NOTAR - The viable alternative to a tail rotor

An Aerodynamic Calculation Model for anti-torque system of NOTOR

“…10. Table 2 Contrast between calculation data and experimental data The variation tendency of lateral force coefficient Cy with momentum coefficient Cμ was same as experimental data [1]. With the increase of Cμ, the lateral force coefficient Cy increased gradually.…”

“…In order to validate the calculation model proposed in this paper, a three-dimensional model of anti-torque system was built according to [1], shown in Fig. 5.…”

“…The rest of air flow jets from thruster at the end of tail boom and produces the other part of lateral force. The aerodynamic analysis on anti-torque system is a difficult and topical point for NOTAR [1].…”

Assessment of CFD capability for prediction of the Coandă effect

“…An illustration of that design is given in Figure 3. The absence of a tail rotor permits a better safety and reduces the noise produced by the helicopter as discussed by Sampatacos et al [14], unfortunately this comes at the cost of an increased complexity.…”

Fundamentals and Applications of Modern Flow Control

“…This strategy has been utilized on the McDonnell Douglas NOTAR™ anti-torque system seen on the MD520N series of helicopters (Sampatacos et al, 1983). This strategy has been utilized on the McDonnell Douglas NOTAR™ anti-torque system seen on the MD520N series of helicopters (Sampatacos et al, 1983).…”
