flume 9 a small piece of equipment used for the visual study of 

 the flow oatterns around projectiles, was developed at the 

 same time as an accessory to the main tunnel , At a considerably 

 later date the design and construction of a controlled atmos- 

 phere launching tank and of a free-surface water tunnel were 

 undertaken Each of these pieces of equipment is described in 

 subsequent sections of this ,chapter 



This project was carried out under the direction of Dr, 

 R» To Knapp , Dr Vito A* Vanoni_, in his capacity of associate 

 directorj, shared the load of both technical and administrative 

 responsibility o Dr, James Wo Daily, as assistant director,, 

 aided in the general operation of the project and in particular 

 in the preparation of the reports Joseph Levy, He L» Doolittle ; 

 R. Mo Peabody, and G, E« Robisonj, were project managers who 

 supervised the individual tests and evaluated the results pre- 

 sented in detailed reports,, Ho B, Boiler and R c L c Page were 

 responsible for a large part; of the mechanical design of the 

 new instruments and equipment which were made necessary by the 

 demands of the work, Haskell Shapiro and Clarence Mo Edwards 

 played a similar part in the development of the rather com- 

 plicated electrical and electronic devices that were requiredo 

 Garrett Bo Van Pelt and Mrs Elizabeth Thorne were responsible 

 for the long series of flow studied made in the polarized light 

 flume o Robert Carr and Lee Holland were in charge of the 

 actual operation of the high-speed water tunnel and the makings 

 of all the test measurements, Hugh Stevens Bell and Miss Althea 

 Pease carried the responsibility of meeting the laboratory's 

 photographic needs g not only for the normal demands, but for 

 the development of carrying out the many specialized techniques 

 involved in using photography as a measuring tool. Wo Wo 

 Baustianj, Ho Thorne^, and Rudolph Lorman were in charge of the 

 construction and maintenance of the instruments and equipment 

 and the production of precision models that were required for 

 the work. There were numerous others who aided in the project. 



Shortly after the work on the high-speed water tunnel 

 had been started, a separate contract (OEMsr-329) was arranged 

 with California Institute of Technology for "studies and ex- 

 perimental investigations in connection with. the descent of 

 underwater projectiles when falling freely and when initially 

 propelled," Under Dr „ Max Mason as official investigator 9 

 a laboratory was set up at Morris Dam_, east of Pasedena, The 

 group there was concerned chiefly with tests of underwater 

 ordnance being developed or improved for service use, as 

 described later in this chapter.
