12-Channel Rotary Telemetry System for
Aircraft Turbine
Duration
2
years
Team Size 8
Description
This Project is Data Acquisition and control of Telemetry System for High
speed aircraft Rotors which is essential in Design of Rotor blades to calculate
strength of material. Base band system has SPI-Master and Slave
architecture. This converts Strain and Temperature (Thermocouple,
XTR108) analog signals to Digital form using 12-bit ADC. Initially gains are
programmed using PGA’s, Bridge balancing done through programming
through DAC’s. To balance the bridge control Data are sent from ground
System to Base band as PWM protocol mixed signal has 120volts and control
data. This data is received and decoded by SPI Master and sent to
corresponding channels of slaves. Data acquisition is done in reverse way,
Turbine Rotor’s Data from Microcontroller (Cygnal C8051F12X) send to FPGA
(A54SX32A) through SPI which will convert the data into Bi-Phase and NRZ
format to the RF system. While in Rotation system works as MSPI Multi-Master
Mode, analog strain and temperature are collected and fed to ADC’s then to
microcontrollers and then to FPGA.FPGA converts data to Bi-phase format for
RF section to transmit the collected data. The whole assembly (Power, Base
band, RF) kept inside a rotor which as to rotate at high speed. Power to
rotary system is supplied via a Rotary transformer with an air gap of 1mm.
