The model is remotely controlled by the operator through the ground monitoring station for various predetermined actions. At the same time, the ground telemetry equipment and the test equipment within the model record various parameters of the model to provide data support for analytical research. After the model has dropped to a certain height, the parachute automatically opens the model and landed safely.
The success of the first flight not only verified the reliability of the various systems such as remote control, telemetry and test equipment, but also laid a solid foundation for the next free flight test of the model. At the same time, it provided a strong safety for the successful first flight of the ARJ21 new regional passenger aircraft early next year. Guarantee.
