The RB211 was a revolutionary turbofan engine featuring a triple-spool architecture. It was initially designed for the L-1011 but it also powered other aircraft such as the B747, B757 and B767. It also gave birth to the sucessful and technologically advanced Trent family.
The dash -22B was available for every standard length model while the -524B equipped the L-1011-385-3 (TriStar 500) and was an option for the following standard length models: L-1011-1-14 and L-1011-1-15.
