description: From Summary: "The effect on drag of positioning symmetrically
 mounted Douglas Aircraft Company, Inc. stores in pairs on a parabolic fuselage
 of fineness ratio 10.0 has been determined by flight tests of
 rocket-propelled, zero-lift models through a range of Mach number from 0.9 to
 1.8. The stores were mounted in half-submerged positions and on pylons and
 were tested in three longitudinal locations on the fuselage with the forward
 position being located at the maximum diameter of the fuselage. The effects on
 drag of removing the half-submerged stores or extending them outward on pylons
 also was investigated by tests of models with half-submerged-store cavities on
 the fuselage. Two pylons differing in airfoil section and thickness were
 tested at the forward position of the stores on the fuselage with cavities."
