Preliminary design of the Aviadvigatel PD-14 engine for United Aircraft's MS-21 twin-jet has received approval following review by a technical advisory council.

The turbofan is being developed to give customers a choice in fitting MS-21s with domestically-built or foreign engines. United Aircraft has selected the Pratt & Whitney PW1000G as a baseline powerplant for the type.

United Engine Corporation says it has reviewed the project from the critical 'gate two' development stage. People close to the matter say this was focused on determining major system manufacturers and outlining a co-operation scheme.

Perm Motors will be responsible for producing hot core sections and carrying out engine integration, while the Ufa-based firm UMPO is to supply low-pressure modules for the PD-14. The project also envisages participation of engine manufacturers NPO Saturn and Salyut, with their responsibilities yet to be specified.
