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...
An inlet extension adapted to be fixedly mounted to the operating air inlet of a jet aircraft engine to be carried in an inoperative condition externally on an aircraft, said operating air inlet having a fixed hilite area, comprising: a removable annular inlet lip having a fixed hilite area less than the hilite area of the operating air inlet; and, means for attaching the inlet lip to the nacelle to reduce the hilite area of the engine while being carried in an inoperative condition.
