COMMERCIAL AIRCRAFT NOISE PROBLEM
The history and future developments of commercial aircraft noise are discussed. The use of the turbofan engine to replace the louder turbojet engine is identified as a step forward in reducing noise. The increasing use of two engine planes for medium and even long hauls is seen as a positive trend. An increase in the number of aircraft movements is predicted. An upturn in noise exposure around the end of the century is predicted. The development goals of Rolls Royce in meeting the noise reduction challenges of the next decades are discussed.
