(Daniel and Florence Guggenheim Jet Propulsion Center, California Institute of Technology, Pasadena, Calif.)

A new method of power plant selection for vertical flight is proposed. It can be used to determine whether the performance of a rocket design can be improved by substituting for the rocket motor a different power plant such as a ramjet. Calculations indicate that there are advantages in using the ramjet provided the power plant can be made to operate under rapid acceleration and at high altitudes.

A problem constantly facing engineers who use jet propulsion ...
