Delta Systems Review Completed On CST-100 Design
The Delta System Definition Review (SDR) of Boeing's Crew Space
Transportation (CST)-100 space capsule design was completed May
19th, according to a company news relase Monday. The daylong review
included representatives from NASA, the FAA, and independent
consultants. They examined the changes made to the CST-100 design
since the initial SDR, which was conducted in October under the
original CCDev agreement.

"This review allowed the Boeing team to
incorporate changes in the design since the last review and to
update the overall baseline requirements," said Keith Reiley,
deputy program manager of Commercial Crew Programs for Boeing. "We
brought in outside experts, who reviewed the vehicle design from an
overall integrated system perspective to ensure that we are
designing and building a safe and affordable system."
Boeing engineers reviewed major spacecraft subsystems -- including
structures, thermal, electrical, propulsion, life support, software
and avionics -- as part of the Delta SDR, and reached agreement
during the review on a single integrated, consolidated baseline
design. The Boeing team also was able to show strong alignment
between the current design and NASA's draft Commercial Crew Program
Requirements.

The Delta SDR enables a common
understanding of the design baseline as the team progresses toward
a system-level Preliminary Design Review (PDR), which will further
mature the system design and ensure it meets all requirements.
Under the second round of NASA's Commercial Crew Development Space
Act Agreement, Boeing expects to complete its System PDR no later
than early spring 2012.
Boeing is preparing to gather performance data on the spacecraft's
launch abort system and service module fuel tank; evaluate vehicle
ascent performance in wind tunnel testing; and build on earlier
landing air bag and parachute demonstrations with more in-depth
investigations. With firm requirements and adequate funding, Boeing
plans to conduct test flights in 2014 and 2015 to support
operations beginning in 2015.
Boeing's Commercial Crew Transportation System (CCTS) includes the
CST-100 spacecraft, launch services and ground systems. The CST-100
is a reusable capsule-shaped spacecraft that has a crew module and
service module. The CST-100 relies on proven materials and
subsystem technologies and can transport up to seven people, or a
combination of people and cargo.

In addition to its support to NASA,
Boeing also plans to supply the CST-100 to Bigelow Aerospace for
that company’s inflatable space station. Boeing will also
work with Space Adventures to sell unused seats.
