Case Introduction

Application:Aero Space

Gas turbine engine - multi-channel measurements for vibration, temperature and pressure.

Even within limited budgets, aerospace engine designers must always seek technical innovation in the areas of safety, reduced noise, weight and overall efficiency.
As a result, their goal is to design new engines that are safer, quieter, lighter and more efficient.
Performing the tests on these engines is extremely expensive so a reliable data recorder is required.
Data loss during a test has serious financial implications and can negatively impact further project developments.
The WX-9000 can be used as a dependable data back-up recording solution for PC front-end measurement systems. The WX feature set provides reliable data recording with protection from catastrophic data loss.

  • Channels: 20 to 32ch
  • Frequency bands: 40k to 60k Hz
  • Recording times: 50 seconds to 20 minutes

The ability for rockets to leave the earth's atmosphere and reach outer space is based on the technology involved in rocket engine design. The rocket engine design considerations (that were incorporated during the development of the LE-5) included not only the ability to guarantee that it would successfully reach outer space reliably but reusability which would make the use of these rockets economically feasible. TEAC Data Recorders have been employed as test equipment since these engines were developed some 30 years ago.

Engine Vibration Analysis is very important data used to continue improved designs of rocket engines. This data is used to increase the reliability and durability of these devices. The tests have to be performed using real world conditions these engines will experience such as extremely low temperatures, drastic pressure levels and high speed rotation. If for example, the vibration level is over a prescribed threshold, this can decrease engine efficiency and also have a negative effect on other rocket components. TEAC Data Recorders are used for their ability to accurately record this measurement data in real time.

A big advantage that TEAC Data Recorders have over many other recording systems is their ability to capture wideband data on multiple channels. Considering the expense involved in performing even a single test, the recorder's capacity to capture this data across multiple channels is an important cost saving benefit.

About Japan Aerospace Exploration Agency (JAXA)

On October 1, 2003, the Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL) and the National Space Development Agency of Japan (NASDA) were merged into one independent administrative institution to be able to perform all their activities in the aerospace field as one organization. This will range from basic research and development to utilization. Under our corporate message "Reaching for the skies, exploring space," JAXA is pursuing great possibilities in many aerospace fields. We are striving to succeed with various research and development missions in order to contribute to the peace and happiness of mankind.

Application:Railway

Railways are attracting attention as environmentally-friendly transportation systems and are becoming recognized as a more convenient mode of travel in recent years. In order to maintain safety and reliability, it is required that vehicle architecture and general train operations are periodically reviewed so that improvements can be made. TEAC's WX-9000 plays a key role in the evolution of this outstanding technology with its ability to measure and record the physical phenomenon involved with rapidly moving vehicles.
The WX-9000 is used in the development various railway technologies due to its wideband, multi-channel and long duration recording capabilities.

Advancements in vehicle body design

Measurement and analysis of pressure, strain and vibration on a vehicle body when moving along with the WX-9000's ability to record the railway ATC (Automatic Train Control) signals will support further safety and reliability advancements.

To support ride quality improvements

The WX-9000 is extremely helpful with future improvements to ride quality by analyzing internal noise and moving vehicle vibrations.

Concern for the environment

WX-9000 helps to reduce the environmental impact of these vehicles by recording and analyzing a tunnel's air-pressure wave (noise generated due to a rapid air pressure change) along with external vehicle noises.
