Chamber:
Each chamber is 4 meters long, has four cycle motors with 4 efficiency radiators; the upper and lower nozzles' volume is controlled by separated inverters.
The chamber doors can be open from both sides, one side can be open manually, and another side can be open pneumatically to upside. The design is more convenient for machine checking and maintenance under different situation.
