2009年12月,拜尔公司成功进行了两次凝胶演示器验证飞行。飞行结果证明,经过多年的深入研发,这种凝胶推进剂的所有性能达到了技术准备等级6级(TRL6)水平。尤其是凝胶添加系统和冲力调节装置在相应飞行阶段的表现达到预期水平。 In December 2009, Bayer successfully conducted two gel demonstrator validation flights. The results of the flight proved that after years of in-depth research and development, all the properties of this gel propellant have reached the level of Technical Preparation Level 6 (TRL 6). In particular, the performance of the gel addition system and the impulse adjustment device at the corresponding flight stages reached the expected level.
