The harrier design was chosen because it was a plane and a helicopter combined.
