Aircraft condition monitoring system (Advanced Flying Laboratory)

Can fiber optic technologies effectively monitor aircraft structures?

Using the FBG sensor technology, we developed a system for monitoring the aircraft condition, which made it possible to evaluate its structural health, even during its operation.

ABOUT THE CLIENT
  • universities and private companies
CLIENT EXPECTATIONS
  • development of a new monitoring system featuring increased mobility, robustness, small dimensions, and minimal power consumption
  • new FBG based sensors designed for embedding directly into the composite structures and joints
INITIAL STATE
  • many aircraft’s spaces and parameters are not being measured
  • the monitoring deflection of all controlled surfaces is missing
  • available monitoring systems too big or lacking the functionality
WHAT did the client turn to us with

The project’s goal was the development of an aircraft condition monitoring system enabling the assessment of the aircraft’s structural condition, especially after a harsh landing or flight through heavy turbulence. Another project’s challenge was the development of new FBG strain sensors for embedding directly into the composite structure and joints in order to monitor the entire process of aircraft construction, and its health during its operation.

Benefits of the solution compared to conventional methods

I. COMPLEX STRUCTURE HEALTH OVERVIEW

The system receives information from over 100 stress sensors built directly into the aircraft composite. Thus, it is possible to evaluate the state of the structure after a hard landing or passage through strong turbulences.

II. Functional multiparametrical measurement platform

The system was built into the U-15 and its functionality was verified by measuring up to 16 flight parameters in test flights.

III. Does not affect the rigidity and load-bearing capacity of the structure

Verified by manufacturing and destructive testing of samples with built-in optical sensors and samples without sensors and subsequent comparison of measured results.

How did we approach the solution?

We have developed the Advanced Flying Laboratory Phoenix Air U-15 AFL, based on an all-composite S-LSA motor glider, which had a number of parts equipped with FBG sensors for monitoring strain, deformation and temperature. Those measured 16 flight parameters (flight speed and altitude, engine speed, load multiples, control surface deflections, etc.) and provided the customer with valuable real time information on the actual state of the aircraft’s technical life. In addition, we have verified that the deployment of optical fiber sensors does not significantly affect static strength and durability of tested structures.

Why work with us?

Our company was invited to the project thanks to its rich experience of using fiber optic sensors in composite materials. Our specialty is the development of monitoring systems and fiber optic sensors to suit the client’s needs.

FBG technology is the most suitable solution where conventional procedures fail or are not viable because of routine operation.

Our systems monitor continuously and in real time, so you will receive error notifications immediately without unnecessary delays.

High durability and reliability are the characteristics of fiber optic technology.
