Study on the Engagement Characteristics and Control Strategy of High Speed Difference Dry Friction Clutch

In the short/vertical take-off and landing aircraft propulsion system, vertical take-off/landing rapid flight are switched through engagement disconnection of dry friction clutch. The smooth connection clutch is crucial for mobility reliability this type aircraft. However, vibrates generates a large amount heat at high speed, which affects performance practice, when pressure rises quickly, time short, temperature rise small, but impact torque large, vice versa. view problem, with as research object, considering nonlinear variation coefficient lift fan load torque, dynamics model field speed difference established to analyze time, change. test shows that simulation results kinetic consistent results. To realize low rise, short variable slope control method proposed. Compared traditional fixed pressure, proposed can reduce simultaneously. provide reference short-range aircraft, development cost such improve design.
