| Abstract | A 12 inch diameter gear driven fan, having a gross disc loading of about 450 Ib/ft² , was installed in a wing for wind tunnel studies on the fan inlet.
The mechanical arrangements of the fan and drive, which included a turbine mounted at one end of the wing, are described.
Preliminary mechanical testing was carried out in the Engine Laboratory, after which the wing and fan were installed in a 10' x 20' wind tunnel for aerodynamic studies. Problems relating to oil seals and oil leakage are discussed.
About 20 hours of running were completed on the rotating machinery. A strip inspection of components then showed them to be in good condition. |
