Alternative System for Hangar Bay Access Doors

Build and demonstrate a working proof of principle model for validation of the motor design process and verification of the proposed concept. The model will consist of a single sided motor stator, a slotted runner plate, and a cart capable of moving a hanging weight in the horizontal direction. The motor design will allow for the use of an existing motor drive (inverter) without the need for coil switches, and will demonstrate the fundamental operating principles of a single sided linear motor. The motor stator will be made up of a laminated iron core, and a three-phase copper winding, similar to most other linear motors and rotating machines. The moving component, or runner plate, will be made up of a laminated slotted iron core and copper bars, similar to the rotor and cage of a three phase induction motor (except laid out flat). The lower section of the door, capable of withstanding all required blast effects, will be proven utilizing a 3-D mechanical model. This effort is proposed in this solicitation.
