Scope & contents: Contains a price list for use of the MIT wind tunnel broken down by "Type of Experiment".

From page 2: "All the prices appended include the plotting of the customary curves and the furnishing of 2 sets of blueprints and a brief report. The prices given relate to tests which take their place in the ordinary order of work. Rush tests can be put through by overtime work at an increase in cost of from 25 to 100 per cent. The usual time for the completion of a test on a single wing or model is 10 days from the receipt of the model to the despatch of the report, but this time can not be guaranteed.

All tests will be run at a wind speed of 40 m. p. h. unless otherwise requested. The highest speed possible is 65 m. p. h. Models should be approximately 18 inches in span and should not in any case exceed 24 inches. Fuselages and airship forms may be from four to six inches in diameter. No model should weigh over four pounds, and the lighter the better. In constructing models the methods outlined in Report No. 74 of the National Advisory Committee for Aeronautics (Construction of Models for Wind Tunnel Test) should be followed. Models can be constructed at the Massachusetts Institute of Technology if desired, the average cost being $22.00 for a rectangular wing model of constant section and from $40.00 to $100.00 for a tapered wing."
