Break down to push forward fuel modulator in the motor the mean quantity coefficient is obviously higher at the closeness status

After shooting about 50, the rocket airspeed attains a velocity, but pushes dint shortage to cause high error margin more big, spirit move to carry a lotus to exceed to design extreme limit, as a result can not fly as usual.
Break down to analyze committee exploitation to imitate flight, analysis data, check to etc. means to launch school quasi- experiment and get a conclusion:Break down to push forward fuel modulator in the motor the mean quantity coefficient is obviously higher at the closeness status.
The committee thinks that this may neglect in the production line to, check and acceptance experimented to wait a work preface and don,t discover this safety concealed suffer from.
The technical personnel denies that the blast-off failure relates to the low temperature motor of Russia production.The low temperature motor takes liquid hydrogen and liquid oxygen low temperature as fuel and combustion-supporting anticipate, compare with traditional motor to push dint larger, can deliver the satellite of larger quality.
