Description

As a continuation of an investigation of the ejection release characteristics of an internally carried MB-1 rocket in the Convair F-106A airplane, fin modifications at additional Mach numbers and simulated altitudes have been studied in the 27- by 27-inch preflight jet of the Langley Pilotless Aircraft Research Station at Wallops Island, Va. The MB-1 rocket was ejected with fins open, fins closed, fins closed with a shroud around the fins, and fins folded with a "boattail" placed in between the fins. Dynamically scaled models (0.0^956 scale) were tested at simulated altitudes of 12,000, 18,850, and 27,500 feet at subsonic Mach ... continued below

Description

As a continuation of an investigation of the ejection release characteristics
of an internally carried MB-1 rocket in the Convair F-106A
airplane, fin modifications at additional Mach numbers and simulated
altitudes have been studied in the 27- by 27-inch preflight jet of the
Langley Pilotless Aircraft Research Station at Wallops Island, Va. The
MB-1 rocket was ejected with fins open, fins closed, fins closed with a
shroud around the fins, and fins folded with a "boattail" placed in
between the fins. Dynamically scaled models (0.0^956 scale) were tested
at simulated altitudes of 12,000, 18,850, and 27,500 feet at subsonic
Mach numbers and at 18,850, 27,500, and 40,000 feet for Mach numbers of
1-39, 1-59, and 1.98.
Successful ejections can be obtained for over 10 store diameters
from release point by the use of a shroud around the folded fins with
the proper ejection velocity and nose-down pitching moment at release.
In one case investigated it was found desirable to close off the front
one-third of the bomb bay. It appeared that the fins should be opened
after release and within 5 "to 6 rocket diameters if no modifications are
made on the rocket. An increase in fuselage angle of attack caused
higher nose-up pitch rates after release.

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
