ABSTRACT:
An apparatus and method for modifying a jet engine to be carried externally in an inoperative condition on an aircraft to minimize aerodynamic drag and oscillation of the engine. The apparatus includes an annular inlet extension adapted to be mounted to the operating air inlet which slightly extends and contracts the inlet to reduce air spillage. The disclosed method includes the removal of the fan blades from the fan section of the inlet, attaching an ice deflector dome to the engine core inlet, and attaching the inlet extension to the nacelle air inlet.
