Objective
Objectives and content
The principal aircraft and engine manufacturers in Europe
are facing increasing pressure to reduce aircraft noise
levels. This arises both from the community expectations
of improved quality of life and from the need to
compensate for the expected growth in air traffic. A
recent EC DGXII policy statement on aircraft noise
declares: "a co-ordinated strategic approach at European
level is essential and major efforts need to be devoted
to techniques for further reduction of exterior aircraft
noise to overcome today's technology barrier. Hence the
objective for R&D is to enable a breakthrough in noise
control technology".
The objective of RESOUND is to acquire the technology
necessary to support the design of derivative and new
aero-engines with noise levels that are 4 dB quieter than
those of aircraft currently entering service. This will
provide the foundation for the achievement of a mid-term
(8 years) objective of reducing aircraft noise levels by
at least 6 dB, and allow European industry to compete on
an equal footing with the US.
RESOUND addresses the challenge of reducing the noise at
source, in particular turbomachinery noise, through (1)
engine component aeroacoustic design and (2) through
novel noise controlling devices that can be integrated
within the engine structure. Innovative technologies to
be evaluated, with the aid of theoretical techniques and
experiments at model and full scale, include:
fan noise reduction through reduced tip speed and
pressure ratio optimisation
noise reduction with fan and stator axial sweep and
circumferential lean
fan noise reduction with variable by-pass nozzle and
passive fan tip treatments
combustion noise reduction through improved and
validated generation and propagation model
assessment of potential noise hazards of low NOx
combustors
LP turbine noise reduction through exit guide vane
design
turbomachinery noise reduction through active stator
design
turbomachinery noise reduction by means of auxiliary
aeroacoustic control devices.
Based on the technology acquired, RESOUND will deliver a
full assessment of the community noise benefits of
controlling engine noise at source, through design and
with novel active/passive devices.
The reduction of aircraft noise through improved nacelle
technology and airframe design is being addressed by
complementary proposals (RANNTAC and RAIN respectively),
supported by two Type 2 proposals (DUCAT and FRAIN) all
of which will be co-ordinated through the X-NOISE
thematic network that has been formed as a result of the
Environmentally Friendly Aircraft study (TEFA). Such a
combined effort is necessary to meet the challenge of the
US industry, which is backed by a fully funded program
(200 MUSD over 7 years).
