Turboshaft 1,200 shp Gas Turbine Engine

Project 1221 has opted to develop in-house its own gas turbine engine technology and is due to introduce to the market a novel engine configuration with Vaneless Counter-Rotating Turbine, particularly for the 800 shp - 1,200 shp class (turboshaft and turboprop versions).

The novel design of the engine allows in particular the variation of the engine cycle through the variation of the RPM of the power turbine.

The ability to regulate the cycle of the engine provides increased capability and a series of advantages in comparison with analogous engines, because it allows to establish an optimum combination of cycle parameters for a variety of engine operating conditions.

Notably, the Project 1221 automotive/marine turboshaft gas turbine engine has the unique capability to deliver the same performance as a conventional gas turbine engine of 50% larger capacity, while employing a transmission of 80% smaller capacity.

Thanks to a double power take-off, our automotive/marine turboshaft can be combined at the same time with a conventional gearbox as well as with an electric generator/motor or air turbine, offering great flexibility (hybrid and zero-emission capability) and the opportunity to pursue different applications, with exceptional cost and weight reductions.

SPECIFICATION
Power: 800 shp (nominal) - 1,200 shp (maximum)
Torque (maximum): 1,431 Nm
RPM of output shaft: 8,000
RPM of compressor turbine: 41,000
RPM of power turbine: 26,300
Dimensions: width 390 mm, height 390mm, length 800 mm
Weight: 110kg

Indeed, all engine versions (turboshaft, turboprop and turbofan) present comparatively lower weight and smaller overall dimensions, a lower number of complicated and expensive components, a longer service life, lower service costs, greater reliability and increased capability to maintain constant power.

Turbofan 6kN Gas Turbine Engine

Besides adopting these powerplants ourselves for our own upcoming vehicles, craft and aircraft, it is our intention to commercialize them as well, as soon as possible.

In fact, Project 1221 would consider forming an alliance with a major industrial or financial partner in order to fully exploit the commercial potential of the described engine technology, concerning the automotive/marine turboshaft and in particular the aero turboshaft, turboprop and turbofan variants, for all kinds of applications.
