Turbo propeller test, turboshaft engine test




The design of high speed dynamometer for turbo propeller test, turboshaft engine test is based on the careful calculation and optimization of the conventional hydraulic dynamometer or eddy current dynamometer with our test bench application experience. The lightweight rotor brings lower weight and moment of inertia. High speed dynamometer can have turbo propeller test, turboshaft engine test, test of aircraft turboprop engine, gas turbine and high speed gearbox.

Dynamometer features for turbo propeller test, turboshaft engine test

 

  • Under the requirement of dynamometer rated power, the use of dual-rotor special structure can substantially reduce the rotor radius and weight of high speed dynamometer. The inertia can be reduced for more than 50%. The rotor outer edge linear speed is also significantly reduced to ensure the dynamometer high speed operation. The dual-rotor structure can reduce the overall weight and volume of high speed dynamometer.

 

  • The internal structure of high speed hydraulic dynamometer or high speed eddy current dynamometer rotor is optimized to meet the power and torque requirement of tested object under high speed condition.

 

  • The modal analysis of high speed dynamometer rotor ensures that the rotor resonant frequency is higher than the maximum speed.

 

  • The dynamic balance accuracy level of high speed dynamometer is improved.

 

  • Selection of special bearing to meet the high-speed requirement of high speed dynamometer.

 

  • Cooling optimization: High speed dynamometer absorbs power and changes as heat. Through optimizing cooling water flow channels, the cooling area of high speed hydraulic dynamometer or high speed eddy current dynamometer can be increased so that the heat can be timely discharged and evenly distributed. This can reduce the deformation of the dynamometer cooling chamber to ensure the life time of the dynamometer and reliability.

 

 

High speed dynamometer applications

 

  • High speed: For turbine testing, a cheap solution and as alternative to AC dynamometer
  • Low speed and large torque: As gearbox and transmission output end
  • Explosion protection: Suitable for special environment
  • Cooling method: Air cooling
  • Installation: Can be vertical installation, end-mounted, etc.

 

High speed dynamometer

 

Fundamentals of electromagnetic design

 

  • The principle of eddy current dynamometer: Electromagnetic induction and Lenz’s Law
  • Electromagnetic field CAE analysis: Electromagnetic optimization, rotor optimization

 

Dynamometer rotor dynamic design for turbo propeller test, turboshaft engine test

 

  • Lightweight rotor: Single rotor is changed to be small double rotor, weight and moment of inertia are only about 60% of the original while increasing the shaft diameter to improve rigidity
  • Critical speed: Modal analysis yields resonant frequency with rigid rotor system
  • Dynamic Balancing: Rotational vibration and stability
  • G1.0 balance (GBT 9239, ISO 1940, API standards, etc.)
  • Dynamic imbalance: around 0.5gmm

 

High speed dynamometer monitoring and diagnosis

 

Online monitoring

  • Vibration: bearing and vibration sensors
  • Temperature: Bearing, cooling chamber, inlet and outlet water with PT100 sensor
  • Flow: water inlet with electromagnetic flowmeter
  • Pressure: water outlet with pressure switch

 

Fault diagnosis

  • Vibration analysis: Time domain, frequency spectrum and wavelet analysis

Bearing and lubrication

 

  • High precision spindle bearings (light series): High speed
  • Bearing layout: Four bearing structure. Two pairs of bearings back to back with high rigidity
  • Lubrication: Special grease, oil-air lubrication, fuel injection lubrication
  • Bearing cooling: The cooling water channel is arranged in the bearing housing and cooling the outer ring directly
  • Real-time monitoring of temperature and vibration

 

Other design points for turbo propeller test, turboshaft engine test

 

  • Thermal optimization: Redesign the cooling channel to reduce thermal stress in the cooling chamber
  • Stress concentration for reducing heat distortion, reducing hot cracking and extending service life
