Air Turbine Starter Test Bench

Key features

Key components and functions

Unit Under Test (UUT) mounting: A dedicated trolley or fixture for securely mounting the starter to be tested.
Dynamometer: A water brake dynamometer is often used to apply a load to the starter, allowing it to be tested under different pressures and rotational speeds.
High-pressure air supply: Provides the compressed air needed to spin the turbine, which is controlled to simulate various operating conditions.
Measurement and control: The bench is equipped with sensors and a control system to measure and display performance data, including:
- Rotational speed: Measured by a laser tachometer or other speed sensors.
- Pressure: Monitors air pressure supplied to the starter.
- Torque: Measures the rotational force produced by the starter.
- Frequency and voltage: Some systems monitor electrical characteristics, such as frequency and voltage.
Safety features: Built-in safety measures like emergency stops, acoustic enclosures, and fire suppression are common to protect personnel and equipment, especially for systems connected to fuel and high-pressure air.

Data logging and automation: The system records test results for analysis and may include automated reporting features.
