Turbounion is an international company formed in 1969 to coordinate the construction of the RB-199 engine, manufactured in collaboration with Rolls-Royce, MTU, and Fiat.

“RB-199 introduced in 1972”

-The RB-199 was the engine chosen for the Panavia Tornado.

-The initial models were the Mk101 and Mk103, which would later be developed into the Mk104 and Mk105, with a power output of nearly 17,000 lbf (17,000 hp).

“RB-199, cutaway”

-Turbounion, or MTU (see also), builds the MTM-385, a 1,200 shaft hp helicopter engine.

“MTM-385”

- This is the consortium created by Rolls-Royce, MTU, and Fiat to build the RB199-Mk-103, 104, and 105 engines for the Panavia Tornados owned by these same countries.

- Approximately 850 aircraft have been built.

- A total of 930 engines were delivered.

-The delivered around 76 kN of thrust with afterburner, triple-shaft, and dual-flow.

- The shafts were the fan at 12,000 rpm with two turbines, the low-pressure compressor (LP) at 15,500 rpm with one turbine, and the high-pressure compressor (HP) at 19,000 rpm with one turbine.

From Appendix 9: Engine developed by several countries for the Tornado aircraft. This is the RB-199 (Rolls-Royce B design). See main text.

-At the Munich museum, there is a cutaway one. It is a by-pass type with afterburner and has the reverse flaps half-open. When fully retracted, they fit on the engine in a streamlined way.
