Background

• It will have capabilities to serve a variety of missions from docking at the international space station to expeditions beyond low Earth orbit.

• The Orion MPCV (multi-purpose crew vehicle is NASA’s latest spacecraft for human exploration.

• Orion will support four astronauts on missions up to six months long.

Department of Mechanical Engineering

Purpose

The purpose of this project will be to redesign the seatbacks for the medium-fidelity mockup(MFM), as well as, redesign the seatback for the flight model.

The medium-fidelity mockup is used for training the crew, testing hardware, and ensuring crewmembers can maneuver as needed. The medium-fidelity mockup is not built to the same high standards and quality that the flight model is.

The main focus will be to design the seatbacks for ease of manufacturing and lowering costs.

Department of Mechanical Engineering

Goals

Re-design the current flight model of seatback for cheaper manufacture

Improve stiffness of current headrest design Re-design current MFM Model of seatback Build 4 full-scale seatbacks for MFM Run required analysis of both Flight and MFM

models Meet specifications set by NASA

Department of Mechanical Engineering

Deliverables

Design and analysis results for flight model Design and analysis results for MFM Model 4 full-scale seatbacks with headrests for MFM Instruction/installation manual for MFM
