Helicopter blade static/moving balance adjusting device

The present utility model belongs to the balance adjusting technology and relates to a static/moving balance adjusting device used for blades made of composite materials. The helicopter blade static/moving balance adjusting device comprises a front counterweight support, a rear counterweight support, a plurality of counterweight chambers, a front covering cap, a rear covering cap and a balance counterweight. The front counterweight support is close to the front edge of a blade, and the rear counterweight support is arranged on the middle position of the blade along the chordwise direction. The front counterweight support and the rear counterweight support are all provided with a plurality of counterweight chambers, wherein the counterweight chambers of the front counterweight support which are close to a blade tip are static balance counterweight chambers, the residual counterweight chambers are moving balance counterweight chambers, the counterweight chambers of the rear counterweight support are moving counterweight chambers, and the counterweight chambers are sealed by the front covering cap and the rear covering cap after balance counterweights are added into each counterweight chamber. By adopting the device, static balance and moving balance of a rotor wing system can be conveniently realized, flight safety can be enhanced, the overall structure is compact, the device can be repeatedly adjusted, and the practical value is large.
