A quick surface heat flux estimation method for typical structures of high-speed aircrafts
نویسندگان
چکیده
Abstract Surface heat flux estimation of high-speed aircrafts is an inverse problem and high system ill-posedness usually leading to instability low accuracy. In this study, efficient method proposed solve it stably. The identification equation established based on the superposition principle. Tikhonov regularization with parameter determined by generalized cross validation applied reduce sensitivity measurement error. A calibration presented correct pulse coefficient matrix so that can be used for complex three-dimensional structures. Numerical studies demonstrate efficiency

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Surface renewal method for estimating sensible heat flux
For short canopies, latent energy flux may be estimated using a shortened surface energy balance from measurements of sensible and soil heat flux and the net irradiance at the surface. The surface renewal (SR) method for estimating sensible heat, latent energy, and other scalar fluxes has the advantage over other micrometeorological methods since the method requires only measurement of the scal...

متن کاملA Hybrid Method for Measuring Heat Flux
This paper reports on the development and evaluation of a novel hybrid method for obtaining heat flux measurements. By combining spatial and temporal temperature measurements, it is shown that both the time response and accuracy of a heat flux sensor can be improved. This hybrid method was shown to increase the time response of a heat flux sensor mounted on a high conductivity material by a fac...
