Design a turbojet engine to flight at an altitude of 10000m. The pressure ratio across the compressor is 3. The turbojet inlet temperature is 1400k. The propulsion thrust must be around 32000N and the Mach number 0.8. Design based on your best knowledge the following components of the engine: a) Diffuser ans Nozzles. b) Compressor and Turbine. Determine the following parameters. a) The pressure and temperatures at each principal state in kPa and k. b) Air mass flow rate. c) The velocity at the nozzle exit. d) Power of the turbo-components. e) Fuel flow rate necessary to power the engine. f) Performance parameters (SFC, TSFC, etc.) Detail and combine your procedure, assumptions, and conservation laws with the best design practices of the turbomachine.
Bypass air exits at 600 m/s while combustion air exits at 1000 m/s. What is the thrust in kN of this engine?
Determine the required length L of each splice if a factor of safety is 2.75.
Refrigerant 134a leaves the evaporator as saturated vapor at 1.4bar and is heated at constant pressure to 20 degrees C before entering the compressor.
What is the discharge revised discharge pressure (guage pressure) of the compressor ? Is the assumption of change in temperature valid for calculating the discharge pressure of the compressor ?
If the engine exerts a traction force of 1/8 of the weight of the train, determine the speed of the train when it has traveled up the slope a distance of 1.1 . Neglect rolling resistance.
