Some fundamental aspects of a regeneratively cooled, upper stage rocket plane with external-burning thrust augmentation are investigated analytically. Cases considered are only the ejected coolant is burned externally and all of the thrust required for sustained cruise is provided by external burning. One conclusion is that external-burning configurations offer an apparent advantage over internal propulsion systems in that the total vehicle cooling requirement for high-speed operation is much less for the external- burning regeneratively cooled configuration. Also, the fuel required for propulsion by an external-burning configuration greatly exceeds the fuel required for cooling.
The static pressure distribution on sharp and blunt 10-deg half-angle cones was measured under rarefied conditions in both a uniform and a source flow field. Angle of attack of the cones was varied up to 10 deg. Pressure distributions are presented for cold-wall conditions at 18.0 = or
