  1. Wireless Test Instrumentation System for Rotating Parts ECE Team 167 Lawrence Bogan Jeremy Neaton Adam Bienkowski Michael Golob ME Team 29 Sean Handahl Ken Thompson Caleb Browning Paul Inguanti - Company Advisor Chris Winslow - Senior Test Engineer Rajeev Bansal - ECE Project Advisor Robert Gao - ME Project Advisor

  2. Wireless Test Instrumentation System for Rotating Parts Outline • Company Background • The Problem • Project Goals • Wireless Transmission • Sensors • Microcontroller • Battery • Energy Harvesting • Timeline • Budget ME Team 29 - ECE Team 167 Senior Design Fall 2012

  3. Wireless Test Instrumentation System for Rotating Parts Sikorsky • Aircraft and helicopters • Founded 1925 by Igor Sikorsky • 1942 R-4/Hoverfly - first stable, single-rotor, fully controllable helicopter to enter mass production, most based off this design • Presidential transporters since 1957 - VH-3 and VH-60 • Well known products - UH-60 Blackhawk and SH-60 Seahawk • 75% sales military • 29% military global market share ME Team 29 - ECE Team 167 Senior Design Fall 2012

  4. Wireless Test Instrumentation System for Rotating Parts Problem • Wired Sensors have some deficiencies that reduce the reliability of the system • Wires can be heavy • Wires break, connectors fail • Wireless Sensor Networks (WSN) solve these problems, but bring new problems to the table: • System maintenance must be minimal • Must last for a minimum of 1 year, 3 years recommended • Power Consumption for the system must be very low • Battery Life and Energy Harvesting are key focal points • WSN must operate in a noisy environment • Proof of concept that the receiving data is the same as the transmitted data • Packaging/Installment Issues • Entire system must fit in a 1.5" diameter by 5.1" long electronics cavity • Packaging must protect the WSN from high vibrations, temperatures, and condensation ME Team 29 - ECE Team 167 Senior Design Fall 2012

  7. Wireless Test Instrumentation System for Rotating Parts Project Goals • ECE • Sensor selection / measuring of data • Signal analysis, storage, and transmission • Battery selection and power management • ME • Design and creation of test rig • Energy harvesting/energy generation to power/recharge system • Mounting and installation of sensors and transmitter ME Team 29 - ECE Team 167 Senior Design Fall 2012

  8. Wireless Test Instrumentation System for Rotating Parts Block Diagram ME Team 29 - ECE Team 167 Senior Design Fall 2012

  9. Wireless Test Instrumentation System for Rotating Parts Wireless Transmission • Wireless device must be able to transmit data over a distance of about 40 feet. The measuring system is located in the tail rotor and the stationary receiver is located in the cabin. • Infrared Wireless - Very weak distance travel and must have a direct line of sight • Bluetooth - Covers up to 30 feet. It it designed for low-power simple wireless networking and supports fewer devices as well. Data can be transmitted relatively slow at times. • Wi-fi - Consumes a lot of power and can produce too much heat. Very expensive as well. • ZigBee - Wireless chip that is low cost and provides low power consumption and transmits data at a far distance. ME Team 29 - ECE Team 167 Senior Design Fall 2012

  10. Wireless Test Instrumentation System for Rotating Parts Sensors • Temperature • -20 to 250ºF • Vibration • Accelerometer • Piezoelectric • ~20kHz vibration frequency ME Team 29 - ECE Team 167 Senior Design Fall 2012

  11. Wireless Test Instrumentation System for Rotating Parts Microcontroller • Acquire sensor data • Perform Fast Fourier Transform • Data compression and storage • Control of wireless tranceiver • Standby mode when helicopter is not running ME Team 29 - ECE Team 167 Senior Design Fall 2012

  12. Wireless Test Instrumentation System for Rotating Parts Battery • Battery needs to last at least 1 year, Sikorsky would like it to last 3 years • Needs to be able to work after 30 days of inactivity • Looking into high capacity batteries that are able to fit into the cavity • Possible batteries of interest are lithium iodide and lithium ion ME Team 29 - ECE Team 167 Senior Design Fall 2012

  13. Wireless Test Instrumentation System for Rotating Parts Energy Harvesting • the process of gathering extra energy to be used for power. will extend the life of the electronics • can use thermal, vibration, or magnetic energy harvesting methods • thermal relies on a temperature gradient. unpredictable in a helicopter due to altitude changes. • vibration is viable and relatively constant in helicopter. turns strain into energy. energy created is relatively small. system may be too large to implement • magnetic uses coils and a magnet to create a kind of alternator. every time the coils pass the magnet energy is generated. efficient but will needs installation on the moving parts ME Team 29 - ECE Team 167 Senior Design Fall 2012

  14. Wireless Test Instrumentation System for Rotating Parts Timeline ME Team 29 - ECE Team 167 Senior Design Fall 2012

  15. Wireless Test Instrumentation System for Rotating Parts Budget • Our budget, from Sikorsky is $4,000 and will cover the following: • Wireless Transmitter • Microcontroller • Sensors • Battery • Equipment for Energy Harvesting • Packaging for WSN • Representative Rotating System ME Team 29 - ECE Team 167 Senior Design Fall 2012
