100 - 300hp piston engine GF56

100 - 300kgfor general aviation2-stroke

GF56 engine is suitable for General Aviation market (CS23 and FAR23 aircraft range). It’s a retrofitting engine and can be installated on aircraft currently using Lycoming and Continental engines. It’s fully designed by an internal high qualified engineers team of CMD to ensure accurate manufacturing process control, production cycle and continuity airworthiness. MAIN FEATURES AVIO GF56 is a diesel common-rail direct injection engine, 2-strokes uniflow, 5 cylinders boxer, liquid cooling system, 5600cc., “direct drive” transmission. Applications General Aviation; RE-engine market; “Rotary wing” segment; Unmanned Aircraft. GF56 is a project which has transposed all innovations available in the engines for general aviation field, while trying to always pursue an aeronautical philosophy. The injection electronic control related to turbo-supercharging and in terms of components’ efficiency, involves the choice of liquid cooling system that, compared to air cooling, allows optimal thermal load control for disposal and better management of cooling at altitude changes. All mechanical and fluid dynamics are made by CMD and completely independent from existing engines. GF56 has a Roots compressor and a pressure blower per bancata which they are in series in a first phase and then in parallel. The Roots compressor just need in a first phase for washing (as two-stokes uniflow) and then the biggest contribution is made by pressure blower at a maximum power. At maximum torque the efficiency is greater than 40% and the energy consumption is 220 g/kWh.
