The achieved result

Gasturbine engine

The improving of engines fan effectiveness 

The
increasing in the fan efficiency up to 3% was achieved by optimal
profiling of its blades vanes and passage, which allowed to have
the optimal distribution of compression work between the stages
and by the radius. Dimensionality  up to 63.

The improving of engines fuel economy at throttled
operating modes 

The optimal control laws of engines passage controllable
elements were obtained, which allowed to decrease the specific fuel
consumption at throttled operating modes up to 8% due to optimal coordination
of engines functional elements work. Dimensionality  up to 14. 
The decreasing of engines acceleration time 

The optimal time control laws of passage controllable
elements were achieved, which allowed to decrease the acceleration
time 1.5 times as less due to optimal coordination of all control
efforts during transitional process. Dimensionality  20. 
Multistage axial flow compressor for engine with
high bypass ratio

The improving of the high pressure compressor effectiveness 

The high pressure compressor efficiency was increased by 1.5% due
to its optimal profiling. The rise of effectiveness was reached
due to optimal coordination of gasdynamic parameters of work of
elementary vanes in a system of the compressor. Dimensionality 
up to 96.

The improving of middle pressure compressor effectiveness 

The middle pressure compressor efficiency was increased
by 1.7% due to optimal control laws of its stator blades. The optimal
structure of compressors stator blades control was determined. The
rise in effectiveness was provided by optimal distribution of compression
work between compressors stages. Dimensionality  5. 
Heat machine

Remaking of aircraft engine without operational resource
in heat machine with minimal modifications 

The fuel economy of heat machine was improved by more
then 10%. Optimal coordination of components of engines without operational
resource was carried out for their operation in a complex of heat
machine. 
The technological process

Improving of metal structures welding technologies 

Just in industrial process due to optimal coordination
of 13 technological parameters the improving of strength indicators
of metal structures welded joint by 14% was achieved. 
Gasturbine engine with high bypass ratio

The increasing of engines fan effectiveness at engines
takeoff and cruising operating modes simultaneously 

The means was proposed to increase fans rotor efficiency
by 2.5% for engines takeoff o
