1. AIAA Paper 74-994, Rug. 1974.) greatly reduce accident rates. The NOTAH usi: much lower blowing than other circulation co!Itr.ul designs and operates at very low Reynolds numlr: so its research needs (Table 5) are unique. Tilt Rotor
2. Aprevious workshop on circulation c@ntml was hosted by the NASA Ames Research Center .,I 1982. Ovcrall, the attendel?i to the 1986 believe that significant progress has beer: but that adequate CFD codes for confident, dynamic design are not yet available for C flows. The impaptant unique aspects of circxi 3- tior control need further investigation, with coordinated experiments and theory development,
