Variants

The TF34 is the military version that is used on the A-10 Thunderbolt and the S-3 Viking. It was developed during the late 1960s through the engine division of General Electric. The original engine includes a single stage fan, which is driven by a four-stage low pressure turbine, a 14 - stage high-pressure compressor, is driven by a two-stage high pressure turbine, and an annular combustion chamber. The TF34 -GE -400A is approved for a thrust of 41.26 kN.

The civil variant CF34 ( ' Commercial Fan' ) is in various commercial aircraft, including Bombardier CRJ series, the E-Jets Embraer and of the developing Chinese ARJ21 used. Originally, the CF34 is based on the TF34. It was first used in 1983 as CF34 -3A on the Challenger 601 corporate jet. Later versions of the CF34 with higher thrust have a new core with only zehnstufigem high-pressure compressor. This 8C1 CF34 was approved in November 1999 by the FAA and used as of 2001 in CRJ700. The latest versions, the 10A -10E and are derived from the CFM56- family have a basic modified high-pressure system and including a nine -stage compressor which is driven by a single stage turbine. The low pressure system has Approved additional three booster stages behind the fan, these variants are for a boost of up to 88.9 kN.

From the CF34 are now more than 6000 pieces worldwide in service, of which 4300 piece on regional jets. With the technology programs NG34 and TechX GE is currently working on a follow-up model, which save about 20 % fuel and 2012 is supposed to have its first run.
