Study on the Similarity Criteria of Aircraft Structure Temperature/Stress/Dynamic Response

open access: yesJournal of Thermal Science and Technology, 2012
The performance parameters of thermal protection system are essential for the design and optimization of high-speed aircraft. The flight-ground conversion is a valid method to provide the effective support to the design of the thermal protection ...

Regression analysis to evaluate herbicide drift and injury in Roundup Ready cotton in wind tunnel

open access: yesRevista Ciência Agronômica, 2021
The aim was: (i) to propose a regression model for the association between injury in Roundup Ready (RR) cotton plants and drift of auxins, isolated or associated with glyphosate; (ii) to evaluate the effect of adding glyphosate to dicamba and 2,4-D ...

A Wind Tunnel Simulation Facility for On-Road Transients [PDF]

open access: yes, 2014
This paper outlines the creation of a facility for simulating on-road transients in a model scale, ¾ open jet, wind tunnel. Aerodynamic transients experienced on-road can be important in relation to a number of attributes including vehicle handling ...

Experiment and Simulation Effects of Cyclic Pitch Control on Performance of Horizontal Axis Wind Turbine

open access: yesInternational Journal of Renewable Energy Development, 2017
Offshore wind is generally stronger and more consistent than wind on land. A large part of the offshore wind resource is however located in deep water, where floating wind turbines can harvest more energy. This paper describes a systematic experiment and

Aerofoil behaviour at high angles of attack and at Reynolds numbers appropriate for small wind turbines [PDF]

open access: yes, 2014
The aerodynamic characteristics of a NACA0018 aerofoil have been investigated experimentally for incidence angles ranging from 0° to 180° in closed-jet and open-jet wind tunnels with different blockage coefficients at Reynolds numbers from 60,000 to 140 ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...
