Frank N. Piasecki
Frank Nicolas Piasecki ( ; ; October 24, 1919 – February 11, 2008) was an American engineer and helicopter aviation pioneer. Piasecki pioneered tandem rotor helicopter designs and created the compound helicopter concept of vectored thrust using a ducted propeller. Early life and education Born in Philadelphia, Pennsylvania, to an immigrant Polish tailor, Piasecki worked for autogyro manufacturers while still attending Overbrook High School, then studied mechanical engineering at the University of Pennsylvania before graduating with a bachelor's degree from New York University. He was employed by the Platt-LePage Aircraft Company as a control engineer on their XR-1 twin-rotor project. In 1940, he formed PV Engineering Forum with former Pennsylvania classmate Harold Venzie. He built a single-person, single-rotor helicopter designated the PV-2 and flew it on April 11, 1943. This helicopter impressed the United States Navy sufficiently to win Piasecki a development contract. Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stroke
Stroke is a medical condition in which poor cerebral circulation, blood flow to a part of the brain causes cell death. There are two main types of stroke: brain ischemia, ischemic, due to lack of blood flow, and intracranial hemorrhage, hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of stroke may include an hemiplegia, inability to move or feel on one side of the body, receptive aphasia, problems understanding or expressive aphasia, speaking, dizziness, or homonymous hemianopsia, loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than 24 hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. subarachnoid hemorrhage, Hemorrhagic stroke may also be associated with a thunderclap headache, severe headache.

Piasecki X-49
The Piasecki X-49 "SpeedHawk" is an American four-bladed, twin-engined experimental high-speed compound helicopter developed by Piasecki Aircraft. The X-49A is based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and includes the addition of lifting wings. The concept of the experimental program was to apply the VTDP technology to a production military helicopter to determine any benefit gained through increases in performance or useful load. "SpeedHawk" is a concept aircraft based on applying X-49A compounding concepts to a production UH-60 Black Hawk offering better performance, range, and increases in useful load. The "SpeedHawk" aircraft includes an SPU (third engine), high forward-swept wing concept, a 45-inch "fuselage plug" cabin extension, and several other drag reducing and performance-oriented improvements, including a rotor hub fairing, landing gear streamlining, and a fly-by-wire flig ...
