What cause AMC -14 to fail

Proton Failure Traced To Ruptured Gas Duct


[Satellite Today – 4-22-08] A rupture of the gas duct between the gas generator and the propellant pump turbine in the Breeze M main engine led to the March failure that left the AMC-14 satellite in a useless orbit, International Launch Services (ILS) said April 21.
The findings by the Russian State Commission investigating the failure said the most probable cause of the gas duct rupture was due to the combined effects of duct wall erosion, high temperatures and prolonged low frequency pressure fluctuation in the duct. Khrunichev, which manufactures both the Proton booster and the Breeze M upper stage, has been directed to perform corrective actions to fix the problems as well as improve the reliability of the Breeze M main engine before the vehicle can return to flight.
A Failure Review Oversight Board created by ILS also will review the findings then travel to Moscow at the end of this week for official briefings on the
findings and corrective actions. The board will determine if the corrective actions meet ILS standards for commercial return to flight.
“We and our partner, Khrunichev, are committed to a credible return to flight and an overall Proton recovery plan that restores customer confidence and future mission success,” Frank McKenna, president of ILS, said in a statement.

Why do I get the feeling this is what's going on over at Khrunichev:

Yeah, cause those 11+ million customers who don't have HD will be pissed if they don't add more HD!

It's all about growth, and most of the growth is in HD. Dish says so, Directv says so. Not to mention that the average revenue per subscriber is higher for people with HD.

Will Dish ever get any new Satellite up??

Will Dish be able to stay in business??

What does all the mean as far as getting new HD???

Will Dish ever get any new Satellite up??
Yup eventually.

Will Dish be ble to stay in business??
Didn't know E* was in financial trouble.

What does all the mean as far as geeting new HD???

Replacing E5 at 129W is a high priority for E*. E5 is almost out of fuel and has other problems. The new Ciel-2 will increase the capabilities at 129W with spots for HD LIL and CONUS TP's for national HD.

Waste Not, Want Not

Those 30 and 40 year old ICBMs after being disarmed are recycled into their "space" program.

When I read Duct Wall Erosion in the description of the problem...
