RELATION OF TURBOJET PROPULSION SYSTEM DEVELOPMENT
TO THE STRATEGIC BOMBER MISSION*
By Addison M. Rothrock, Richard S. Cesaro, and Curtis L. Walker
A generalized analysis presents the effects of turbojet propulsion
system development and fuel selection on ability of a strategic bomber
to perform desired and minimum missions. The variation of bomber per-
formance using a hydrocarbon, boron, or nuclear fuel is discussed. With
chemical fuel, the effects of refueling are discussed. With nuclear fuel,
the nuclear cruise-chemical dash bomber and the nuclear subsonic tug tow-
ing a chemically powered supersonic bomber are compared. The factors
that determine bomber gross weight and bomber altitude are briefly
In planning the defenses of the country, it is desirable to examine
continually the technical likelihood of meeting operational requirements
set by the strategic bomber mission. A technical evaluation should pre-
sent the different methods by which these operational requirements can
be met, or, if they cannot be met, offer a comparison of the alternatives
that are currently technically possible. This report makes such an eval-
uation, and presents it in terms intended to be understandable to per-
sonnel not intimately familiar with the procedures of such analyses.
An examination is made of the interrelations between the basic var-
iables that determine bomber range, gross weight, and flight altitude.
Estimates are made of probable improvements that can be made in the pro-
pulsion factors, and of the resulting improvements in bomber range. To
a certain extent, the current discussion is a continuation of that pre-
sented in reference 1.
This analysis was made at the request of the U. S. Air Force and
has been presented orally to various USAF groups.
Here’s what’s next.
