This unit(SOU) supplies sealing oil to prevent mixing of hydraulic oil and liquefied methanol gas inside of FBIV(Fuel Booster Injection Valve) when the main engine operates. SOU is divided into large bore main engine(60 bore over) and small bore main engine(50 bore below) type by the number of membrane accumulator. The main components consist of an oil tank, an electric motor, a hydraulic gear pump, an oil filter, a control block, accumulators, and various senses, transmitters and indicators.

This Control Actuation System (CAS) is a guidance system for unmanned flying objects. It consists of three MPS fin actuators that each independently position an aerodynamic fin. The maximum angle of incidence is ±8°, which allows the device to carry out highly precise dynamic manoeuvres. The miniature fin actuators that make up this Control Actuation System are manufactured by MPS Microsystems and were designed based on customer specifications. Designed to guide a very small object and disposing of an extremely limited space, these fin actuators meet strict requirements in terms of performance, weight - less than 100 g - and dimensions. To reduce the length of this actuator, MPS Microsystems used part of the screw length as the motor axis. This screw is equipped with a very compact 4-point contact bearing that simultaneously absorbs axial and radial loads. The angular play on the aileron axis is less than 0.1° rms. This actuator meets the storage and vibration requirements of military equipment.

Features - Excellent absorption performance (Maximum: -25 dB, Average: -10 dB) - Frequency tuning capability available - Easily applicable to complex structures, including curved surfaces, gaps, and protrusions - Low dry density and specific gravity - Reduced number of coating layers, improving work efficiency - Passed environmental resistance and durability tests by the operational conditions of weapon systems - Electrical insulation properties to minimize the effects of lightning
