NASA’s X-59 Quiet SuperSonic Technology X-plane is designed to fly faster than the speed of sound without producing sonic booms – those loud, startling noises which can be disruptive to humans and animals. Currently, commercial aircraft aren’t allowed to fly faster than the speed of sound over land because of the objectionable sonic booms they cause for those on the ground. This experimental plane will fly at a cruise speed roughly double that of a commercial jet while keeping aircraft noise down to a quiet “sonic thump” – or even no sound at all – as heard on the ground when the plane flies overhead at supersonic speeds.

To be sure the X-59’s design will perform within expected noise limits, NASA is working closely with its contractor, Lockheed Martin, to create a database of computational fluid dynamics simulations to verify the aircraft’s supersonic performance. The database will include simulations for all possible combinations of the settings that a pilot uses to control the aircraft and the flight conditions that may be encountered during flight.

为了确保X-59的设计能在预期的噪声范围内运行,NASA正与其承包商洛克希德·马丁公司(Lockheed Martin)密切合作,建立一个计算流体动力学模拟数据库,以验证飞机的超音速性能。该数据库将模拟飞行员用来控制飞机的所有可能的设置组合,以及飞行过程中可能遇到的飞行条件。
