“Supersonic flow” Science-Research, November 2021 — summary from NASA Technology Transfer Program

NASA Technology Transfer Program — summary generated by Brevi Assistant

Scientists at NASA’s Armstrong Flight Research Center and Ames Research Center have created an innovative approach for recording photos of shock waves originating from aircraft in supersonic flight. NASA has established a unique approach to render noticeable the thickness changes in air that cause a refractive index adjustment by an air-borne vehicle. NASA’s Langley Research Center establishes ingenious technologies to control fluid flow in manner ins which will inevitably lead to boosted efficiency and fuel performance. NASA uses 2 new fluidic oscillator layouts that address. Trendsetters at the NASA Langley Research Center have established a system for predicting sonic boom propagation of supersonic aircraft, the sBOOMTraj tool. SBOOMTraj has potential applications in the design and advancement of next generation supersonic airplane, and may additionally allow pilots and drivers of such airplanes to prepare flight paths to decrease their sound impacts. NASA’s Langley Research Center has created a technology that is predicted to prolong the laminar flow area over supersonic flight setups by postponing the shift of limit layer flow from laminar to rough state. It can be utilized in combination with many of the existing techniques for passive and active laminar flow control, but is especially appropriate for a supersonic natural laminar flow design by virtue of avoiding the space, weight, system complexity, and maintenance fines connected with suction based laminar flow control. Requirements second-throat and cylindrical diffusers permit supersonic gas moves to increase within their walls and draw a vacuum cleaner on any kind of upstream void. A new sort of spike diffuser recently created by NASA Stennis Space Center has the ability to give around double the pumping performance of second-throat diffusers by means of Pareto-efficient reduction of both core Mach number and flow deflection.
