How to choose thermodynamic cycle for designing new jet engine?
While designing new jet engine what parameters are important for choosing thermodynamic cycle?
what other parameters are important for jet engine designing?
low bypass ratio engine has low mas flow and high speed, high bypass ratio engine has high mass flow and low average speed.
if the high bypass ratio engine has high mass flow and high average speed, what are the advantages and disadvantages of this jet engine?
if you see bypass ratio varies from 0.1:1>br<1:1 for turbojet engine and 5:1>br<11:1 for turbofan engine.
Some turbofan engine has bypass ratio CFM 56 2c1 has 6, and CFM 56-5b3/4 has 5.3 and 5.5 has Ge 90 has 8.4 and ge 90-115b has 9 and various ratio. when your check this the thrust...
For Rocket,
Total Mass Flow rate W = F (Thrust) / Isp (Specific Impulse)
Fuel Mass Flow Rate Wf = W/(r+1)
Oxygen Mass Flow Rate Wo = W-Wf
r = fuel - oxygen mixture ratio
you have asked information about the inlet and outlet conditions or intermediate conditions...

how to find air mass flow rate in jet engine?
we are using thrust/Isp equation to find the mass flow rate for rocket equation. is that any formula available for finding the mass flow rate in jet engine
in turbojet and turbofan engine the hot gas exhaust velocity is less to compare with after burener turbojet and turbofan engine. in case the turbojet and turbofan enigne hot gas exhaust velocity is high without after burner, what is the advantage? assume it does not consume any additional fuel
hi
in jet engine power generated for two purpose
one is to drive the turbine, compressor and other accosseries
Second is for the forward jet thrust
take an example
A engine generates 15000 lb thrsut.
