In railroad tracks, rail ties hold the rails in place and ensure that their separation does not change. Modern concrete ties warp and crack through repeated use, leading to safety concerns including ...

Having a home near a busy airport certainly has its perks. It is close to many establishments and alleviates the problem of wading through endless traffic to catch flights. But it does come at a cost ...

When speaking of electric aircraft, one of the most talked about benefits is a reduced noise level, compared to standard airplanes. But there’s still a long way to go until electric air mobility ...

Although an airliner's engines may be quite loud on takeoff, its wings also create a lot of wind noise when it's landing. According to a new study, the latter problem could be addressed with the ...

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although ...

Abstract: The return of commercial supersonic flight requires innovative solutions to be developed that meet noise and efficiency requirements for overland flight. To study such a possibility NASA is ...
