Guan Yi Communication Aircraft Company held the first "GA20 multicolor research test flying day event" in Hengdian Airport, Zhejiang Hengdian Airport, GA20 for the first time, stall test, stability test and manipulation performance test.
Research test flights are the necessary links developed by the aircraft model, obtain data through multi-expert research test flights to verify the safety, stability and handling of the aircraft. GA20 is also the first general aircraft model for the first process of demonstration to the public.
At 10:31 am, the crown is a second test flying member Daniel Muller boarding the GA20 aircraft, launched the engine, and slowly slide to the runway after the proficiency operation of a series of presupply tests. At 11 o'clock, the plane took off on time, followed by rapid climbing to 3,000 feet with 6m / s, the longitudinal stability, lateral stability, and stability of the longitudinal stability, lateral stability, and stability were performed at a speed of 140km / h and 180km / h.
Since then, after the plane climbs to 6000 feet, the tower command, and the GA20 performs a stall test. The so-called stall means that when the aircraft is a critical value, the wing is rapidly decreasing and cannot maintain normal flight, and is one of the important safety tests of the aircraft, which belongs to the high-risk factor. At 11:17, the test flyer adjusted the aircraft and reduced the speed. After that, the aircraft speed was reduced to 27m / s, and the atmospheric alarm started alarm; the pilot continued to reduce the speed to 24m / s, the wing fuselage began to jitter, the plane reached the stall, slightly Dow up, the pilot will immediately change the stall state and safely complete the stall test.
In the end, the aircraft returned to the land on 11:28, and the aircraft status was stable.
The implementation of this test flying task is the second test of the second test flywoman Daniel Muller. He served as a French Robin Aircraft Company's former designer, with more than 40 years of universal aircraft design and test flight experience, in 2018. Join the R & D and test flight team of Crown.
Daniel Muller said: "After a number of times and optimized, the stability of the aircraft increased significantly, this atmospheric test is more verified that the GA20 aircraft has reached the world's first-class model, with higher security, stability Sex and manipulation. "
Previously, the Chief of the Chief Tempered Director of SOCATA, the Crown of the National Flight School Junan Chicchle Christian Briand has completed engine parameters test, thermal ventilation system test, engine vapor chemical heating system test, and climb and take-off distance. Flight performance test.
Next, the crown will also complete the 200-300 frame test tasks in accordance with the Air Aviation Administration of China, complete the non-fuel flight test, and the weight of the center of gravity is expanded. The front-round swing test and other tests were tested and planned to obtain the Civil Aviation Authority (CAAC) model certificate before and after 2020 and launched an industrialization process.
GA20 aircraft from the project, design, trial to the first flight, last more than 3 years. This single-haired four fixed wing universal aircraft meets flight training, private flights, and tourism and other purposes.
The maximum battery life of the GA20 aircraft can reach 1200 kilometers, the cruise speed can reach 265 km / h, the climb reaches 5 meters per second, and the fuel consumption is only 32 liters per hour in the case of 2600 m height 75% power.
