With test pilot Bruce Peterson at the controls, the M2-F2 suffered a pilot induced oscillation (PIO) as it neared the lake bed. At the core of this problem was the fact that the wings of the M2-F2 (essentially the body of the aircraft) produced considerably less roll authority than most aircraft.
The Soldier Hollow Classic held annually in Midway, Utah, United States is the most attended annual sheepdog championship in the world. This 2009 event drew 24,600 spectators. The most popular scoring system works as follows: [11] A judge watches each run and assigns a score based on their judgment. Each test element is assigned a maximum score.
The NASA M2-F1 is a lightweight, unpowered prototype aircraft, developed to flight-test the wingless lifting body concept. Its unusual appearance earned it the nickname "flying bathtub" and was designated the M2-F1, the M referring to "manned", and F referring to "flight" version.
The competitive dog sport in which herding dogs move animals around a field, fences, gates, or enclosures as directed by their handlers is called a sheepdog trial, herding test or stockdog trial depending on the area. [16] Such events are particularly associated with hill farming areas, where sheep range widely on largely unfenced land.
The HL-10 was flown 37 times during the lifting body research program and logged the highest altitude and fastest speed in the lifting body program. On February 18, 1970, Air Force test pilot Peter Hoag piloted the HL-10 to Mach 1.86 (1,228 mph or 1,976 km/h).
An Old English Sheepdog An Icelandic Sheepdog A Welsh Sheepdog A sheep dog or sheepdog is generally a dog or breed of dogs historically used in connection with the raising of sheep . These include livestock guardian dogs used to guard sheep and other livestock and herding dogs used to move, manage and control sheep and other livestock.
The test may be useful as a sensitive indicator of trauma induced by brain injury to laboratory rats. [7] Alcohol markedly impairs mouse performance in the rotarod test. [8] Research using the rotarod test with various chemical agonists and antagonists may help scientists determine which components of neurons mediate the effects of chemicals. [9]
Three-point hitches are composed of three movable arms. The two lower arms—the hitch lifting arms—are controlled by the hydraulic system, and provide lifting, lowering, and even tilting to the arms. The upper center arm—called the top link—is movable, but is usually not powered by the tractor's hydraulic system.
