The prediction of transonic loading advancing helicopter rotors [PDF]
Two different schemes are presented for including the effect of rotor wakes on the finite-difference prediction of rotor loads. The first formulation includes wake effects by means of a blade-surface inflow specification.

Predicting the wake structure of the HART II rotor using the vorticity transport model [PDF]
, 2008 Brown’s Vorticity Transport Model has been used to predict the wake structure and resultant blade loading of the rotor that was studied during the HART II experimental programme. The descending flight condition of the experiment yields significant high-

One day of environment‐induced heat stress causes injury to the murine kidney
Experimental Physiology, EarlyView.Abstract Environment‐induced heat stress (EIHS) results from sustained body temperature elevation owing to prolonged exposure to heat and humidity. We hypothesized that EIHS would cause kidney injury and cellular dysfunction. To test this hypothesis, female C57 mice were exposed to EIHS (n = 14; 37.6°C, 42.0% relative humidity) or thermoneutral (TN ...

Effects of rotor location, coning, and tilt on critical loads in large wind turbines [PDF]
Several large (1500 kW) horizontal rotor configurations were analyzed to determine the effects on dynamic loads of upwind downwind rotor locations, coned and radial blade positions, and tilted and horizontal rotor axis positions.

Upstream-radiated rotor–stator interaction noise in mean swirling flow [PDF]
, 2005 A major component of the noise in modern aeroengines is rotor–stator interaction noise generated when the wake from the rotating fan impinges on a stator row downstream.

Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis
International Journal of Chemical Kinetics, Volume 58, Issue 5, Page 199-209, May 2026.ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...

Technical Damage in Wind Rotor Blade under Static Load at Environment Conditions
Chemical Engineering Transactions, 2014 Accidents with a wind rotor blade are frequently observed in the wind farms and the simulation study of its undesired damage and its full degradation has to be done. As usual the full degradation of the wind rotor blade happens in a sequence of appearing
