The central engine has a top-mounted intake for low boom, but inlet flow distortion due to vortices is a concern. [ 12 ] The flush cockpit means that the long and pointed nose-cone will obstruct all forward vision.

这架飞机的特点是能够以超过音速的速度飞行，同时减少音爆的噪音，为未来的商用民用超音速飞行开辟新的可能性。 X-59是NASA和洛克希德-马丁公司自2016年开始合作研发的 静音超音速技术 （Quiet SuperSonic Technology， Quesst）项目的成果。 该项目的目标是探索如何在不影响地面居民的情况下，实现超音速飞行。 自从2003年 协和式飞机 退役以来，超音速民用航机就消失在了天空中，主要原因是超音速飞机会产生巨大的音爆，对人类和环境造成干扰和破坏。 为了解 …

NASA近期选定使用F / A-18的传统声波吊舱在超音速飞行中测试CI-GRS。 这些测试将为美国NASA在测试其 X-59 的声学性能和城市社区飞越阶段测试噪声值提供借鉴。 几十年来，NASA一直致力于研究音爆，其噪声被认为是实现陆上商用超音速飞机未来的关键障碍。 当物体运行速度超过音速后，物体对空气的压缩无法迅速传播，会在迎风面积累形成激波面，激波面上的声学能量高度集中，这些能量传到人耳中，会产生极其强烈的爆炸声，被称为音爆。 美国政府在1973年做 …

美国宇航局的X-59这款飞机采用静音超音速技术，或称QueSST，这种实验性飞机，使该机构越来越接近于使陆地上的静音商业超音速旅行成为现实。 该航天局正在开发新的设计和所需的技术，以限制超音速轰鸣产生的噪音，使超音速飞机在飞越人口密集地区时能够超过音速。 而很快，这种由洛克希德马丁公司开发的飞机有望首次飞上天空。 这家公司预计为开发的这款飞机设计的地面噪音约为60分贝（A），它约为目前超音速飞机的1/1000。 这是通过使用长而窄的机身和鸭嘴来保 …

Instrumentation in the primary oxygen flow path includes a LOX quantity gauge and a pressure sensor upstream of the reducer, with both readouts available to the pilot. Having been regulated to the appropriate pressure based on the cabin altitude, the oxygen flow is routed by way

NASA’s Quiet SuperSonic Technology (QueSST) X‑59 is an advanced low-boom aircraft concept that will be used to emulate and test noise generated by future supersonic over-land transport designs.

Abstract: The paper presents the calculation results of the flow features and longitudinal aerodynamic characteristics of the NASA X-59 QueSST low boom demonstrator. When developing a perspective supersonic civil aircraft, it is necessary to apply reliable methods for calculating aerodynamic characteristics.

The HSIDT successfully collected high response distortion data points for the X–59 from Mach = 0 to 1.55 for a wide range of angle-of-attack, angle-of-sideslip, and inlet flow. Analyses showed that inlet dynamic distortion and inlet planar wave (or inlet buzz) were within engine limits through most of the flight envelope.

2020年3月25日 · NASA’s production-level Cart3D simulation package for CFD has been used extensively to determine the pressure field near the aircraft and evaluate the ground noise carpet of each major design evolution of the X-59.
