Preliminary Detailed Design
Table of Contents
Team Vision for Preliminary Detailed Design PhaseThe goal for this stage was to make progress on selecting the final design. Some things we did during this phase:
- Consultations with outside advisers (Swagelock, RIT professors)
- Interface discussions with the test stand team (P19105)
- Concept selection based off of finalized engineering requirements
- Simulations and experiments to understand and perfect sub-systems
Prototyping, Engineering Analysis, Simulation
SimulationAt this point in time (11/19/2018) we still do not have access to NX, the desired program to be used for CAD and simulations. As a result, we have had to use alternate programs that do not have as desired simulation packages. The plan to mitigate this is to complete all of the CAD work within these programs, perform the best estimates we can, and then finish out simulations when NX licenses become available.
Experimental parameters are being generated to design quick and accurate experiments. The experiments will be done for the ignition system and injector system. For the ignition system, our goal is to ensure ignition 100% of the time in varying extremes of conditions (temperature, wind, gas flow rate). The injector experiments are to collect data in order to determine which of the two remaining designs will perform to the engineering requirements.
Input and Source
- Selected Concepts
- Feasibility Models
- System design and interface definitions
Bill of Material (BOM)Live BOM
(General Test Plans at this point)
- Test standards (e.g., ASTM). The RIT library maintains an infoguide with links to standards databases, many of which provide industry-standard test procedures for a variety of components and systems.
Outputs and Destination
- Report that summarized the degree to which Eng Reqs are satisfied.
- Assessment of accuracy of feasibility models.
- IRB Submission, if applicable (allow at least 30 days for this to be reviewed - more time is idea, since the IRB outcome may be a request for you to modify your proposed test protocol)
- Updated assessment from Subsystems Design. Have you driven the likelihood and/or severity down as you worked through the details of your design?
- Include a snapshot of your current risk assessment as well as a link to the live document.
