A specific range of test equipment

The special equipment placed on an aero-engine in its test cell, directs the air stream and reproduces conditions close to those of an engine in flight.

Under the name EoLines®, Safran Aero Boosters markets a wide range of specific test equipment used for engine testing in indoor and outdoor facilities.


We have designed and built EoLines® products for the leading engine manufacturers such as Engine Alliance, General Electric, Pratt & Whitney and Safran Aircraft Engines, ensuring that it is present in most civil and military engine programmes. We also work for maintenance and repair centres, armed forces and commercial airlines.
