INDEX. TO TECHNICAL REPORTS.
The following is an index to 1,100 technical reports made by the engineering division of the supply group, Air
Service, at the experimental station, McCook.Field, Dayton, Ohio, from January, 1918, to December, 1919, inclusive:
This index is divided into two parts, as follows: r
Part I lists the reports numerically, according to the serial number assigned each report.
Part II lists the same reports (noted in Part I ) subdivided in accordance with the following grouping:
Airplane Department Memoranda (A. D. M. ).
Propeller Report (P . R. ).
Equipment Department Report (E. D.R.).
Power Plants Report (P. P. R.).
Full Flight Report (F. F . R .).
Armament Report (A. R. ).
Material Report (M. R .) .
Progress Report (Prog. R .).
Miscellaneous Reports (Misc. R. ).
Under these groups·no special scheme of listing the reports is followed, although for convenience the title of the
report is given first, then the serial number and date.
Heretofore, in addition to the serial number, a department number was given to each report. This department
number is not noted in this index, as the use of it has been discontinued.
NOTE.
The reports herein listed are in nature and content similar to those which are now is;ued separately as information
circulars. Duplicates of all reports are not available, and due to their bulk and the time required for reproduction
circulation will be limited to the most urgent requests. The confidential nature of many of the documents will also
prevent certain distribution to persons not in or directly connected 1vith the service.
