The TWIN PISTON ENGINE SYSTEM or T.E.P.S. – the RAP 9890 evolution presents itself as a single unit projected to be the rational integration of two engines-completely independent of each other, able to work in synchronization but also to function singularly when needed, although co-existing in one engine body.

Each engine has redundant ignition and fuel supply so as to guarantee high reliability standards in aeronautical applications.
The TEPS project obtained the SEAL OF EXCELLENCE by the European Commission in phase 1 "SME Instrument" of HORIZON 2020.
