Abstract:
To take into account certification modes in optimization problems of the nacelle of a bypass turbojet engine, we developed a method for numerical determination of the characteristics of the air intake in the engine operating regime with a crosswind. The flow and aerodynamic characteristics of the air intake in these regimes were studied. Experiments were carried out in a wind tunnel to validate the calculation method based on the solution of the Reynolds-averaged Navier–Stokes equations. The laminar-turbulent transition was simulated using the the Menter turbulence $\gamma$-model taking into account the compressibility of the gas.
