NASA's X-59 quiet supersonic research aircraft has taken another successful step toward flight with the conclusion of a series of engine performance tests. In preparation for the X-59's planned first flight this year, NASA and Lockheed Martin successfully completed the aircraft's engine run test...
装有“安静长钉”并进行低声爆修型的超声速公务机与协和和未经修型的同尺寸飞机的声爆波形对比图(图片来源:An Overview of the Gulfstream Supersonic Technology Supersonic Technology Program) 常规而言,飞行器在超声速飞行时产生的激波大体上由一前一后两道强烈的激波组成,分别来自空气被机身冲击和离开机身时引发...

直连式超声速燃烧实验台(Direct-ConnectSupersonicCombustionTestFacility)于1969年开始服役,用于超燃冲压发动机燃烧室地面实验。采用烧氢补氧的方式提供燃烧室入口来流,模拟状态对应的自由飞行状态为马赫数4~7.5。燃烧室后能够容纳尾喷管,可以对“燃烧室+喷管”进行整体实验。实验台的整体布局如图9。

wind tunnel to which a negative pressure is appropriately applied, the flow through the test section of the wind tunnel can be made uniform over a range of different transonic and supersonic velocities. The invention therefore includes apparatus in combination with that described for varying the ...
(505 million kilometers) of interplanetary space if you can't stick the landing. At 70.5 feet (21.5 meters) in diameter, the rover's supersonic parachute has everything to do with making that happen. A lot of work goes into ensuring a chute deploys right and can do the job without ...
And in a world "first," another X-plane will be a business-jet-sized supersonic vehicle that burns low carbon bio-fuels and generates such quiet sonic booms that people on the ground will barely hear them. This truss-braced wing concept could be another subsonic X-plane; the supported win...
