Description

Technical Field

Background

At present, a commonly used engine of a medium-and-large-sized investigation or inspection and beating integrated unmanned aerial vehicle is a turboprop aeroengine. Before the engine is formally assembled into the unmanned aerial vehicle, the ground test run of hundreds of hours is required to verify the mutual coordination condition of the fuel unit, the control system and the acquisition system of the engine, so as to obtain an accurate accelerator-rotating speed and accelerator-thrust torque curve. Current engine propeller tests are facing the following problems:

1. the risk coefficient of the test site is high, and the method is mainly characterized in two aspects:

because of signal transmission and engine starting control, operators often need to be close to a test site, a high-speed rotating propeller is extremely easy to damage a human body, and life cost is seriously required to be paid;

during the test run of the engine, exhaust gas is discharged through an exhaust pipe, wherein the exhaust gas contains harmful gases such as sulfur monoxide, sulfur dioxide, carbon monoxide and the like, and the exhaust gas stays near a test bed for a long time, so that the poisoning of the harmful gases is easy to cause, and the personal safety is endangered;

2. high-quality signal acquisition is difficult to realize, and along with the low-to-high rotation speed of the engine, the vibration frequency of the system covers the vibration interference from low frequency to high frequency, so that the high-quality signal acquisition and transmission requirements are higher;

Based on the above situation, a set of safe and reliable test system for the aeroengine mobile test bed must be provided, so that on one hand, personal safety of test personnel is ensured, and the test personnel does not need to approach to dangerous zones during the test, and on the other hand, the test result is more accurate and reliable, and the flight safety is indirectly ensured.
