Patent number: 11939055Abstract: An aircraft can include a wing. The wing can include a tip. A winglet can be pivotably connected to the wing proximate the tip. A connecting member can be operatively connected to the wing and the winglet. The connecting member can include a flexible material with a super elastic material member operatively connected to the flexible material. Thus, the connecting member can allow passive movement of the winglet responsive to real-time operational forces acting upon the aircraft. In some arrangements, the flexible material can be a fabric, and the super elastic material member can be a wire. In some arrangements, the super elastic material member can be configured to exhibit a non-linear stiffness profile. The non-linear stiffness profile can include a region of quasi-zero stiffness. The stiffness profile of the super elastic material member can be selectively varied, such as by controlling a temperature of the super elastic material member.Type: GrantFiled: April 15, 2022Date of Patent: March 26, 2024Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Toyota Jidosha Kabushiki KaishaInventors: Rikin Gupta, Shardul Singh Panwar, Taewoo Nam, Ryohei Tsuruta, Yufei Zhu

Publication number: 20240060490Abstract: An electric pump system and method of operating the same involves pumping a fluid through a fluid passageway defined in a mechanical pump from a pump inlet to a hollow shaft of a motor, through the hollow shaft to an internal motor cavity defined by a housing of the motor, and through another fluid passageway defined in the motor housing and mechanical pump that leads to a pump outlet. The system and method further involve pumping the fluid through another fluid passageway defined in the mechanical pump from yet another pump inlet to the pump outlet. The temperature of fluid exiting the hollow shaft can be assessed and used by an electronic control unit (ECU) of the electric pump system to control the same.
