Aircraft piston engine
Turbocharger rotor containment test method
1 Scope
This document describes the purpose and principle of the containment test for turbocharger rotors of aircraft piston engines and specifies the pre-test preparations.
Preparation, test implementation, test data processing and criteria and test report contents.
This document applies to containment testing of turbocharger rotors for aircraft piston engines.
2 Normative references
This document has no normative references.
3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Rotor
Turbocharger compressor wheel or turbine wheel.
3.2
Containment
The turbocharger housing withstands high-speed impacts from rotor fragments without being penetrated.
4.Purpose of the experiment
Verify whether the turbocharger housing has sufficient strength to accommodate the high-energy rotor when the rotor fails under extreme conditions
Fragments.
5 Test Principle
The high-temperature gas generated by the gas generator simulates the exhaust conditions of the engine and drives the turbocharger to rotate at high speed until the speed reaches
Above the specified minimum breaking speed, the rotor is forced to break, thus verifying whether the turbocharger housing can contain high-energy rotor fragments.
6.Preparation before the test
6.1 Test Outline
A test outline should be prepared before the test. The test outline should include the following contents.
a) Test basis;
b) Description of the turbocharger (including the configuration of the turbocharger, installation of the turbocharger on the test rig, turbocharger diagram
...
