ABSTRACT:The interaction of high Mach flows with the aircraft and engine structures generates complex fluid dynamic phenomena that include shock waves, shear layers, vortices, and separated flows, all of which can be further influenced by the thermochemical behavior of the high-temperature air. These fluid phenomena affect high-speed inlet operability and performance, but are not well understood, nor modeled. As such, inlet development often incorporates parametric testing of active and passive flow control approaches, such as boundary layer bleed. ?Currently parametric inlet bleed testing suffers from manual implementation of selectively filling or opening holes in plates with large array of holes. ?Our proposed solution automates the process by introducing a parametric bleed interface that has embedded flow metering and control for each bleed hole. ?The system replaces the current setup with one that allows remote, automated, real-time variation of bleed pattern and flow variance without any tunnel downtime, and with continuous monitoring of operational performance discretely for each bleed hole to eliminate run time uncertainties. ?A preliminary design of the miniaturized parametric bleed interface unit will be delivered at the end of the Phase I effort, supported by analysis and risk reduction testing.BENEFIT:Real-time, automated implementation of parametric inlet bleed without tunnel downtime ?Integrated flow metering and control for each bleed hole enabling flexible bleed pattern and discrete flow variation ?Faster, less expensive development of high-speed inlet configurations in support of growing market needs ?Derivative applications to embedded flow control for engine applications ?
