DEVELOPING NEW REDUCTION TECHNOLOGY REGARDING NOISE, WEIGHT
AND EMISSION OF CO2 FOR AIRCRAFT ENGINES
ENVIRONMENT FRIENDLY AIR-FEED JET

 

Contract: AST 3 - CT - 2003 – 502790

INCDT COMOTI contribution:

CALCULATION OF TURBULENT FLOW IN COAXIAL JETS USING REEL FILAMENT METHOD (VFM) AS INPUT FOR NOISE CALCULATION

 

AIRPLANE ENGINE NOISE REDUCTION - A NEW TECHNICAL SOLUTION: CRTF counter rotating fan

 

RESULTS COMPARING AGAINST CLASSIC SOLUTION: SR single rotor fan

Benefits:

- on airship noise reduction with 6 db in the first phase and with 4 db in the second phase, according to ACRE
- CO2 emission decrease with 7% in the first phase and with 11% in the second phase
- airplane engines weight reduction with 20%
