35c were taken successively as the flow developed with time. " Such a vortex would cause even viscous-free flow to stagnate at point B. The resulting change in the pressure field is communicated upstream, which causes the retarded flow to come to a halt near point C. This situation is a typical point in a chain of events that causes the separation eddy to continuously advance upstream. DESIGN AND DEVELOPMENT a) Flow about a cylinder (from Prandtl-Tietjens). b) Smooth flow about an airfoil (from Prandtl).

When the i i )r i ! J Fig. 28 Arrangement of a turbofan engine. DESIGN AND DEVELOPMENT 49 50 AIRCRAFT PROPULSION SYSTEMS gas temperature is suddenly raised, the nozzle throat area must rapidly increase to pass the mass flow without an excessive pressure rise. The rate of change of the fuel flow must be accurately synchronized with the rate of change of the throat area. If the area increases too rapidly, thrust is momentarily lost just when an increase is demanded. If it is opened too slowly, the fan and possibly the compressor are pushed into surge.

To/T3) Losses in Engine Performance Chapter 3 of Ref. 2 presents an excellent discussion about keeping track of losses. The authors use increases in entropy as the natural quantity for evaluating various losses of available energy in turbines. This idea is equally true for the other components and for engines. We note first that Eq. 25b) The losses of Eq. 25a) are then expressed by = to AS The efficiencies of Eq. 3) are seen to be related to the sum of the entropy increases in the individual components.
