TITLE: SMALL SPACECRAFT DIVISION FALCON 1E ADAPTER DEVELOPMENT PRELIMINARY DESIGN ANALYSIS 1.0 INTRODUCTION IN ORDER TO ACCOMPLISH PROGRAM AND PROJECT LEVEL ACTIVITIES, THE SMALL SPACECRAFT DIVISION HAS A REQUIREMENT FOR ADAPTER DEVELOPMENT ANALYSIS SUPPORT. THE MANDATE OF THE SMALL SPACECRAFT DIVISION INCLUDES THE DEVELOPMENT OF SMALL SPACECRAFT AND SUPPORTING TECHNOLOGIES NECESSARY TO ENABLE NASA SPACE EXPLORATION MISSIONS AND RESEARCH. THE FALCON 1E ADAPTER (HENCEFORTH THE ADAPTER ) DEVELOPED TO SUPPORT INEXPENSIVE RIDESHARE FOR UP TO 8 3U SIZE SPACECRAFT IS ONE OF A FAMILY OF ADAPTERS BEING DEVELOPED BY THE DIVISION BOTH INTERNALLY AND VIA SBIR RESEARCH FUNDING 2.0 SCOPE OF WORK THE TASKS REFERENCED IN THIS SOW ENCOMPASS ADAPTER DESIGN REVIEW, STRUCTURAL ANALYSIS, AND SUPPORT OF LAUNCH VEHICLE INTERFACE AND ENVIRONMENT REQUIREMENT COMPLIANCE. GOALS OF THE DIVISION ARE TO HAVE AN ENGINEERING MODEL OF THE ADAPTER FOR DISPLAY IN TIME FOR THE ANNUAL RIDESHARE WORKSHOP TO BE HOSTED BY NASA AMES IN THE LATE MAY TIMEFRAME. 3.0 DEFINITION OF TASKS TASK 1: BASED ON EXPERIENCE AND LESSONS LEARNED WITH THE FALCON 1 RIDESHARE ADAPTER, AND MUTUAL EXPERIENCE WITH NASA AMES ON INTEGRATION OF THEIR PAYLOADS ON THAT ADAPTER, DESIGN_NET ENGINEERING WILL PROVIDE SUPPORT FOR TECHNICAL INTERCHANGE MEETINGS WITH NASA AMES FOR THE PURPOSE OF PROVIDING DESIGN REVIEW, DESIGN ADVICE, AND ASSISTANCE WITH ALTERNATE STRUCTURAL APPROACHES FOR THE FALCON 1E CUBESAT ADAPTER . DESIGN_NET WILL ALSO EXAMINE STRUCTURAL COMPATIBILITY WITH LAUNCH VEHICLE REQUIREMENTS, AND REVIEW APPROACHES TO RELEASE (MECHANISMS AND ACTUATORS). TASK 2: PROVIDE PRELIMINARY (PRE-CDR) ANALYSIS SUPPORT FOR DEVELOPMENT OF THE NASA AMES FALCON 1E RIDESHARE ADAPTER. THIS WILL INCLUDE TRANSFER OF THE SOLID MODEL DEVELOPED FROM TASK ORDER 1 TO DESIGN_NET ENGINEERING AND OUR ANALYSIS PARTNER, INSTAR ENGINEERING. DESIGN_NET WILL PROVIDE A REPORT OF THE RESULTS OF THE PRELIMINARY ANALYSIS ALONG WITH SUGGESTIONS ON WHAT ALTERATIONS MAY BE REQUIRED TO MEET MARGIN REQUIREMENTS OR REQUIREMENTS ASSOCIATED WITH THE LAUNCH VEHICLE INTERFACE. 4.0 DELIVERABLES 4.1 REPORT RESULTING FROM EACH TECHNICAL INTERCHANGE MEETING (TIM) THAT PROVIDES RECOMMENDATIONS FOR STRUCTURAL AND MECHANISM DESIGN. 4.2 PRELIMINARY ANALYSIS REPORT ON THE STRUCTURAL INTEGRITY OF THE ADAPTER 5.0 TASK DEVELOPMENT APPROACH AND SCHEDULE 5.1 DEVELOPMENT THE ABOVE TASKS AND DELIVERABLES WILL BE CONSISTENT WITH THE NASA AMES GOALS OF DEVELOPMENT OF AN ENGINEERING UNIT ADAPTER FOR THE RIDESHARE WORKSHOP IN MAY 2009.
