Embodiment Construction
[0198] In order to facilitate the understanding of those skilled in the art, the following in conjunction with the embodiments and accompanying drawings to further illustrate the present invention, the content referred to in the embodiment is not a limitation of the present invention.
[0199] Reference Figure 1 As shown, a twin-engine helicopter avoidance zone curve calculation method of the present invention, the steps are as follows:
[0200] 1) Statistics on twin-engine helicopter parameters and engine parameters used;
[0201] Specifically, the twin-engine helicopter parameters in step 1) include: the total weight of the helicopter G, the rotational angular velocity of the rotor Ω, the number of propeller blades k, the rotor wing type (i.e., the rotor aerodynamic parameters are obtained, such as the rotor type resistance coefficient), the rotor radius R, the rotor solidity σ, the minimum rotational speed of the rotor after a single failure Ω min1 3. The minimum speed of the r...
