 Blue arrow announces abnormal reason for pilot flight of Chu que No.1: propellant is exhausted in advance.


Yesterday evening, the blue arrow Aerospace announced the result of the investigation. Blue Arrow said the initial suspicion was due to the damage of a thrust chamber conveyor pipe in the final modification attitude control power system, resulting in decreased control force and propellant leakage, abnormal attitude control force, propellant depletion in advance. Following the summary of all the data, the final conclusion will be drawn from further analysis and the insurance claims will be prepared.

Blue Arrow said that during the whole flight, the Suzaku I maximum altitude 337 km, the fastest speed of 6300 meters per second. After 402 seconds of flight, the three level was abnormal, and the future number of the carrier failed to follow the scheduled plan.

After two days of analysis and interpretation of the data, the preliminary suspected cause is due to the last modified attitude control power system of a thrust chamber pipe damage, resulting in a decline in control force and propellant leakage, attitude control force abnormal, propellant depletion ahead of schedule.

It is reported that Blue Arrow Space has organized a number of experts to investigate, the follow-up summary of all the data, will further analyze the final conclusion, and proceed to prepare insurance claims. (quiet)

Attachment: Blue Arrow space Zhu que 1 flight test results preliminary interpretation of the full text

From October 27 to 28, 2018, Beijing Blue Arrow Space Technology Co., Ltd. (Blue Arrow Space) conducted a preliminary analysis of the rapid processing data of the flight test of the Zhuku-1 three-stage Solid Launch vehicle.

After data interpretation, the rocket ignition and takeoff are normal, the first flight is normal, the second flight is normal, the second flight is normal, the second and third separation is normal, the fairing separation is normal, the third glide flight is normal, and the rocket flight is normal after the third main engine ignition. The maximum flying height is 337km, the fastest speed is 6300m/s.

After about 37s (corresponding to the total flight time 402s), the main engine works normally, but the attitude control force is abnormal and the propellant is exhausted in advance. After preliminary analysis, it is suspected that the damage of a thrust chamber conveyor pipe in the final repair attitude control power system will lead to the decrease of control force and the leakage of propellant.

At the same time, many experts have been organized to carry out the survey, after the follow-up summary of all the data, further analysis will form the final conclusion.
