Ground simulation and tunnel blockage for a swept, jet-flapped wing tested to very high lift coefficients

Ground effects experiments and large/small tunnel interference studies were carried out on a model with a 20 inch (50.8 cm) 25 degree swept wing. The wing is slatted, has a 60 degree knee-blown flap and can be fitted with unflapped tips. A tail rake of pitch-yaw probes can be fitted to the fuselage. Certain check tests were also made with a very similar straight-wing model

Cooked turkey roasts have different processing characteristics then cooked beef roasts

Roasts were manufactured from lean beef and turkey by injecting with brine to 25% above green weight so the raw product contained 1.8% salt and 0.3% sodium phosphate. Meat muscle characteristics (pH and protein solubility) and processing characteristics were measured as cook yields and expressible moisture. The species significantly affects some basic properties of the meat. Turkey meat had significantly higher pH and extractible myofibrillar proteins than beef. The increased cook yield was correlated with higher pH and higher expressible moisture. The differences observed suggest that processors need to treat the starting materials differently

Ground simulation and tunnel blockage for a jet-flapped, basic STOL model tested to very high lift coefficients

Ground effects experiments and large/small-tunnel interference studies were carried out on a model with a 20-inch (50.8 cm) span wing. The wing, which includes a highly deflected knee-blown flap can be fitted with unflapped tips and slats. A low-mounted tailplane can be fitted to the aft fuselage. Three-component balance meaurements, made with a fixed ground equipped with a single boundary-layer blowing slot, were compared with datum, moving-ground results. Good comparisons were obtained up to model blowing momentum coefficients of approximately two, after which the particular floor blowing settings used proved insufficient to prevent floor separation in the vicinity of the model. Skin friction measurements, taken routinely along the floor centerline, proved invaluable during the analysis of results, and their use is recommended as input to determination of floor BLC setting. A careful investigation was made of pitching moments, including tail-on, close-to-ground cases, with favorable results. Drag proved the most sensitive to the change from a moving to the boundary-layer controlled ground

Look at County Government

General criticism of the structure and form of local county government has been increasing. But studies show that most citizens haven\u27t much information about or much interest in their own county government. So there may be some merit in pausing to take a closer look at this uni
