This report describes work performed during the period from August 1, 1949 to November, 1950. When the project was started, it was financed for one year with the intention of continuing it for a second year, and the program
was planned accordingly. However, after about
three months of operation, it became necessary
for reasons of economy to reconsider the original
plans, with the result that the funds for the
first year's operation were reduced and plans
for continuing the work beyond the first year
were dropped. In the early summer of 1950,
the U. S. Air Force indicated its interest in
sponsoring the work. In view of this prospect,
the Office of Naval Research (ONR) allotted
funds for an additional three-months' period to
allow time for working out the necessary contractual
arrangements with the Air Force for
continuing the work. These arrangements were
worked out and the studies were continued under
contract with the Office of Air Research, starting
November 1, 1950
