Two years later, it moved its headquarters to Houston and in 1968 began the Cooper Rolls joint venture with Rolls-Royce to market gas turbines. The year 1987 marked the acquisition of Joy Industrial Compressor Group, founded in 1955 in Buffalo, New York, which was renamed Cooper Turbocompressor as part of Cooper Compression. W-K-M valves ...
Data from Rolls-Royce General characteristics Type: Twin-spool turboshaft/turboprop Length: 37.6 inches (96 cm) Diameter: 21.5 inches (55 cm) Dry weight: 201 pounds (91 kg) Components Compressor: Single-stage centrifugal Turbine: 2 stage GP, 2 stage PT Performance Maximum power output: 240–300 shaft horsepower (180–220 kW) Overall pressure ratio: 6.2 Power-to-weight ratio: 0.67 pounds per ...
Rolls-Royce based the 10-stage HP compressor on an 8-stage run in the RB401 in the mid 1970's followed by a 9-stage run in the RJ.500. The V.2500 would use 10 stages, with the first 4 with variable stators, giving a pressure ratio of 20:1. [4] A single-stage booster was also part of the original configuration.
The Clyde used a two-shaft design, with an axial compressor based on that of the Metrovick F.2 [4] [5] for the low-pressure section, and a single-sided centrifugal compressor scaled up from the Merlin 46 supercharger [6] as the high-pressure stage, both mounted on the HP shaft and driven by a single stage HP turbine. A single stage power ...
The Rolls-Royce AE 3007 (US military: F137) is a turbofan engine produced by Rolls-Royce North America, sharing a common core with the Rolls-Royce T406 (AE 1107) and AE 2100. The engine was originally developed by the Allison Engine Company , hence the "AE" in the model number.
The Rolls-Royce RB.183 Tay is a medium-bypass turbofan engine, developed from the RB.183 Mk 555 Spey core and using a fan scaled directly from the Rolls-Royce RB.211-535E4 to produce versions with a bypass ratio of 3.1:1 or greater. The IP compressor and LP turbine were designed using technology from the RB.211 programme. [1]
The Rolls-Royce BR700 is a family of turbofan engines for regional jets and corporate jets. It is manufactured in Dahlewitz, Germany, by Rolls-Royce Deutschland: this was initially a joint venture of BMW and Rolls-Royce plc established in 1990 to develop this engine. The BR710 first ran in 1995. [1]
The Rolls-Royce RB.41 Nene is a 1940s British centrifugal compressor turbojet engine. The Nene was a complete redesign, rather than a scaled-up Rolls-Royce Derwent , [ 1 ] with a design target of 5,000 lbf (22 kN), making it the most powerful engine of its era.
