- Summary
-
Summary: A 1/10 size powered model of the Boeing XPBB-1 flying boat, which was dynamically similar to the full-size flying boat, was tested in Langley tank no. 1 to observe the effects of trim and powered propellers, of lengths of forebody and afterbody, and of various spray strips upon the low-speed spray characteristics. The effects of powering the propellers were to lower the trim and to pick up spray that would not strike the propeller disks when the propellers were windmilling. Lowering the trim increased the height of the spray with respect to the hull.
