Background 3

Sponsor Triumph specializes in the production of aerospace Company: Triumph Engine Control Systems components such as: Representative: Duane James ■ Fuel pumps ■ Fuel metering units Location: West Hartford, CT. ■ Fuel controls ■ Electronic engine control systems Budget: $1000 Advisor: Dr.Helena Silva 4

Background Challenge: Solution: Aircraft manufacturers strive to make aircraft as A distributed control sensor, or a “smart sensor” will light and strong as possible without increasing the condition and process its data locally near the cost drastically. sensor and provide a digital equivalent of a sinusoidal output. Distributed control sensing (DCS) is widely used in many consumer products but the aerospace To accomplish this we must design and connect a industry has been slow in implementing this conditioning and processing circuit to a Commercial technology. This design project provides a step Off The Shelf (COTS) sensor. towards implementing DCS technology. 5

Approaches 6

Approaches Possible Sensors Selection: Triumph recommended we improve the VR Sensor because it is most frequently used. ● LVDT (Linear Variable Differential Transformer) ● RVDT (Rotary Variable Differential Transformer) ● PMA (Permanent Magnet Alternator ● VRS (Variable Reluctance Sensor Passive) 7

Approaches VR Speed Sensor ● Frequency and voltage are directly proportional. Converting the Passive Sensor into an Active Sensor. Rectify voltage from the differential sine wave ● sensor output. Convert analog frequency to TTL logic signal. ● Use microcontroller unit (MCU) to transmit a ● serial output to engine control module (ECM) via controller area network (CAN). 8

Demo Day Plan 18

Demo Day Plan We will present a 3D printed example of our VRS “smart sensor” as well as a working prototype model connected to a lathe. Audience may use the lathe to test the “smart sensor” and reference its accuracy to our digital laser photo tachometer and oscilloscope by varying the speed between 780 to 3200 rpm. 19
