Electromagnetic Modeling of the Jet Aircraft Intake with the Interior Impeller
Abstract
The 3D electromagnetic model of the aircraft intake terminated with blade structure is based on the utilization of equivalence theorem and integral expressions for electromagnetic fields. Acceptable numerical efficiency is achieved due to implementation of the special algorithm of successive electromagnetic field calculation trough the sectioned air duct from inlet aperture to the termination section and backwards. The equivalent surface currents over the apertures separating the sections and conducting walls are calculated iteratively in separate processes for each section, wall smoothness and large dimensions of the duct are taken into account to reduce computational cost. Rigorous integral equation technique exploiting rotational periodicity of the impeller is employed to treat the termination. Far field is evaluated via integrating currents over the intake aperture. Computed data are close to reference results (including experimental ones).
