SR-N1
The Saunders-Roe SR.N1 (Saunders-Roe Nautical 1) was the first practical hovercraft. The concept has its origins in the work of British engineer and inventor Christopher Cockerell, who succeeded in convincing figures within the services and industry, including those within British manufacturer Saunders-Roe. Research was at one point supported by the Ministry of Defence; this was later provided by the National Research Development Corporation (NRDC), who had seen the potential posed by such a craft. In order to test the theories and overall concept, it was decided that a full-scale craft would be constructed, designated as the SR.N1. On 11 June 1959, it performed its first flight in front of the public. The SR.N1 participated in the test programme for four years prior to its retirement, by which point it had served its purpose in successfully validating the concept and further hovercraft had been developed. In less than four years following the SR.N1's maiden flight, multiple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SR N1 Class
The SECR N1 class was a type of 3-cylinder 2-6-0 ('mogul') steam locomotive designed by Richard Maunsell for mixed traffic duties, initially on the South Eastern and Chatham Railway (SECR), and later operated for the Southern Railway (SR). The N1 was a development of the basic principles established by the Great Western Railway's (GWR) Chief Mechanical Engineer (CME) George Jackson Churchward and by Maunsell's previous N class design.Scott-Morgan (2002), p. 18 The N1 prototype was the result of modifications made to N class No. 822 during construction in 1922. The locomotive became operational in 1923 and used parts interchangeable with other Maunsell locomotive classes. The prototype N1 was the only member of the class constructed before the SECR became part of the Southern Railway at the Grouping in 1923, and featured Holcroft conjugated valve gear, Holcroft's experience in this field later aided in the development of the Gresley conjugated valve gear which ...
