Joseph Smith was a Britishaircraftdesigner who took over as Chief Designer for Supermarine's upon the death of R. J. Mitchell and led the team responsible for the subsequent development of the Supermarine Spitfire. An aircraft is any machine capable of atmospheric flight. ... Designer is a broad term for a person who designs any of a variety of things. ... Supermarine was a British ship and aircraft manufacturer. ... Reginald Joseph Mitchell (20 May 1895-11 June 1937) was an aeronautical engineer, most notable for his design of the Supermarine Spitfire. ... The Supermarine Spitfire was a single seat fighter used by the RAF and many Allied countries in World War II. The Spitfires elliptical wings gave it a very distinctive look; their thin cross-section gave it speed; the brilliant design of Chief Designer R.J. Mitchell and his successors...
Subsequent flight tests of the aircraft with the discontinuity faired over indicated that the improved spin resistance provided by the modification had disappeared; this showed that the discontinuity was a key feature of the modification and also in agreement with the results of the model tests.
Aircraft models ranging from subscale to full scale were tested in both static and dynamic flight conditions in the Langley 20-Foot Vertical Spin Tunnel, the Langley 30- by 60-Foot (Full-Scale) Tunnel, the Langley 12-Foot Low-Speed Tunnel, and the Glenn L. Martin Tunnel at the University of Maryland.
Designed as a relatively short-coupled, high-aspect-ratio aircraft with emphasis on high cruise speeds, the Venture incorporated an NACA five-digit airfoil that was expected to have poor stalling characteristics.
Smith said the Urim and Thummim were from a prophet, Mormon, and revealed the record of ancient Israelites who had escaped to the Americas around 600 B.C. Smith, using the stones, translated the word of Mormon to form the new canon of The Church of Jesus Christ of Latter-day Saints, which was founded in 1830.
