The lift and thrust act in different directions for the forward phase of the flight whereas the lift and thrust act in the same direction for the other phases of flight, which is analyzed in this work. As most of the high-speed helicopters are using four-bladed main rotor configuration, it is analyzed with prior attention. Moreover, a specialized helicopter airfoil called HH02 is used in the Apache helicopter rotor for increasing the operational speed. The supercritical airfoil is used in the aircraft for attaining better transonic and high-speed flow characteristics. Email: Received: 01 September 2021 Accepted: 09 November 2021Ībstract: In this research, the aerodynamic performance and flow characteristics of NASA SC (2)-0714 airfoil and HH02 airfoil in the helicopter main rotor are evidently analyzed. ![]() ![]() Dhanya Prakash 2ġVisvesvaraya Technological University, Belagavi, Karnataka, 590018, India 2ACS College of Engineering, Bengaluru, Karnataka, 560074, India *Corresponding Author: Inamul Hasan.
