Moment Weighing Scales for Jet-Engine Blades Series WM - Schenck Nederland

  • Precision measurement of jet-engine blade moments
  • Simple balancing of bladed rotors
  • Single-axis type for narrow blades and bi-axial type for wide chord fan blades
  • Optional software for optimized blade distribution

Design

Electronic scale on a base plate with built-in levelling device.

Weigh-beam mounted on knifeedges for friction-free operation, including oil damping, measuring system with load-cell and microprocessor-controlled measuring unit (digital display), thus, ensuring high weighing accuracy and repeatability. An adapter flange is provided for mounting the blade adapter.

Single-axis or dual-axis types according to the application and blade form.

Range of application

Determining the radial, axial and tangential moments of jet-engine blades for evaluation of mass and position of center of gravity.

Application of the scale in testing, inspection and quality control.

With the use of the optional BLADIS Net blade-distribution system, the exact position of the blade in the assembly can be determined.
