YIP Plasma Surface Interactions of Thermally Intense Aerospace Surfaces
Abstract
The proposed project will use an analytical and computational methodology approach that will also perform highenthalpy arc-jet experiments for model validation and assessment. Specifically, the answers to three fundamental -science questions will tackle the problem of whether thermionic emission can manage thermally intense aerospace -loads: (Question 1) #How do the emitted electrons behave in collisional and hypersonic environments?#; (Question -2) #What are the conditions for and limits of surface cooling of a hypersonic leading edge with thermionic -emission?#; and (Question 3) #How does an ionized and thermionic flow behave in a hypersonic flow field?# Three -research objectives will address Questions 1 through 3 and test the hypothesis. Research Objective I: Predict the -level of thermionic emission, heat transfer, and power generation from hot surfaces in collisional and hypersonic -environments. Research Objective II: Investigate mechanisms to maximize cooling power of a hypersonic leading -edge with thermionic emission. Research Objective III: Investigate vehicle effects of thermionic emission and -ionized flows. Overall, this YIP will investigate how plasma and emitted electrons behave on the plasma sheath -scale, leading edge scale, and vehicle scale to finally determine whether thermionic emission is a viable method -of managing the heat loads on hot aerospace surfaces such as leading edges of hypersonic vehicles.
