Abstract

A microwave sensor for tip clearance measurement on aircraft engine is designed. The probe of the sensor is a patch antenna structure

it measures distance by comparing the phase of the receive signal with the transmit signal. It can avoid influence of fuel and pollution of engine

and has high measuring precision and stability. On the basis of theoretical analysis

model of microwave sensor which operates at 24 GHz is established

sensitivity is obtained by simulation more than 0. 5° / mm at measurement range of 0. 1

6mm and verify the correctness of the design.
