170 REPORTS ON INVESTIGATIONS AND PROJECTS. 



ENGINEERING. 



Durand, F. W., Leland Stanford Junior University, California' 



Grant No. 64. Experiments on ship resistance and propulsion. 



(For previous reports see Year Book No. 2, p. xxxii, and Year 



Book No. 3, p. 113.) $4,120. 



Abstract of Report. — Professor Durand has been occupied with a 



general review of the results of his work and the preparation of his 



final report. He expects to present a partial or abstract report in 



the form of a paper for the Society of Naval Architects and Marine 



Engineers at the annual meeting in November, 1905. The final report 



will be reduced to form for publication a few months later. 



Goss, W. F. Nl. t Purdue Universitj', Lafayette, Indiana. Grant No. 



114. Research on the determination of the value of high steam 



pressures in locomotive service. (For first report see Year Book 



No. 3, p. 114.) $5.ooo. 



Abstract of Report. — The original outline of this research provided 

 for a series of tests upon a modern locomotive designed to be oper- 

 ated under very high steam pressures. Since the report of Septem- 

 ber, 1904, all portions of the work have proceeded in accordance 

 with this outline, the tests contemplated having been run and good 

 progress attained in analyzing results. The tests have been made 

 in series, under pressures of 160, 180, 200, 220, and 240 pounds, 

 respectively. The results of each series represent different condi- 

 tions of speed and cut-off and serve as a complete definition of the 

 performance of the engine under the pressure of the series in ques- 

 tion. There have been made 71 complete boiler and engine tests 

 and 27 tests for which indicator cards only were obtained. In the 

 work of the year the experimental locomotive has been run the 

 equivalent of 1 r ,000 miles and has consumed 658 tons of coal. The 

 whole investigation has been accomplished in cooperation with the 

 authorities of Purdue University. 



In addition to courtesies acknowledged in a previous report, 

 material assistance has been rendered by the Lake Erie and Western 

 Railway Company in transporting to Indianapolis and return, with- 

 out charge, the experimental locomotive ; also, by C. Jutte & Co. 

 in furnishing coal, and by the American Locomotive Company. 



A vStatement showing the progress made and presenting some of 

 the facts developed appeared in the Railroad Gazette for June 9, 

 1905, under the title of " Locomotive performance under a steam 

 pressure of 25c pounds." The final presentation of methods and 

 results will soon be ready for publication.
