An analysis of the effects of lift/drag ratio and gross-thrust/ram-drag ratio on the benefits to be obtained from thrust deflection. It is shown that combinations of low values of these parameters can result in a substantial advantage. For example, at a lift/drag ratio of 4 and a gross-thrust/ram-drag ratio of 1.1, range may be increased about 34 percent. The required increases in altitude and engine capture area are also shown. 12 pp.

The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields.
