Design of S tructural I ntegrity and L eakage D etection S ystem (SILDS)

1. Tallahassee Innovations Sponsored by Lockheed Martin Design of Structural Integrity and Leakage Detection System (SILDS) Tobias Alexander Marcus Hoban Shaun Murphy Sam Zaila 3/29/2005

2. Design Scope/Objective Build a fluid sensor system that will detect and feed information indicating hydraulic flow loss due to damage done by “weapons effect” in a matter of seconds *** Simply put, this means that if a portion of a piping system is damaged in any way, that the fluid, in this case water, flowing in the system will be rerouted to still reach the other, undamaged portions of the system.

3. Previously, response to damage to ships have been inefficient and cumbersome Once ship was damaged, information relayed throughout the ship by radio To shut down portions of a system, manually operated valves were used Disadvantage: Slow Response Time History Photo Courtesy www.military.cz Photo Courtesy www.military.cz

4. Hydraulic System Rupture Detection System Open/Close Smart Valves PC w/ Data Acquisition System User Friendly Interface Design Solution

5. Hydraulic System 1inch piping 5 rooms with possible ruptures in each room Rupture Detection System Flow meters Strain rosettes Pressure transducers Emergency “Open” or “Close” Valve response system Solenoid Valves Control Valves Data Acquisition System LABView Initial Design Possibilities ***For each of the requirements given to us by our sponsors, we came up with a few possibilities for solutions; from there, we chose which would be used. Choices made by price, availability, compatibility, etc.

6. Hydraulic System 1inch piping 3 rooms with possible ruptures in each room Rupture Detection System Pressure transducers Emergency “Open” or “Close” Valve response system Solenoid Valves Data Acquisition System w/ user interface LABView Modified Design Possibilities *** Purpose of design requirements being modified was mainly to keep project under budget and also keep with some of the original requirements given by sponsor.

10. Purpose is for storage of fluid, in this case, water Should hold at least 5 gallons of water Accumulator (storage tank)

11. Grainger CV-4T Size used: 1 inch Purpose is to minimize, or eliminate, backflow Connected in-line with tubing $11.14 each Check Valves

12. Diameter used: 1 1/8 inch Approx. 30 ft. of piping used Tubing will be soldered for connections $30 per 20 ft. (price is subject to change) Copper Tubing

13. Size used: 1 inch Purpose is to simulate rupture(s) in our system Connected in-line with tubing $11.34 each Globe Valves

14. Water Ace S1300/R6S Purpose is to control fluid velocity and flow through system Power rated at 1/6 hp Maximum flow: 1500 gal/hr $64.00 Pump

15. Tubing cut to size Cleaned off pieces (sandpaper) Applied flux (used only on control valves) Applied Teflon tape to threaded pieces Attached threaded pieces Soldered together system Fabrication Process

16. Rupture Detection and Prevention System

17. Final Design (including rupture detection system) AC I/O Modules & Relay Module Control Valves Pressure Transducers DAQ Board & Labtop

18. Electrical Components: AC I/O Modules Control Valves DAQ Software and DAQ Board Pressure Transducers Relay Module Parts Selection

19. Relay Azeotech RB16 Interface a LabJack U12 with high voltages/currents Connects up to 16 I/O modules $89 I/O Module Digikey 70M-OAC Works as a switch for the control valves $9.13 each Relay & I/O Modules

20. White Rodgers #1303 Control Valve Covers most industrial laboratory applications 24 Vac coils Can be opened or closed manually or by powering the valve Max pressure differential of 15 psig Response time Approx. 45 sec $106.40 each Control Valves

21. Data Acquisition (DAQ) • Azeotech LabJack U12 • Easy to Use; Plug-and-Play USB Device • Many LabJacks can be interfaced to a single PC • Inexpensive, external solution for high channel count applications • Price: $119 • Data Acquisition Software • DAQFactory Express – Supplied by Azeotech as a cheap and easy solution

22. Pressure Transducers • Omega PX303-100G5V • General Purpose Pressure Sensors • 5V DC Output • Response Time: 1 msec • $255 each

23. Final Design

24. Calibration Procedure

25. Calibration Procedure(cont’d)

26. 5. Flow/ Valve Position 2. Pressure Indicator 6. 2-D Pressure Graphs 4. Emergency Start/Stop Button • Start/Stop Button 3. Valve Indicator DAQFactory User Interface

27. Bill of Materials

28. Use solenoid valves instead of control valves (including 3-ways valves when possible) More presentable and user friendly interface (possible with pro version of DAQFactory) Use of a larger pump for better flow and higher pressure Better placement of valves in mechanical system for lower loss of fluid (water),mainly check valves Possibly test other methods for detection of damage Possible Modifications
