This paragraph in Michael Stoiko's book made me sit up and take
notice:
=====
Of all LenGIRD's rocket designs perhaps the most unique was the LRD-D-
1, a rotary rocket engine conceived by A. N. Shtern in 1932. In the LRD-
D-1, the propellants were fed through lines running along the arms on
which the rocket engines were mounted. The engines' exhaust nozzles
were cut off obliquely so that the jet reaction force had a component in
the horizontal plane controlling the lever perpendicularly. Both lever and
engines were were attached to the bearing of the vertical shaft. This
formed a rotary system in which the propellant was fed to the engines
under the action of centrifugal forces. The rotating motors not only
suppplied propellants to the engines but also produced a gyroscopic
effect, ensuring stability in flight. The total weight of the rocket was 198
lb. This consisted of a 78-lb structure, 44-lb body assembly, 35-lb
engine, and approximately 40 lb of propellants. The thrust of the engine
was 440 lb, which gave the rocket an acceleration of 2g at liftoff.
