We have considered the orbital-free approximation of the kinetic energy functional to investigate the zero-temperature properties of dilute harmonically trapped two-component Fermi gas at unitarity. It is shown that our approach provides a realible and inexpensive method to study superfluid strongly interacting dilute Fermi gases.
