Consolidated P-28
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with two Y1P-25 prototypes and YP-27, Y1P-28, and XP-33 proposals. The P-30 is significant for being the first fighter in United States Army Air Corps service to have retractable landing gear, an enclosed and heated cockpit for the pilot, and an exhaust-driven turbo-supercharger for altitude operation. Design and development In 1931, the Detroit Aircraft Corporation, parent company of the Lockheed Aircraft Company built a two-seat single-engined fighter aircraft based on the Lockheed Altair high-speed transport as a private venture. The prototype, the Detroit-Lockheed XP-900, flew in September 1931 and was purchased by the United States Army Air Corps as the Lockheed YP-24. Its performance was impressive, being faster than any fighter then in service with the Air Corps, and an order for five Y1P-24 fighters and four Y1A-9 attack aircraft was ...

Percival P
Percival (, also spelled Perceval, Parzival), alternatively called Peredur (), was one of King Arthur's legendary Knights of the Round Table. First mentioned by the French author Chrétien de Troyes in the tale ''Perceval, the Story of the Grail'', he is best known for being the original hero in the quest for the Grail, before being replaced in later English and French literature by Galahad. Etymology and origin The earliest reference to Perceval is in Chrétien de Troyes's first Arthurian romance ''Erec et Enide'', where, as "Percevaus li Galois" (Percevaus of Wales), he appears in a list of Arthur's knights; in another of Chrétien's romances, '' Cligés'', he is a "renowned vassal" who is defeated by the knight Cligés in a tournament. He then becomes the protagonist in Chrétien's final romance, ''Perceval, the Story of the Grail''. In the Welsh romance ''Peredur son of Efrawg'', the figure goes by the name Peredur. The name "Peredur" may derive from Welsh ''par'' (spea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphorus-28
Although phosphorus (15P) has 23 isotopes from 25P to 47P, only 31P is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are 33P with a half-life of 25.34 days and 32P with a half-life of 14.268 days. All others have half-lives of under 2.5 minutes, most under a second. The least stable is 25P with a half-life shorter than 30 nanoseconds.
