NT-GTF - New technologies for very low noise gear fan concepts
Overview
Background & policy context:
It is expected that the air traffic increases in future. For cost and environmentalism reasons, the fuel consumption of future airplane generations needs to be reduced. To achieve this objective, the engines should be more fuel efficient.
Objectives:
It is the objective to increase the efficiency of the airplane turbines.
The NT-GTF project focused on the following approach: To realize different numbers of revolutions in the turbine, a geared turbofan is implemented. The undocked and unattached numbers of revolutions obtain a higher efficiency. Furthermore, this concept can reduce the noise of the turbines significantly.
To apply the “geared turbofan”-concept in reality, the NT-GTF project focused on 2 issues: The research on new materials for weight reduction, and improvements in terms of Control engineering.
Methodology:
In a first step, the single components must be improved. But in addition, it is necessary to test the interaction of the different components. For a reliable result, tests on the ground and during flights provide realistic conditions. The NT-GTF project is divided into 3 work packages:
- WP1: GTF ground-/flight-test
- WP2: lightweight materials
- WP3: de-centralized control system
