VZLU helps the development of a new turboprop engines

In recent period, the media reported that GE Aviation signed a long-term cooperation agreement with the Czech Technical University in Prague (CTU), where GE Aviation will help CTU to build and operate a new test infrastructure. As part of these activities, CTU also cooperates with the Czech Aerospace Research Centre (VZLU) from Prague and Orbis Avia, a company from Hradec Králové.

The VZLU´s site in Prague became one of the locations where CTU placed its engine test rig with the Catalyst engine from GE Aviation. CTU researchers will use the engine and its 800-channel test rig to develop a database of predictive maintenance requirements for individual turboprop engines. VZLU provides CTU with test facilities for the placement of test containers and assists with the complete integration of the engine test chamber. The provision of VZLU technical staff for the testing campaign and test rig maintenance is also an important part of the cooperation within this project. The VZLU staff complements the international development team of professionals from CTU, GE Aviation and Orbis Avia. In addition to the above-mentioned activities, the next priority for VZLU and CTU is education of a new generation of engineers and technicians with a focus on aircraft engines.

Concerning the new engine Catalyst, GE Aviation states that this is a brand new 16:1 compression engine with a 20% lower fuel consumption. The engine belongs to general aviation engines range of 1000-1600 shp. The engine and the propeller are controlled electronically by FADEPC (Full Authority Digital Engine and Propeller Control). The GE Catalyst engine design foresees a service interval of 4,000-6,000 flight hours. The final certification of the engine is planned for 2020. The Cessna Denali is to be the first aircraft to be powered by the new Catalyst engine developed by GE Aviation.
