Aircraft Wheel and Brake Testing

If you’re interested in learning about how Data Acquisition Systems are used for Aircraft Wheel and Brake testing, then you must check out this application story written by Al Hoge at Dewesoft.


Firstly, Parker Hannifin’s Wheel and Brake Division (AWB) located just outside Cleveland Ohio conduct a variety of tests to ensure the proper and safe operation of aircraft wheels and brakes.

They were using a range of different ageing instruments and systems to perform the tests.  Engineers were looking for a single system to perform these tests.  Dewesoft provided a system to fit their needs.


The division used a collection of test and measurement instruments to perform the necessary tests.  However, none of the instruments were synchronised.  Therefore, each was operated individually with a series of steps. Making it time consuming, with plenty of manual labour.  In addition, several technicians were involved with configurations being different test to test.  In addition, data was logged by hand on paper due to the lack of an integrated collection system. However, it got the job done with good results.  It just wasn’t as efficient as it could be.

They needed an integrated DAQ system with flexibility.  They recognised transition to new key technology would be a learning curve.  Therefore, they would need excellent after sales support.

Tests Undertaken by their old systems.

Firstly, take-off and landing are two of the most critical times in the operation of any aircraft.  The Parker Hannifin division was responsible for testing the main wheels, nose wheels, brakes, and related hydraulic components.  In addition, traceable, repeatable testing is critical for the certification process for new aircraft designs and ongoing safety and maintenance of aircraft fleets.

Secondly, the testing follows the regulations set by FAA, DO-160 and MIL Specs and European Aviation Safety Agency.  In the article, Al discusses in detail how the tests were conducted using their old systems. Such as dyno testing, combined load testing, endurance testing, roll testing and Proof and Burst Testing.

Challenge for the Aircraft Wheel and Brake Testing Division

Adjusting their way of doing the job and learning new technology.  As they would no longer require a mix of instruments or paper logs.

Why they chose Dewesoft

  • The DAQ Solution could provide require sample rate and vertical axis resolution.
  • DewesoftX Software comes with hardware with no extra costs or fees
  • DewesoftX has a built-in sequencer allowing the Division to automate their tests
  • Everything could be integrated and automated in one package

 Dewesoft Solution

In the article, there is detailed information on the hardware configuration.  In summary, the solution consisted of the following components:

  • SIRIUS Module with
  • 4 x Multifunction inputs
  • 4 x Low Voltage Inputs
  • DSI Adaptor to connect IEPE and charge accelerometers, microphones etc.
  • Several Multi Channel KRYPTON Modules for measuring temperature and additional voltage channels
  • KRYPTON TH Module thermocouple inputs
  • KRYPTON Voltage Inputs

Finally, the software’s flexibility offers immense value.  DewesoftX is a complete standalone DAQ Software package.  It requires no programming.  However, the built in sequencer allows users to adapt the software to specific test scenarios.  Any changes can be done easily without the requirement to create something entirely new.


The AWB Division are thrilled with their new testing system.  This is because Dewesoft’s Systems are modular and flexible.  Technicians can adapt the approach for different testing combinations.  Plus, the set-up time is reduced and there are more consistent results. Another advantage is Dewesoft hardware is expandable.  Therefore, additional modules of SIRIUS or KRYPTON can be added in the future if needed.
