AeroAcoustics

AeroAcoustics

MDS is a world leader in aerodynamics, acoustics, and infrasound. Its core staff include aerodynamicists and acousticians with a collective 60 years of experience in this specialized discipline.

Ongoing research and development topics include:

  • Developing infrasound and noise pollution mitigation technologies
  • Scale model testing to anchor theoretical results
  • Energy recovery
  • Flow conditioning and stability – Computational fluid dynamics (CFD)
  • Test Cell construction techniques with regards to sound transmission, sound absorption, and silencing

Our research in these key areas has resulted in improved test cell performance and cost savings for our clients, while extending the life of our test cells.

Infrasound and Noise Pollution Reduction

Our research into the destructive and potentially dangerous low-frequency pulsations known as infrasound spans almost two decades.

Our comprehensive design guidelines, developed through extensive scale model research and full scale validation tests, ensure smooth operation, high repeatability, and safe engine operation. Further, the structural integrity of the test cells and surrounding buildings are safeguarded through our design practices.

Scale Models

We use physical models to simulate complex geometries and configurations to enhance design solutions. We use these scale models to anchor our theoretical results to improve our understanding of aerodynamics and acoustics.

Energy Recovery

We are currently developing an advanced proprietary technology that will provide aerodynamic, acoustic, and economic benefits that will forever change the face of the turbine testing industry.

Thrust Measurement

Thrust Measurement

Areas of Development

  • In-Frame Calibration System
  • Multi-Axis Thrust Frame includes a complete force measuring module along with associated calibration equipment required to calibrate and measure the six components of thrust. Our Multi-Axis Thrust Frame provides the raw data as well as the calculated vector magnitude, angle, and location to the data acquisition system.
  • We have developed Industrial and Marine Engine Load Absorption Systems to simulate the most complex load simulation applications. Among them:
  • Constant Speed (Power Generation)
  • Variable Speed (Marine and Mechanical Drive)
  • Constant Torque (Pumping)
  • Load Profile Matching
  • Load Cell Thermal Regulation and Characterization provides improvements in thrust and thrust calibration accuracy using temperature stabilization to minimize error related to ambient temperature fluctuation.
  • Centerline Pull Development of servo hydraulic systems for the comparison of engine centreline force to the force measured by the Thrust Measurement System working load cells, for the purpose of characterizing and mitigating the errors related to the load offset.
  • 155,000+ lbf Thrust Capacity Continuous Improvement on measured thrust accuracy through working with our load cell vendors to minimize errors, and by reducing the non-repeatable errors associated with the transfer of engine services and instrumentation across the Thrust Measurement System.

Pushing the Limit

MDS designs evolve from careful consideration of operational principles that minimize non-systematic errors for the greatest measurement accuracy in the industry.

Design for Maintainability

Our Thrust Measurement Systems are not only designed for our clients’ needs today, but they are also built to meet our clients’ future requirements. At MDS, our focus is to consistently remain accurate, versatile, flexible, and cost effective without compromising quality.
