ABSTRACT	This report describes the results of flow field measurement around the empennage of “ASKA”,which is the STOL experimental aircraft with an Upper Surface Blowing (USB) type powered lift device.As the downwash is closely related to lift,it becomes very large for STOL aircraft with high lift.Flow characteristics ng moment.The qh∞/q∞∽is greater than 1 in most cases,and it was found to increase with engine thrust.This system,using the pitot tube with vanes,is convenient for dounwash measurements.
