In a supersonic aircraft, turbojet engine nacelles each containing two remote fans in the front half of the nacelle, for noise reduction at takeoff. During supersonic flight, a front wedge at the nacelle nose achieves external compression of intake air. The wedge is vertical, sending the airflow left and right inside the nacelle along its side walls. The two flows follow mirror image curved paths on their way to a turbojet, leaving unused space between them to house the fans in tandem. For takeoff, clutches connected to the turbojets's compressors are engaged. Driveshafts turn pinions against a gear on the same shaft as the remote fans. The fan output is discharged backward under the nacelle to produce thrust. The energy to turn the fans is taken from the turbojet cycle. The reduced exhaust jet velocity decreases its noise. Supercharging produces the extra power to turn the remote fans if multistage.
