percent as compared to current generation

The BLADE programme will substantially
accelerate the development of future
laminar wing technology. The full laminar
wing fitted on the demonstration aircraft is
expected to deliver a 50 percent reduction
in wing friction, which could result in a
reduction of CO2 emissions by five percent.
Next generation jetliners developed
with such laminar flow wings will deliver
significant fuel efficiency improvements
over aircraft in-service today. It will also be
useful on the next generation of long-range
business jets.

Industry Participation
MTU Aero Engines is working within the
Sustainable and Green Engine (SAGE)
project and leads the subproject (SAGE-
4). The aim of this project is further
development of geared turbofan technology
(GTF) and it will run until 2017. The expected
benefits are reduced fuel consumption and
engine noise. From next year, 2017, as part
of Clean Sky 2, the project will build on the
results achieved so far. MTU plans to retain
a major role in the new programme and
will play a role in the design of an engine
demonstrator once more. According to
a company spokesperson, “During this
project, we hope to increase bypass ratios
in the engine and improve the thermal
efficiency of the core engine through
higher pressure ratios and temperatures
to produce an overall reduction of 25
