Abstract: Embodiments refer generally to systems and methods for providing autorotative enhancement for helicopters (120) using an autorotative assist unit (110) coupled to the transmission (102) of the helicopter (120). Methods of utilizing an autorotative assist unit (110) as well as retrofitting an autorotative assist unit (110) to an existing helicopter (120) are also disclosed. By employing an autorotative assist unit (110), improved autorotation may be achieved without the need to increase the weight of the rotor (108).

Abstract: In some examples, an aircraft (600) comprises an airframe (602), a rotor system (604a, 604b) coupled to the airframe (602), and a vibration attenuation system (610). The rotor system (604a, 604b) is operable to exert a vibratory force on the airframe (602). The vibration attenuation system (610) comprises two or more batteries (606) and elastic devices (608). The two or more batteries (606) are operable to supply power to the rotor system (604a, 604b). The elastic devices (608) coupled to the two or more batteries (606) and the airframe (602). The elastic devices (608) are configured to attenuate the vibratory force based on facilitating oscillation of the two or more batteries (606). In other examples, a method comprises coupling elastic devices (608) to two or more batteries (606) and an airframe (602) of an aircraft (600). The elastic devices (608) receiving a vibratory force via the airframe (602) and attenuate the vibratory force based on facilitating oscillation of the two or more batteries (606).
