Icing has now become an important factor endangering flight safety. This paper takes the icing data of NACA 23012 airfoil as example, establishes influence model for real-time simulation based on time and aircraft angle attack, analyzes different geometry characteristics. The two-dimensional interpolation method is used to improve aircraft’s stall area, which mainly divided into correction lift...

This study presents a novel approach to parameterize the geometry of morphing trailing-edge flap that allows its aerodynamics be optimized while capturing expected structural behavior flap. is based on finite frame element method, whereby initial surface defined as structure with constraints are similar those passive skin. The shape modified by placing series distributed loads surface. method r...

The effects of N-acetylcysteine amide (NACA), a free radical scavenger, on cataract development were evaluated in Wistar rat pups. Cataract formation was induced in these animals with an intraperitoneal injection of a glutathione (GSH) synthesis inhibitor, l-buthionine-(S,R)-sulfoximine (BSO). To assess whether NACA has a significant impact on BSO-induced cataracts, the rats were divided into f...

Ionizing radiation is known to cause tissue damage in biological systems, mainly due to its ability to produce reactive oxygen species (ROS) in cells. Many thiol antioxidants have been used previously as radioprotectors, but their application has been limited by their toxicity. In this investigation, we have explored the possible radioprotective effects of a newly synthesized thiol antioxidant,...

The contributions of electrogenic sodium/calcium exchange current ( I NaCa), calcium-activated chloride conductance [ I Cl(Ca)], and calcium-activated nonselective cation conductance to delayed afterdepolarizations (DAD) were examined. Nonselective cation channels were absent in canine M cells, since inhibition of I NaCa and I Cl(Ca)eliminated all calcium-activated currents without abolishing c...
