Estimating the term…
The present application concerns a test engine hood for a turbine engine, such as a double flow turbine. The test hood allows replacement of a flight engine hood during tests on a test bench on the ground where the temperature conditions could damage the flight hood. The test hood includes a tubular wall of carbon-fibre epoxy composite, and metal flanges upstream and downstream. To provide thermal protection, the test hood includes a layer of silicone with a majority of polysiloxane. The layer covers the entire inner surface of the wall to create a barrier. The present application also concerns a method for testing a turbine engine on a test bench, where the turbine engine is fitted with a test casing. The present application also concerns a use of silicone for thermal insulation of the inside of the test hood of the turbine engine on a test bench on the ground.
A test engine hood for a turbine engine, the test engine hood including an annular duct for an annular flow, and being configured to replace a flight engine hood of the turbine engine during a test of the turbine engine on a test bench, the test engine hood comprising:
A test engine hood for a turbine engine exhibiting an annular duct for an annular flow, the test engine hood being configured to replace a flight engine hood of the turbine engine during a test of the turbine engine on a test bench, the test hood comprising:
A method for testing a turbine engine on a test bench, the method comprising:
