(27) .\t the session of the North-East Coast Institution of 



Engineers and Shipbuilders for 1937-1938 there 

 was held a "Symposium on Propellers," at which 

 the following ten papers were presented. These 

 papers are published in NECI, 1937-1938, Vol. 

 LIV, pp. 237-414, with the discussions on pp. 

 D133-D222. The paper titles and authors are:

Behind a Ship"

Propeller Forms," NECI, 1937-1938, Vol. LIV, 

 pp. 321-326 and D185-D192. This paper covers 

 the tests of the 4-bladed narrow-tip A. 4.40 Wage- 

 ningen series, the B.4.40, and the B.4.55 series. 

 These had 15-deg rake and airfoil sections at all 

 radii.

 D41-D48. This second paper by Troost covers 

 the tests of 3-bladed propellers of the B.3.35 and 

 B.3.50 Wageningen series, also having 15-deg 

 rake and airfoil sections at all radii.

 normally based upon the model-test data of 

 D. W. Taylor. The circulation or vortex theory is 

 utilized to develop improvements not incorporated 

 in existing series. A mean camber line is selected 

 and the blade sections are superposed on it.
