Résumé
In order to obtain design data for highly loaded ducted fans suitable for installation buried flat in the wing of a VTOL aircraft, it was decided to carry out a programme of experiments on 12-in. 0/D model fans. These were to be tested at true Mach number, and disc loadings of the order of 500 lb./ft? were to be sought, requiring a rotational speed of about 15,000 r.p.m. A test rig capable of driving these fans was built, and instrumentation to measure their performance developed for use with it. Most of the running carried out was without any forward-speed effect across .the fan inlet, but a later version of the rig was capable of simulating forward speeds up to 250 ft./sec. The rig and instrumentation are described, and the method of manufacturing fan blades is also outlined. The testing carried out on this rig is reported and analyzed in N.R.C. Aeronautical Report LR-367.
