STUDY OF AUTOMATIC CONTROL SYSTEMS FOR HELICOPTERS. PART 2. REAC STUDY OF RPM CONTROL FOR THE SINGLE-SPOOL TURBOPROP ENGINES

Abstract

The simulated single-rotor helicopter powered by a Continental Artouste I turboprop engine was restricted to vertical motion. The results of the REAC runs indicated that the outstanding differences between manual and a typical automatic rpm control are higher rpm deviation after a step gust input and a more rapid response of the helicopter following stick movements in manual control. From the standpoint of minimum complexity, the use of a control involving only proportional and integral feedbacks appeared most advisable, but to gain maximum tightness of control, rate should be added. The responsiveness of the helicopter varied only slightly from 1 optimum control to another, although it definitely degenerated when a considerable degree of temperature control was added. All of the rpm control configurations studied, except proportional alone or integral alone, exhibited worthwhile performance characteristics.
