Abstract:

An experimental study was made to investigate some means to alleviate flow breakdown by using a number of different strake or fence configurations. A total of 23 different configurations were studied in the 4 x 6 ft. insert with a 2 ft. diameter rigid rotor at about 7 psf disk loading. None of the strake configurations studied in the experiment completely eliminate the effect of flow breakdown. A further experimental investigation is desirable because of the increasing interest in testing VSTOL vehicles in the transition speed range. Author
