The thermal design parameters of space telescopes are mainly optimized through traversal and iterative attempts. These optimization techniques time consuming, rely heavily on the experience engineer, bear a large computational workload, have difficulty in achieving optimal outcomes. In this paper, we propose method (called SMPO) based an improved back-propagation neural network GAALBP) that builds surrogate model uses genetic algorithm to optimize parameters. telescope measures atmospheric...
Concentration probes are employed in supersonic flow mixing measurements. Because the typical design of such is essentially based on an inviscid, adiabatic, quasi-1D analysis, scope this work to understand better and quantify severe impact viscous effects probe's internal gasdynamics associated uncertainties measured quantities via a computational fluid dynamics analysis. Specifically, focus augmented errors due aforementioned when coupled with various cases probe-flow misalignment, which...
Cosmogenic beryllium-10 and beryllium-7, the ratio of two (10Be/7Be), are powerful atmospheric tracers stratosphere–troposphere exchange (STE) processes; however, measurements sparse for altitudes well above tropopause. We present a novel high-altitude balloon campaign aimed to measure these isotopes in mid-stratosphere called Beryllium Isotopes Resolving Dynamics Stratosphere (BIRDIES). BIRDIES targeted gravity waves produced by tropopause-overshooting convection study their propagation...
The present work details the preliminary analysis and design of a model scramjet combustor intended to serve as research platform for mixing combustion studies in support current non-reactive research. shock tunnel located at Aerodynamics Research Center University Texas Arlington, capable producing test conditions simulating flight Mach numbers ranging from ~5 ~16 altitudes ~24 km ~85 km, will facility combustor. Specifically, modular allow study supersonic flameholding characteristics...
