“Supersonic flow” Science-Research, February 2022 — summary from NASA Technology Transfer Program
NASA Technology Transfer Program — summary generated by Brevi Assistant
Researchers at NASA’s Armstrong Flight Research Center and Ames Research Center have developed an innovative strategy for recording photos of shock waves rising from aircraft in supersonic flight. NASA has established a unique technique to render visible the density changes in air that create a refractive index modification by an airborne vehicle. NASA’s Langley Research Center develops ingenious innovations to control fluid flow in means that will eventually result in boosted performance and gas effectiveness. NASA supplies 2 new fluidic oscillator layouts that resolve. Innovators at the NASA Langley Research Center have created a system for predicting sonic boom propagation of supersonic airplane, the sBOOMTraj tool. SBOOMTraj has possible applications in the layout and growth of future generation supersonic aircraft, and might also make it possible for pilots and operators of such aircraft to prepare flight paths to lower their sound footprints. NASA’s Langley Research Center has created a technology that is predicted to expand the laminar flow location over supersonic flight setups by delaying the change of limit layer flow from laminar to rough state. It can be used in combination with a number of the existing techniques for passive and active laminar flow control, however is specifically fit for a supersonic natural laminar flow style because of staying clear of the space, weight, system complexity, and maintenance fines associated with suction based laminar flow control. Requirements second-throat and round diffusers enable supersonic gas flows to increase within their wall surfaces and pull a vacuum cleaner on any type of upstream space. A new kind of spike diffuser recently developed by NASA Stennis Space Center has the ability to supply around double the pumping efficiency of second-throat diffusers via Pareto-efficient reduction of both core Mach number and flow deflection.
