Critical Design Review

Definition (see Project Description Document)

The CDR demonstrates that the maturity of the design is appropriate to support proceeding with full-scale fabrication, assembly, integration, and test. CDR determines that the technical effort is on track to complete the monorail and ground system development and mission operations, meeting mission performance requirements within the identified cost and schedule constraints.

• Establish the final configuration design, programming strategy and design, and operational characteristics through all the performance tests

• The final AEV design will be tested and results will be discussed

First-Year Engineering Program

Objectives

The following are typical objectives of a CDR:

Ensure that the "build-to" baseline contains detailed hardware and software specifications that can meet functional and performance requirements

Ensure that the production processes and controls are sufficient to proceed to the fabrication stage

Verify that the final design fulfills the specifications established at PDR and in the MCR

First-Year Engineering Program

Meeting the Objectives

Three Performance Tests, starting this week:

1. PT2 – Operational Objective/Energy Optimization

2. PT3 – Energy Optimization

3. PT4 – Final Testing

Performance Test 2 and 3 require a Test Readiness Review Document and Summary Report documenting experimental results, checked and graded, and filed within the Project Notebook

Project Management Review

Project Notebook• Maintain the Project Notebook

• Follow the Project Description Document

• Maintain good note-taking practices in documenting:• Brainstorming ideas• Notes on testing procedures, results, and observations

• Review graded marks and comments made for each graded Summary report for Performance Tests 2 and 3• Address comments and organize appropriately for PDR Report

• READ AHEAD• PLAN AHEAD
