Design flaw cited in Korean rocket failure. The failed October debut of South Korea’s first regionally constructed rocket, the KSLV-2, is being blamed on improperly anchored helium tanks within the three-stage rocket’s higher level, SpaceNews reviews. The kerosene and liquid oxygen-fueled rocket launched its dummy payload into an unsustainable orbit when its upper-stage engine close down 46 seconds early. A failure investigation led via the Korea Aerospace Analysis Institute discovered that improperly designed constructions allowed helium tanks within the higher level to return unfastened right through flight, leading to a leak that disadvantaged the rocket’s engine of liquid oxygen.
Fortifying the anchors … The helium tanks with the inaccurate anchors had been within the higher level’s oxidizer tank, which used to be stuffed with liquid oxygen wanted for the rocket’s ignition. With the helium tanks coming unfastened, they disrupted pipelines throughout the oxidizer tank and led the liquid oxygen to leak, leading to early termination of the ignition. The problem shall be corrected via fortifying the helium tank anchors within the KSLV-2. A 2nd take a look at flight of the KSLV rocket will have to come later this yr. (submitted via Ken the Bin)
