Presentation Overview

• Background Information
• Project Scope
• First Semester (Design)
• Second Semester (Manufacturing)
• Test maneuvers
• Problems Encountered
• Possible Improvements

3
Project Background

• CAPS is researching the development of fully
  electric ships
• Developing real time hardware-in-the-loop
  simulation capabilities for electric ship power
  systems
• Navy hopes to be able to create fully electric
  ships

4
Project Scope

• Build a display for classroom and tour
  demonstrations
• Given budget of 3000
• Will monitor current and voltage changes during
  dynamic maneuvers

5
First Semester

• Needs Assessment
• Engineering Specifications
• Concept Generation
• -Initial Design
• - Final Design
• Cost Analysis

6
Needs Assessment
7
Engineering Specifications
8
Initial Design

• Not maneuverable
• Required too large of a pump
• Costly

9
Final Design

• More cost efficient
• Lighter and more maneuverable

10
Cost Analysis

• Projected materials costs were approximately
  2300.
• Though within the budget, still close to limit.

11
Second Semester

• Construction of Apparatus
• Project Components
• Final Product

12
Construction of Apparatus

• Took approximately two months to build
• Met with many delays

13
Project Components

• Tank
• Wooden Support
• Pump
• Motor
• Piping System
• Motor and Drive System

14
Tank

• 8x12x30 Acrylic tank
• ¼ in wall thickness
• Bound using Acrylic solvent

15
Wooden Support

• Constructed using 2x4 wood pieces and 2 ½ wood
  screws

16
Pump

• Teel 4RJ94
• 11/2 HP
• Used for Pools and Spas
• Requires 120 volt (typical wall plug)
• Pumps 160 GPM
• 8 to 4 Coupler

17
Piping System

• PVC Schedule 40 pipe and fixtures
• 4 to 2 Coupler
• Valves are orientated strategically to throttle
  water

18
Motor and Drive System

• Uses a 12 V DC motor
• Drives a 4 metal propeller
• Propeller weighs approx. ½ lb
• Supported by wood and aluminum

19
Final Product

• Eureka!!!!

Test Maneuvers

• There are five maneuvers for the apparatus
• Accelerating Ship
• Cruising Ship
• Coasting Ship
• Ship at Rough Seas

22

• Accelerating Ship
• Simulates the ship at start up
• Cruising Ship
• Similar to the accelerating ship maneuver, but
  adds use of the pump to simulate the ship already
  in motion
• Coasting Ship
• Simulates a ship moving in open water without use
  propulsion
• Currently cannot test

23
Ship at Rough Seas

• Two phases
• With aid of the pump
• Without aid of the pump
• Simulates a boat in rough seas where the
  propeller will enter and exit the water

24
Crash-Astern

• Simulates the effects of going into full reverse
  while already traveling at full ahead
• Currently cannot test

27
Problems Encountered

• Initially did not know everything to order
  through CAPS
• Wavered on what kind of pump to use
• Many unexpected delays in the ordering pipeline

28
Possible Improvements

• Connect system to LABView
• Change to the drive motor
• Add an automated mechanical lifting system
• Add a flow meter
• Change ball valves
