The gyrodyne includes an inertial wheel mounted, via a wheel support, on the moving part or rotor of a cardan assembly. The cardan assembly is provided with a stator and the rotor is rotatable with respect to the stator about a first axis of rotation, it being possible for the spinner of the inertial wheel to be set in rotation about a second axis of rotation not aligned with the first axis of rotation. The stator of the cardan is mounted on a block and fixed to this block via an arrangement of vibration attenuators or insulators. The mechanism for setting the rotor in rotation is at least partially housed in the interior volume of the block.

Control moment gyro and device for assembly thereof

A control moment gyro comprising a wheel support structure which is mounted on a base by a motor, which is used to rotate the support around a first axis and bearing a wheel arrangement for driving the wheel spinner at a high speed around a second axis perpendicuIar to the first. The support structure includes a tubular part which rotates on the base and a flange which is disposed on only one side of the wheel and which is fixed both to the wheel and the tubular part. The diameter of the wheel and the point at which the wheel is fixed to the flange are proportioned such that the wheel penetrates the tubular part.
