Troy was a submarine designed by oceanographer Fabien Cousteau and engineer Eddie Paul to look like a great white shark. ==Submarine== Troy was a , submarine designed to look like a great white shark. It was created by oceanographer Fabien Cousteau and engineer Eddie Paul's E.P. Industries so that Cousteau could observe and film sharks in their natural habitat without chumming the water.〔 The submarine had space for one person, Cousteau, who piloted the vehicle while lying on his stomach, propped up on his elbows. A wet sub, Troy was filled with water while operating. To breathe, Cousteau carried full diving gear weighing about , providing about 6.5 hours of air.〔 To prevent air bubbles leaving the vessel, spent air was redirected into two empty tanks.〔 Cousteau entered Troy by flipping open the "head" and crawling in backwards. Troy was covered in SkinFlex fabric combined with glass and sand to make it look and feel like shark skin.〔 The "skin" was sewn together on the top and held together with Velcro on the bottom.〔 Under that was a layer of bullet-proof Lexan and steel "ribs" to allow the submarine to survive a shark attack.〔〔 The spine was made out of flexible plastic. Scars and epoxy teeth were added for realism.〔〔 Troy was designed to move in a shark-like manner using a series of joysticks to control speed, direction, and pitch.〔 The eyes could roll, the gills puffed, and the mouth opened and closed to enable shark-like communication. Its tail functioned as a rudder and was powered by compressed air.〔〔 A propulsion system designed by the United States Navy kept noise to a minimum.〔 The submarine could move forward at up to 5 knots, but was unable to react quickly.〔〔 Depth was controlled by three inflatable buoyancy bags. Unlike real sharks, Troy was odorless.〔 Troy had three cameras to film its surroundings.〔 Originally, cameras were positioned in the shark's eyes but the resulting images were too "disconcerting to try to make sense of" in real time, so the camera was moved to the top of the shark's head, disguised as a fish.〔 An infrared camera was hidden in a suckerfish attached to the shark's body. The pilot had a video monitor showing him what was going on outside the shark.〔 Originally Troy had a $100,000 budget and two-month time frame.〔 After a year of trial and error in Paul's workshop and pool, the submarine was finally ready for open water testing.〔 Due, in part, to simultaneous documentary filming, overtime payments accumulated and the vessel ended up costing $200,000. It was originally named Sushi. Normally, sharks' behavior is affected by the attempts to observe them, with chumming and shark cages leading to footage of aggressive, open mouthed sharks that does not represent their natural behavior. Troy thus allowed Cousteau to observe the animal in more natural way. "You must 'become' one of them ... to witness what sharks do amongst themselves naturally", Cousteau remarked. "By better understanding them we can take one more step towards eliminating the demon image we have created in our minds."〔 After some initial apprehension, sharks appeared to view Troy as another shark.〔 They stayed about away from it, the length of an adult shark, and rolled their eyes, puffed their gills, and changed directions in response to it. These behaviors were observed only in the presence of the shark, not with free divers.〔 Based on the behavior, Cousteau said it appeared Troy was accepted as a dominant female by other great white sharks, but added that he was hesitant to say the behavior proved the sharks saw the submarine as a shark.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Troy was a submarine designed by oceanographer Fabien Cousteau and engineer Eddie Paul to look like a great white shark.==Submarine==Troy was a , submarine designed to look like a great white shark.
