The Bristol Siddeley BS100 was a two-spool, vectored thrust, turbofan, similar in general arrangement to that of the Pegasus, but with the addition of Plenum Chamber Burning (PCB), to enable the P1154 VSTOL fighter to accelerate to supersonic speed. Bristol Siddeley was a UK aero-engine manufacturer formed in 1959 from the merger of Bristol Aero Engines and Armstrong-Siddeley. ... Thrust vectoring is the ability of an aircraft to direct the thrust from its main engine(s) in a direction other than parallel to the aircrafts length. ... CFM56-3 turbofan, lower half, side view. ... Rolls-Royce Pegasus The Rolls Royce Pegasus is a turbofan engine manufactured by Rolls-Royce plc. ...

PCB is akin to reheat, but is only applied to the bypass stream, as the flow turns from fan exit to the nozzle bearing plane. Variable area front nozzles are required, to maintain consistent fan matching regardless of whether the PCB is alight or not. For other uses of afterburner, see Afterburner (disambiguation). ...

CFM56-3 turbofan, lower half, side view. ... Thrust is a reaction force described quantitatively by Newtons Second and Third Law. ... The compression ratio is a single number that can be used to predict the performance of any engine (such as an internal-combustion engine or a Stirling Engine). ... Specific fuel consumption, often shortened to SFC, is an engineering term that is used to describe the fuel efficiency of an engine design. ... Thrust-to-weight ratio (where weight means weight at the Earths surface) is a dimensionless parameter characteristic of rocket and jet engines, and of vehicles propelled by such engines (typically space launch vehicles and jet aircraft). ...
