Title: Requirements and Operations Team


1
Requirements and Operations Team
  • Industry Day Briefing
  • 17 January, 2002

2
Outline
  • Team Products
  • Requirements analysis and process
  • CONOPS development
  • Joint requirements matrix
  • Design reference missions
  • Comparison of AF and NASA requirements
  • Questions relevant to Requirements/Ops

3
Team Products
  • Mission Needs Document A document describing
    the high-level technical and mission needs of the
    developed system
  • Level I Requirements Document Quantify,
    compare, and combine, to the extent possible,
    traceable AF and NASA requirements
  • Concept of Operations Document A description of
    how the prototype system is to be operated
  • Design Reference Missions A technical
    description of the missions used as reference in
    the design of the system

4
Requirements Analysis
  • Analysis Addressed Five Key Questions
  • Question 1. What is the impact of an RLV system
    towards meeting present or projected NASA/AF
    requirements?
  • Question 2. If impact warrants an RLV system,
    when is it needed?
  • Question 3. What characteristics would an RLV
    system need to meet NASA/AF mission
    requirements?
  • Question 4. How do the characteristics of an AF
    system compare to those of a NASA system?
  • Question 5. What is the integrated set of
    requirements?

Sub-Mission areas
Questions 1 2
Identify Mission Attributes (e.g. responsiveness,
safety)
Review Past Studies
Determine Range in Characteristics Across
Sub-mission Areas
Question 3
Map attributes to requirements in each
sub-mission area
Review and Validate

CONOPS Development
  • Consolidates RLV prototype missions, operations,
    security, safety, and logistics
  • AF missions stressors
  • Force Applications Global Strike
  • Force Enhancement Responsive Tactical
    Intelligence, Surveillance, and Reconnaissance
    (ISR)
  • Space Control Space Superiority
  • Space Support Satellite Constellation
    Reconstitution. Refueling and Surge
  • NASA Missions
  • Alternate Access to International Space Station
  • Demonstrate technologies or objectives for
    follow-on systems
  • 2nd Draft complete - will evolve as required

Comparison of AF and NASA Requirements
  • Concurrence in many areas Reliability De-orbit
    mass Orbits Abort Scenarios
  • NASA and AF requirements do not currently
    converge in certain areas
  • Weight delivered to orbit
  • Payload 15 - 25 K lbs
  • Crewed 45 K lbs
  • Responsiveness AF lt 12 hours to 2 days NASA
    weeks
  • On-orbit capability Duration and
    maneuverability substantially higher for NASA
    (ISS driven)
  • Sortie Rate AF driven by future conflict
    scenario - could be high NASA low
  • Human rating AF no requirement NASA needed in
    FY12 system
  • Weather The AF has a requirement to operate in
    stronger winds, more precipitation and a wider
    range of temperatures.
  • Launch / Landing AF has a requirement to
    operate from inland CONUS AFB.

Questions For IndustryRequirements/Ops
  • What are the technology "long poles" to enable
    responsive space access (i.e., capable of
    achieving aircraft levels of cost, reliability
    and safety) over the next 25 years (Including
    vehicle, propulsion, ground infrastructure,
    operations, payloads, sensors, etc.)? Given your
    knowledge of currently funded NASA and Air Force
    programs, what would be your recommended
    technology roadmap? What changes and/or
    additional long-term technology investments
    should begin within the next seven years?
  • What RLV technologies does your company feel are
    state-of-the-art and ready for full-scale
    development today relative to your understanding
    of NASA and Air Force RLV requirements?
  • What is the earliest your company believes it is
    feasible to field a next generation RLV system(s)
    capable of meeting NASA and Air Force
    requirements? Please elaborate on your
    rationale and associated milestones. What would
    be the top 10 issues going into full-scale (or
    engineering and manufacturing) development of the
    next RLV (e.g., funding, technology maturity,
    immature requirements, joint program complexity,
    etc.)?

16
Questions For IndustryRequirements/Ops (contd)
  • What are the drivers for meeting operability
    needs? What is the value of early flight
    demonstrations using state-of-the-art systems
    (existing engines, TUFI TPS, SOA avionics,
    electric valve actuators, etc.) for demonstrating
    operability? What relationship (if any) exists
    between the size of the launch vehicle and
    operability? Describe/define observed
    interactions between safety and operability needs
  • Given your knowledge of NASA and Air Force
    requirements, what degree of commonality does
    your company believe is possible between NASA and
    Air Force RLV architectures and associated
    elements (including ground and flight systems)?
    Does your company see commonality between the
    NASA/AF needs and mission requirements and a
    commercial opportunity? Do you believe a modular
    RLV concept is possible whereby we support a near
    term demonstrator in the 15-25K payload class,
    and that booster in turn is a modular component
    of a larger RLV?
