The Rolls-Royce RB.37 Derwent is a 1940s British centrifugal compressor turbojet engine, the second Rolls-Royce jet engine to enter production. It was an improved version of the Rolls-Royce Welland , which itself was a renamed version of Frank Whittle 's Power Jets W.2B.
From 1985 onwards, all new machines carried the 'RB' name instead of 'Ruston-Bucyrus', and in 1987, a new mechanical/hydraulic powered 51–60 model developed from the 38-RB was offered for use as a crane or dragline excavator [1] In 1990, RB bought from its rival Priestman, the design and manufacturing rights to Priestman's Variable ...
The engine was a militarized version of the BAC 1-11 Spey, and called the RB.168-1. The Buccaneer S.2 served into the 1990s. The Buccaneer S.2 served into the 1990s. A Spey derivative, designed and developed jointly by Rolls-Royce and Allison for the LTV A-7 Corsair II , was produced under licence in the United States as the TF41 .
The Rolls-Royce RB.80 Conway was the first turbofan jet engine to enter service. Development started at Rolls-Royce in the 1940s, but the design was used only briefly, in the late 1950s and early 1960s, before other turbofan designs replaced it.
The RB.178 was cancelled in May 1966 and in June 1966 Rolls-Royce indicated it did not want to battle with P&W over the Boeing 747. In September 1966 Rolls-Royce revealed its decision to launch an Advanced Technology Engine (A.T.E) family covering thrusts ranging from 10,000lbf (RB.203) through to 60,000lbf. (RB.207).
Launched as the RB-211-524L in June 1988, [1] the prototype first ran in August 1990. [2] Its first variant is the Trent 700 introduced on the Airbus A330 in March 1995, then the Trent 800 for the Boeing 777 (1996), the Trent 500 for the A340 (2002), the Trent 900 for the A380 (2007), the Trent 1000 for the Boeing 787 (2011), the Trent XWB for ...
They are differentiated from later Gibson banjos by their scarcity. Banjo sales plummeted during the Great Depression, for lack of buyers, and metal parts became scarce into the 1940s as factories shifted to support the war. [1] As parts became scarce, non-standard versions came out, made from a variety of leftover parts, called floor sweep ...
Another obvious change was the replacement of the Wright J65 turbojets with Pratt & Whitney TF33-P-11 turbofan engines. The TF33s gave the aircraft more than double the thrust of the B model. The RB-57F was also fitted with two detachable Pratt & Whitney J60-P-9 turbojets mounted in pods attached to the wings outboard of the main engines. These ...
