The objective of the program was to design, fabricate, and perform acceptance tests on a flightworthy fluidic yaw damper system and to provide support during flight evaluation of the system. Control-system characteristics were optimized for the UH-1 series helicopters. This program incorporated ...
Based on Model Predictive Control (MPC) theory, the active yaw damper is designed, the objective function and constraint conditions are established, and the optimal damping coefficient is solved. The effect of the stability control of vehicle hunting motion is analyzed. The results show that ...
THE YAW DAMPER WAS SHUT OFF AND AN EMER WAS DECLARED AND A LNDG WAS MADE AT THE NEAREST SUITABLE ARPT WHICH WAS IND. DURING THE RECOVERY, THE ACFT WAS OBSERVED BY ARTCC WHEN IT WAS 700 FT BELOW THE ASSIGNED ALT AND THE CTLR ASKED THE PLTS TO SAY THEIR ALT WHEREUPON THE EMER WAS ...
Referring to FIG. 5, the clutch may be modeled as a spring-damper torsional element according to the following equation: TCT=c·Δω+∫k·Δω·dt (4) wherein c is the clutch damping coefficient, k is the clutch spring coefficient, and Δω=ωdiff−ωLwhich represents the diffe...
