E-A-R Specialty Composites.E-A-R Specialty Composites announced that the company's high performance aircraft damping damping In physics, the restraint of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipating energy. Unless a child keeps pumping a swing, the back-and-forth motion decreases; damping by the air's friction opposes the composites were selected by Raytheon for soundproofing Soundproofing is any means of reducing the intensity of sound with respect to a specified source and receptor. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to block or absorb the energy of the sound treatment in the first four Boeing business jets The Boeing Business Jet series are factory conversions of Boeing airliners for the corporate jet market, initially the 737 series airliners. This aircraft usually seats between 25 and 50 passengers within a luxurious configuration. delivered by Raytheon's Aircraft Integration Systems business unit. |
