Multifunctional paddle moment ruler

Abstract

The invention relates to a multifunctional paddle moment ruler which comprises a clamp, a body, a dial, a horizontal indicator, an adjuster and a tension spring. The clamp is used for ensuring that the propeller blade is reliably clamped by the propeller moment ruler; the body is used for providing an installation space for the clamp, the adjuster, the dial, the horizontal indicator and the tension spring. The dial is used for marking the scales of the initial position and the final position of the level indicator; the horizontal indicator is used for indicating the variable quantity of the propeller pitch angle; the adjuster is used for adjusting the position of the horizontal indicator to ensure that the horizontal indicator is always horizontal; the tensioning spring is used for providing tensioning force for reliably clamping the propeller blade for the clamp. According to the invention, the functions of propeller pitch angle comparison and variable quantity measurement are realized by using the equipment.

Description

technical field [0001] The invention relates to a multifunctional propeller pitch ruler, which has a simple and compact structure, and has the functions of rapidly comparing propeller pitch angles and measuring changes. Background technique [0002] With the advancement of science and technology, more and more scientific research units and social organizations have rushed into the medium and large aircraft industry in recent years. As one of the core power components of the aircraft, the propeller provides powerful power for the aircraft. In the process of aircraft development, it is often necessary to check the specifications and pitch angle of the propeller, and to measure the variation range of the pitch angle. The current pitch angle measurement equipment uses an electronic level, which has the problems of poor anti-interference ability, limited resolution and complicated clamping. The invention has simple structure and reliable result. Contents of the invention [...
