A convertible power tool that can operate in first and second configurations. The tool includes a base unit configured to receive at one time either a first module or a second module. The different modules provide for different levels of functionality. The first module includes one or more components that provide for a first level of functionality. The second module includes one or more components that provide for an advanced second level of functionality. Each of the base unit and first and second modules may include interfaces that provide for physical engagement as well as power/data engagement. In use, one of the first and second modules is connected to the base unit to provide for the desired functionality incorporated with the tool. The tool may also be reconfigured by removing the attached module and replacing it with the other module thus providing for a different functionality level.

An aircraft propulsor assembly includes a fan having a nacelle and plural fan blades radially disposed within the nacelle. The fan blades are configured to be rotated by torque generated by a turbine engine of an aircraft to generate thrust for propelling the aircraft. The assembly also includes an electric motor including a stator in the nacelle of the fan and a rotor in tips of two or more of the fan blades. The electric motor is configured to generate torque that also rotates the fan blades to generate thrust for propelling the aircraft. The assembly also includes a controller configured to reduce or prevent an increase in an operating temperature of the turbine engine of the aircraft by automatically supplanting at least some of the torque generated by the turbine engine with the torque generated by the electric motor.
