AerodynamicsQuestion 1The continuity equation deals with the law of conservation of mass. The law of conservation of mass is illustrated by the continuity equation based on two aspects. First, the airflow can be stable or unstable. For unsteady flow, the second aspect of the equation relates to constant flow and is illustrated as follows: Applying this to an aircraft engine, an aircraft needs the correct amount of airflow in order to increase its thrust in flight. Since at cruise speed the engine thrust is only 17%, the plane must draw in more air to increase thrust. The continuity equation is therefore an important contribution to the flow of air into and out of the engine. The pressure must therefore be balanced at the compressor to allow an increase in intake at the intake. This would then be as stipulated by the continuity equation which illustrates that the rate of change of the mass flow rate at the inlet minus the mass flow rate at the outlet will give the rate of change of the mass storage. It is this storage mass which influences the increase in thrust. There is also a very large contribution of intake air flow to the aircraft pressure ratio. This means that since the effect of the engine on pressure is negligible, it is the air flow that affects the pressure ratio. For this reason, the amount of air drawn into the aircraft determines the pressure ratio as well as the thrust. It is therefore necessary to increase the air inlet in order to influence the storage change rate. For the aircraft to experience more air intake, several parameters must be changed. Indeed, the entry of air into an aircraft is influenced by flow distortion, turbulence... middle of paper ... principles related to gas laws and thermodynamic principles. For this reason, these aspects are very important since they illustrate the different changes in pressure, volume and temperature. A change in any one of the three elements results in a significant change in the others as well as in the energy generated during the entire time. Thermodynamic principles help explain differences in energy as well as the entropy generated from the initial internal energy of systems. Works cited by Charles Edward D and James E. Lewis.
