Aerospace market
• During the second half of the 20th century, hydraulically
driven systems replaced the original mechanical flight
controls.
• The main technological breakthrough came in 1984, when
Airbus introduced fly-by-wire controls on its A320 single-
aisle jetliner, with a computer controlling the actuators for
flight control. Boeing developed a similar approach starting
with its 777 widebody twinjet.
Design engineers began to think about enhancing this baseline
design around the year 2000, taking a much closer look at
electrical systems. The Airbus A380 super-jumbo jet, for
instance, eliminated one of the three traditional hydraulic
circuits, replacing it with an all-electric backup system for
flight controls.

The development of electrical systems increases the needs of new
actuators and sensors to bring performance and save:
Cost
Weight
with a high level of reliability
Fly-by-wire systems should integrate a lot of functions in a limited
package.
For new actuators generation, the need is to measure:
Absolute position
Temperature
Loads
Information for diagnosis or condition based
maintenance

Aerospace market
In parallel to the development of fly-by-wire systems, the aerospace operators
want to purchase Pay By Hour solutions. It requires a customized
maintenance per aircraft to reduce maintenance costs and increase the
aircraft availability => Condition Based Maintenance (CBM)
The introduction of CBM should also enable to increase flight security by a
better follow-up of the mechanical parts.
For instance helicopter “Oil and gas” market is demanding this PBH offer.

Condition Based Maintenance
For example, the target is not to manage OTL
(Operating Time limit) anymore for helicopters
transmission bearings but to continuously
know the actual condition of the bearings.
The challenge for NTN Corp is also to use the
measurements through the bearings to monitor
the surrounding mechanical parts.
The target would be to have a inflight system
that would enable to know the real conditions
of usage of the different systems to predict the
optimized maintenance period.

Maintenance : main challenge for Industry and Aerospace
CBM is based on physical measurements and parameters evolutions.
At the interface between moving and static parts of any machine, the bearing is naturally the
most direct place to collect data in order to survey systems.
NTN-SNR in continuously developing a range of technology bricks that will allow, in the
future, to know in real time the status and estimate remaining life of the most critical parts.
Condition Based Maintenance (CBM)

Mechatronic technology development for CBM
• Loads applied on the system
• Torque applied on a transmission or a driveline
• Precise speed and angular position information
• The deep and extensive knowledge of the bearing system to
simulate the impact of these loads.
• ….
NTN is permanently conducting research activities to develop the new technologies that will bring the requested information to the CBM control system :

Load measurement technologies
Wheel Bearing Load Sensor
Low strain
High strain
Contact forces
Contact forces are measured at several positions on the bearing. Fx, Fy, Fz, Mx, Mz can then be calculated thanks to a real-time algorithm, temperature independent and without power-on calibrating.

Vehicles
9 years ago, this collaboration with an OEM
was the first experience for NTN to check new
technologies for bearings failures detection.
Tests have been conducted on test bench as
well as on vehicle.
Very encouraging results pushed NTN to
continue its efforts whereas passenger cars
and light trucks markets were not confirmed.

Motivated by high owning costs, Railway
market also proved to be a very good
candidate.
A multi partners project led to :
- extensive lab characterization
- 4 years field experience in
commercial use.
Multi parameters analysis has been improved
to lead to the actual proprietary technology.
