The first free-flight stall test of the ARJ21 new regional jet aircraft model was a great success. Following this, the model completed several successful landings. This test marked an important milestone in the development of the ARJ21, as it aimed to study the stall characteristics and recovery procedures of the aircraft under controlled conditions.
During the test, the model was carried by a carrier to an altitude of 1,200 meters. Once released, it descended under its own weight, accelerating to the desired speed before leveling off. The entire flight was remotely controlled from a ground monitoring station, allowing operators to execute a series of pre-programmed maneuvers. At the same time, both ground-based telemetry systems and onboard test equipment collected critical data throughout the flight, providing valuable information for further analysis and research.
As the model reached a certain altitude, a parachute automatically deployed, ensuring a safe and controlled landing. This process demonstrated the effectiveness of the model's recovery system and confirmed the reliability of the overall testing setup.
The success of the first flight not only validated the performance of key systems such as remote control, telemetry, and onboard testing equipment but also laid a strong foundation for future free-flight tests. It also significantly contributed to the confidence surrounding the upcoming first flight of the full-scale ARJ21 aircraft early next year, ensuring a safer and more reliable path toward its operational debut.
