Exploratory flutter test in a cryogenic wind tunnel [PDF]

A model consisting of a rigid wing with an integral, flexible beam support that was cantilever mounted from the wall in the NASA LaRC 0.3-m transonic cryogenic tunnel was used in a flutter analysis study.

Morphology and function of pinniped necks: The long and short of it

The Anatomical Record, EarlyView.
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

Flutter of swept fan blades [PDF]

The effect of sweep on fan blade flutter is studied by applying the analytical methods developed for aeroelastic analysis of advance turboprops. Two methods are used.

Delivered cost of switchgrass pellets transported from depots to a biorefinery in the Piedmont, USA

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The southeast region of the USA has the potential to be a significant producer of biobased products; however, research is needed to demonstrate the most cost‐effective feedstock delivery system. This study considers a distributed network of five pellet depots to supply feedstock (i.e., switchgrass pellets) for the operation of a hypothetical ...

Application of Navier-Stokes analysis to stall flutter [PDF]

A solution procedure was developed to investigate the two-dimensional, one- or two-dimensional flutter characteristics of arbitrary airfoils. This procedure requires a simultaneous integration in time of the solid and fluid equations of motion. The fluid

The problem of propranolol poisoning

British Journal of Clinical Pharmacology, EarlyView.
Aims Propranolol is licensed in the UK and elsewhere to relieve symptoms of anxiety. In overdose, propranolol poisoning can be serious, difficult to treat and potentially fatal. This paper describes cases of intentional propranolol overdose reported to the UK National Poisons Information Service in order to raise awareness of the risk of harm following

Experimental transonic flutter characteristics of two 72 deg-sweep delta-wing models [PDF]

Transonic flutter boundaries are presented for two simple, 72 deg. sweep, low-aspect-ratio wing models. One model was an aspect-ratio 0.65 delta wing; the other model was an aspect-ratio 0.54 clipped-delta wing.
