201.~ Rotating or cyclic movement during axial thrust


DEFINITION

Classification: 60/201

(under subclass 200.1) Apparatus or process arranged so as to turn about an axis or having any kind of cyclic movement while producing a coaxial thrust component when in operation.

(1) Note. The motors included in this subclass are usually intended to turn or spin continuously about an axis at constant or variable rates in the nature of that necessary to obtain stabilization in flight or for other reasons. Motors having thrust direction modification means which momentarily causes the motor to rotate or turn about an axis, but which is not intended to impart continuous rotation is found below, for example, in subclasses 228+.

(2)

Note: Motors in this subclass may be provided with motive fluid ejecting means to produce rotation thereof. However, motors having means such as an air foil which causes the motor to rotate solely as a result of reaction with ambient air are classified elsewhere, as for example in Class 244, Aeronautics, subclass 3.23. See also Class 102, subclass 350 for pyrotechnic rockets having means to cause rotation of the rocket by gas discharge.
