The Rolls-Royce Turbomeca Adour is a twin-shaft turbofan engine that was developed by Rolls-Royce Turbomeca Lmt., A joint subsidiary of Rolls-Royce ( Great Britain ) and Turboméca ( France ). It is named after the Adour River in southwestern France.

history

The Adour was developed primarily for the SEPECAT Jaguar fighter-bomber . The first successful tests took place in 1968. It is produced in different versions with or without an afterburner .

By July 2009, more than 2,800 engines of this type had been built and delivered to over 20 different armed forces. In December 2009 it achieved a total of 7,000,000 flight hours. The US military uses the engine in the T-45 Goshawk under the designation F405-RR-401.
