Among these engines are pW6 with a thrust of 4.0 kN and Gp7200 with a thrust of 362.5 kN. Two of the engines were certified in the fall of 2004 and the others will collect evidence by the end of 2007. All nine engines are based on the latest technology, but the emphasis is different, with some focusing on reducing the number of parts Some are using new materials as a selling point, but one thing is common, these engines have been designed from the first day to consider the maintenance of sex.
