T.A.T F Engine – In Aircrafts 50% Fuel and Oxygen Savings With T.A.T F Engine


Description of the Project

Kod- T.A.T 103: Piston diesel engine for installing in aircrafts (Saving: 42%)

Kod- T.A.T 190: Making propeller system in propeller aircrafts efficient (Minimum Savings 10%)


Our company, ALKILINÇ TECHNOLOGY, aims to offer environmental friendly aircrafts which economize on fuel consumption and generate less air pollution to the service of people with 2 different projects on increasing efficiency and causing minimum 50% fuel savings in aircrafts.


Summary of the Kod- T.A.T 103 Project: Aircrafts will be transformed to propeller system, and piston engines, which were not durable in the past, will be made more durable and strong; the aircrafts will be more profitable with increase of the maintenance frequency to 4,000 hours (4,000 hours for turboprop engines) and will be used again, leading to significant fuel oil savings.


The engines designed within the framework of the T.A.T. 103 Project have 20 cylinders and will be manufactured to have up to 4,000 kW power. It will be possible to use these engines in aircrafts which have short, medium and long flight range, carry up to 200 people and fly at 700 km/h speed.


Average consumption:

Turboprop engines consume 315 gr/kwh fuel oil.

T.A.T Kod. 103 engines consume 180 gr/kwh fuel oil.


Consumption at full power:

Turboprop engines consume 370 gr/kwh fuel oil.

T.A.T Kod. 103 engines consume 220 gr/kwh fuel oil.


Comparative assessment:

Turboprop engines used in ATR-72-500 aircrafts (with capacity of 66 people) are 2 x 1,846 kW (2,475 hp) and consume 2.3 lt. fuel oil per km.

ALKILINC Kod- T.A.T 103 type 2 x 1,850 kW (2,480 hp) piston diesel engines will consume 1.3 lt. fuel oil per km.


As seen in this comparison, net savings of 42% is achieved when T.A.T 103 engines are used.


Information Note: The consumption data of the engines are applicable when engine is used at medium power. Aircrafts consume a little more as they take off at maximum power. After taking off, the power is reduced somewhat and fuel consumption is decreased by 10/20%. If diesel engines are used in aircrafts, biodiesel fuel can be used and this will lead to improvement in air pollution.


Summary of the Kod- T.A.T 190 Project: In propeller aircrafts, propeller pushes the air back and thus thrusts aircraft forward. During this process, propellers create centrifuge effect as they turn at high speed and push a part of the air outside. This means that less air is pushed back and causes efficiency loss.


In our Project, propellers are placed in a tube as in jet engines and the air normally pushed outside is carried to back and thus efficiency loss is prevented.


Project sponsors: Following 16 companies support the Clean aircraft project.

Joint Technical Proposal – Within the scope of the 2020 Framework Program and mutual cooperation, following 16 Clean Sky 2 Leader Candidates have joined their forces in 2012 with the parties that took part in the Joint Venture (CSJU) with support and coordination and signed the Letter of Intent.
