The unit should include: еxecutive part, executing a control by the directing devices from basic control system on the commands of electronic block; reserve system, evecuting a control directing devices from a reserve regulator at the refuse of electronic block. The regulator should provide performance of following functions: control by direction devices on the commands of electronic block depending on polarity of input current into to the executive mechanism of regulator (РНА) (at the positive values of polarity of current operation rod must be pulled out, at negative - pulled in); control by direction devices on the commands of reserve regulator depending on the degree of increase of pressure of air in the compressor of engine. The aggregate (РНА) cooperates with the next objects of engine: by an electronic block; fuell regulator; by the servise line of pressure of air because of a high compressor (nonflow line); by the servise line of full pressure of air from engine input (nonflow line); by the mechanism of turn of shoulder-blades of directing devices. On the fifth stage of work the preliminary tests of pre-production models of aggregates of РНА42 (on 2th units of aggregate) are conducted with a resource 200 moto/clock. Adjustment of РКД, revision of pre-production models, is conducted on results tests.
