Project Plan
Arusha Rover Cockpit
1.0Project Objectives and Scope
1.1Project Objectives
1.1.1Determine the impact of driving visibility on the forward profile of the rover cockpit
1.1.2Create an architectural configuration for the cockpit interior
1.1.3Prepare cost estimates and identify vendor options for a medium fidelity mockup of the rover cockpit
1.1.4Engage at least five NSBE technical professionals and create STEM exposures for over 7000 youth in the pursuit of project technical objectives
1.2Scope Statement
1.2.1Arusha Rover
Swahili for "he makes fly (into the skies)", Project Arusha is a technology project to examine the transitional steps between early exploration and human colonization of the Moon. Arusha is based upon the concept of a central lunar outpost at the South Pole of the Moon that houses a population of 48 astronauts, with additional human-tended facilities scattered across the lunar surface. A long range rover is needed to provide crew transportation between the outpost and these facilities. The Arusha Rover project is a concept design for such a long range lunar rover, capable of circumnavigating the Moon in a 30-day period with a six-person crew. Multiple Arusha project teams will work together to complete this project.
1.2.2Arusha Rover Cockpit Team
The Arusha Rover Cockpit Team will create a point of departure design for the forward section interior of the Arusha Long Range Rover. Anticipated technical workis described in this plan and includesa cockpit windows visibility study and redesign, deployable crew wardroom table design, cockpit seat design, forward and side cockpit displays and controls design, and CAD models of the forward section interior. Additionally, the team will ensure the design is compatible with a future low fidelity cabin mockup assessment and develop a test plan for the assessment. The team will utilize the NSBE JEDI structure to conduct outreach and mentor NSBE students into STEM careers.
1.2.3Definition of Project Completion
Various Arusha Rover project teams will be created and disbanded over time as needed to perform subsets of the engineering work required to develop this vehicle. Ultimately, the Arusha Rover project will result in a prototype vehicle, in much the same fashion that NASA has developed the prototype Lunar Electric Rover that was field tested in Arizona as part of the NASA Desert RATS exercise. The Arusha Rover Cockpit project team is responsible for defining the interior of the forward section of the rover cabin. The Arusha Rover Cockpit project is defined as complete when the following work has occurred:
1.2.3.1A forward cockpit profile based on a driving visibility study has been submitted to the Arusha Rover Cabin Structures project team.
1.2.3.2A design has been completed for cockpit workstations, including a displays & controls layout.
1.2.3.3A design has been completed for cockpit crew systems, including placement within the cockpit.
1.2.3.4A design has been completed for the deployable dining and meeting table.
1.2.3.5A design has been completed for the crew seats, including seat adjustability.
1.2.3.6A design has been completed for cockpit stowage systems.
1.2.3.7A CAD model has been completed for all internal components of the Arusha Rover Cockpit and integrated with the Arusha Rover CAD model.
1.2.3.8A Master Equipment List has been completed for all internal components of the Arusha Rover Cockpit and integrated with the Arusha Rover MEL.
1.2.3.9A Requirements Compliance Review has been conducted by the Chief Technologist (or designee) to ensure that the CAD model and MEL represent a compliant design.
1.2.3.10Low or medium fidelity (as appropriate) mockups have been constructed to evaluate cockpit designs.
1.2.3.11Human-in-the-loop habitability and human factors evaluations have been conducted using cockpit mockups.
1.2.3.12Completed technical work has been presented as technical papers at a NSBE Aerospace Systems Conference or other aerospace industry technical conferences.
1.2.3.13A project close out review has been conducted by the Chief Technologist and Space SIG Director, including a go-no-go decision with regard to incorporation of project team work into a full scale medium fidelity Arusha rover cabin mockup.
The Arusha Rover Cockpit project team shall automatically disband upon completion of the project close out review.
1.3Scope Management Plan
The project team is based at NASAJohnsonSpaceCenter. The team, with support from the Space SIG Board of Directors and the Houston Space Chapter Executive Board will recruit appropriate African American subject matter experts from the JSC workforce to join NSBE and participate as members of the team. Work will be paced to align with the technical alignment of the project team. NSBE university chapters will be selected as JEDI Enclaves based on their ability to support key areas of project responsibility. Embry-RiddleAeronauticalUniversity will be the first such Enclave and a priority will be placed on completing the cockpit windows visibility study and redesign, with oversight of the Enclave as the primary duty of at least one Project Engineer. The Project Manager will allocate other portions of the cabin design to other Project Engineers as driven by team expertise and capability. The team will use its regularly scheduled meetings to track performance and resolve issues. Each Project Engineer responsible for an Enclave will also communicate at least weekly with that Enclave’s Padawan to ensure regular Enclave progress. Any changes in scope will be discussed with the Space SIG Director and Space SIG Chief Technologist, with modifications made to this Project Plan to accommodate them.
