Universal rotation speed source for aircraft engine

Abstract

The invention provides a universal rotation speed source for an aircraft engine. The universal rotation speed source comprises a brushless direct current motor, a speed increasing device, a rotation speed controller, a rotation speed measuring device, a transition connecting device and a rotation speed display device. The rotation speed controller is composed of a motor control driver, a photoelectric code disc speed measuring mechanism, an external speed setting device and a data setting device. The rotation speed controller is connected with the brushless direct current motor through a cable so as to control the rotation speed and the rotation direction of the brushless direct current motor. The brushless direct current motor is arranged on the main rotating shaft of the speed increasing device. The output shaft of the speed increasing device is driven by a belt wheel transmission mechanism, so that the transformation of the rotation speed is realized. The output shaft of the speed increasing device is connected with the rotation speed measuring device. The rotation speed measuring device is simultaneously connected with the rotation speed controller and the rotation speed display device through cables. On one hand, the actual rotation speed of the output shaft of the speed increasing device is fed back to the rotation speed controller, so that the rotation speed adjustment of the rotation speed controller is facilitated. On the other hand, the actual rotation speed of the output shaft of the speed increasing device is displayed in real time through the rotation speed display device.

Description

technical field [0001] The invention relates to a general rotational speed source suitable for aircraft engines, more specifically, relates to a general rotational speed source suitable for fixed-wing or rotary-wing aircraft engine rotational speed simulation. Background technique [0002] The engine tachometer and the rotor tachometer are important indicating instruments of the aircraft, which directly reflect whether the aircraft engine and the rotor speed system are working normally. Therefore, whether the tachometer can correctly and reliably indicate the corresponding speed is directly related to the flight safety of the aircraft and the completion of the mission. . [0003] At present, the current situation of testing the domestic aircraft speed system is that there is no corresponding speed test equipment due to the equipment of a new type of aircraft or the upcoming equipment of a new type of aircraft. Existing speed test equipment, some due to small power, single s...

AI Technical Summary

Problems solved by technology

Most of the existing speed test equipment is developed for specific models, which are highly targeted, not universal and comprehensive, and relatively poor in function expansion

Once there is a new type of aircraft or a new type of speed equipment is refitted, it is necessary to redevelop the corresponding test equipment, which wastes resources and affects the efficiency of support
