    Abstract
  • For the current helicopter of single main rotor with tail rotor, the effect of inflow models with different characteristics on helicopter trim and digital simulation was discussed. Based on Pitt/Peters' first order dynamics nonuniform inflow model, the effect of uniform and nonuniform inflow models of main rotor on helicopter trim, and the effect of uniform and nonuniform dynamics inflow models of main rotor on helicopter dynamics response to pilot control input at different forward flight speed states, were analyzed, which could provide useful reference to chose the proper inflow model of main rotor for different flight digital simulation. The sample of UH-60A Black Hawk helicopter was used for the calculation and analysis.
