Source information: apparently one of the six 1st stage engines went down in the first seconds of the flight.This is no Falcon 9....
AIUI, the 6 engines each gimbal in one plane only. Is the engine gimbal freedom tangential to the circumference or radial outward-inward?I wonder if a gimbal failure in one of them, a hard-over condition, is sufficient to overpower all the others' control authority? At around T+4 s there is a noticeable engine plume deflection to the "right" apparently in the engine nearest to the camera and the vehicle then starts sliding to the left and pitching clockwise as would be consistent with this TVC kick.
I was also thinking there had not been a Stage 1 failure early in flight since Soviet days.
For L2 members, here's a movie on the development of the Proton, and there's the video of almost exactly the same crash happening - except that it was in April 1969: http://forum.nasaspaceflight.com/index.php?topic=26935.0
Why no cut-engine command?
Quote from: ClaytonBirchenough on 07/02/2013 04:31 pmWhy no cut-engine command?Please read the thread before replying - this has been mentioned several times. before 45 seconds, the thrust termination is not active to prevent damage to the launch pad.
I'm used to Russian U/S failures but this is the first Proton core failure I've seen ever.
If I remember correctly, this is the first failure of Proton LV in many many years.
