problems will be compared. The following servo drives will be considered:
a. Hydraulic systemsb. Fluid magnetic clutch systemsc. Electric motor systems
The following design criteria will be discussed in connection with the abovelisted servo systems:
a. Maximum acceleration and velocityb. Frequency response considerationsc. Minimum smooth tracking rated. Over-all system accuracy
AN AIRBORNE RADAR SCANNER WITH HYDRAULIC DRIVES

The important design features for an airborne radar with hydraulic drivesare discussed in detail. This includes such problems as: the gimballing of thescanner by means of a semi-circular scarf ring; cable drives, planetary gearreductions, and large angular freedom.
The pros and cons of hydraulic drives, the methods of accurate speed con-trol with hydraulic valves, and the reasons for high-speed, high-power servos arediscussed. Mention is made of the design tracking angular accuracies and servocontroller components that accomplish this.
