A Correlation of Two-dimensional Data on Lift Coefficient Available with Blowing-, Suction-, Slotted-, and Plain-flap High -lift Devices

Report presenting a correlation of the available data on various flap-type high-lift devices in two-dimensional form for flap-chord ratios ranging from 20 to 40 percent. Data for plain, single-slotted, and double-slotted flaps, and for suction and blowing flaps, are provided. Analysis regarding the effect of wing thickness and slot width is also provided for the various types of flaps.
