DESCRIPTION
When constructing a DDG-51 Class Destroyer, Navy engineers regularly need to perform design reviews to verify and validate proposed ship changes. Currently, these design reviews are held using screenshots and model sharing of the ship's Computer Aided Design (CAD) models. However, 2D rendering of 3D spaces and objects can make it challenging to assess the actual layout and configuration of items. This can lead to errors in the ship design process, requiring costly rework later in the ship construction cycle.
The Navy seeks an innovative solution for VR software that allows Navy engineers to view the ship construction models as though they were standing in space. The proposed solution would allow the shipbuilder and the Navy to be better able to detect and correct errors early in the construction process. Additionally, such software could be used to train new engineers in the layout and navigation of the ship before they board it for the first time. There is currently no commercial technology that can meet this need.
The development of VR software faces several technical challenges. First, the shipyards use Computer Aided Three-Dimensional Interactive Application (CATIA) and Ship Constructor CAD models. The VR model must be capable of accurately using the outputs of both these CAD programs. The Navy understands this can be difficult and will require good knowledge of CAD file formats. Secondly, the user must be able to navigate virtual space and manipulate the environment. Many VR programs have some form of self-directed navigation. Destroyer spaces can have complex interior layouts and minimizing any motion sickness the user might experience while navigating VR can be a challenge. The solution should be able to load and view multiple CAD files, navigating between them with minimal lag and overlaying them to view discrepancies.
PHASE I
Develop a concept for a VR Model Walkthrough solution that meets the requirements listed in the Description. Demonstrate the feasibility of the concept in meeting Navy needs and establish that the concept can be developed into a useful product for the Navy. Feasibility will be established via a program demo or other means deemed appropriate. The Phase I Option, if exercised, will include the initial design specifications and capabilities description to build a prototype solution in Phase II.
PHASE II
Based on the results of Phase I, develop and deliver a prototype VR Model Walkthrough solution. The prototype software will be evaluated to determine capability in meeting the performance goals defined in the Phase II Statement of Work. Product performance will be demonstrated through multiple evaluations over the development cycle. An extended test by Navy personnel will be used to refine the prototype into a design that meets Navy requirements. Prepare a Phase III manufacturing and development plan to transition the Virtual Reality Model Walkthrough to Navy use.
PHASE III DUAL USE APPLICATIONS
Support the Navy in transitioning the technology to Navy use. Develop operations, maintenance, and technical manuals for the software to support the transition to the Navy.
There are many potential commercial applications for a VR Model to aid engineering design and training. Notable examples include commercial construction, commercial shipbuilding, architecture, and test and research reactors.
