Jet engine - Jet engine - Low-bypass turbofans and turbojets In the next higher regime of aircraft flight speed,the low supersonic range from Mach numbers above 1 up to 2 or 3,one finds the application of the simple turbojet (with no bypass stream) and the low-bypass turbofan engine (with a bypass ratio up to 2).Although the low-bypass turbofan (shown in Figure 6) has the same general Jet engine - Basic engine types BritannicaJet engine - Jet engine - Basic engine types Achieving a high propulsive efficiency for a jet engine is dependent on designing it so that the exiting jet velocity is not greatly in excess of the flight speed.At the same time,the amount of thrust generated is proportional to that very same velocity excess that must be minimized.This set of restrictive requirements has led to the evolution JMSE Free Full-Text Distributed Propulsion Systems for Aug 29,2020 Propulsor Types#0183;The aim of this study was to investigate the impact of distributed propulsion systems used on inland and coastal navigation in shallow water.Five layouts were assessed by computational fluid dynamics (CFD) simulation.The hull/propulsion layout cases have been analyzed for discrete flow speed values in the range 06 m/s.All cases have been examined under restricted draft conditions in
