Sonic Boom Consideration in Preliminary Design of Supersonic Aircraft SONIC BOOM ACCEPTABILITY - HISTORY OF SUPERSONIC RESEARCH - QSP SONIC BOOM RESEARCH HISTORY The sonic boom, which in the s was an interesting but little-recognized phenomenon, has since become a major concern in the operation of military. • Low Sonic Boom ~psf • Long Range ~5,nmi • Low noise – Stage 4 compliant • Weight ~, lbs • Good Low Speed Aero ~7, TOFL • High Cruise Performance • Low Fuel Burn Rate Viable Low Boom Aircraft •Lower weight supersonic business jets have the best chance to meet potential stringent over-land sonic boom requirements. Transport (SST) Program and the follow-on Supersonic Cruise Aircraft Research (SCAR) Program funded studies of design, performance, maintenance, and marketing problems. When the engine-nacelle location was changed, it was usually for a specific reason. One such reason was the reduction of the aircraft's sonic-boom on the ground. Sonic-boom. Sonic Boom Testing for Future Supersonic Aircraft | NASA Langley Aviation Science Video individuals from the local community are invited to listen to sounds similar to aircraft .
The sonic boom needs to be quieter, and so do the engines if the plane is going to fly out of any commercial airports. to design a commercial aircraft for supersonic cruise flight and make it Author: Jay Bennett. of Sonic Boom Suppression Excellent Correlation & Validation of Sonic Boom Suppression.

Coupled with NASA and USAF sonicboom research of the late fifties and sixties, the FAA entered the sonic-boom- research arena by participating inCited by: 3. Sonic boom Filed under: Shock waves Vector Polar Method for Shock Interactions With Area Disturbances (technical note DR 4; Berkeley: University of California, ), by Antoni K. Oppenheim and Paul A. Urtiew (page images at HathiTrust).
Tests, however, have shown that structures in good condition have been undamaged by overpressures of up to 11 lb. Sonic booms produced by aircraft flying supersonic at altitudes of less than feet, creating between 20 and lb overpressure, have been experienced by humans without injury. Sketch of near and far ﬁeld shock wave patterns of a supersonic aircraft. Sonic boom is the ground signature of the pressure shock produced by an aircraft ﬂying at supersonic speed . NASA has awarded a contract to build an experimental supersonic aircraft - known as an X-plane - that reduces a loud sonic boom to a gentle thump. Read more. The energy range of sonic boom is concentrated in the - hertz frequency range that is considerably below that of subsonic aircraft, gunfire and most industrial noise. Duration of sonic boom is brief; less than a second, milliseconds seconds) for most fighter- sized aircraft and milliseconds for the space shuttle or.
