Sierra Nevada Reaches Major Engine Milestone for Dream Chaser

SIERRA NEVADA CORPORATION PRESS RELEASE

SNC fires hybrid rocket motor and begins production on Dream Chaser Vehicle

The Sierra Nevada Corporation (SNC) Space Systems Group announces the successful completion of two critical milestones for NASA’s Commercial Crew Development (CCDev) Program. On September 21, 2010, SNC completed three successful test firings of a single hybrid rocket motor in one day.  SNC’s newly opened rocket test facility in San Diego County, California, hosted NASA personnel for a rocket motor manufacturing review as well as the motor firings, including one firing under vacuum ignition conditions.  The tests, which simulated a complete nominal mission profile, demonstrated the multiple restart capability of SNC’s proprietary hybrid rocket motor.  This same hybrid rocket will be used as the main propulsion system on the Dream Chaser during the orbital operations.

[Editor’s Note: Sierra Nevada is the main contractor for Scaled Composites’ RocketMotorTwo, which will power SpaceShipTwo on suborbital flights. Both vehicles are using the same propulsion system. This probably explains why Scaled Composite and Virgin Galactic officials are predicting powered test flights of SpaceShipTwo in 2011.]

Sirangelo: Fund Dream Chaser for Orbital Flights, Let Orion Fly to the Moon

Sierra Nevada Corporation's Dream Chaser - a seven-person space shuttle designed for orbital flight.

The Denver Business Journal has an interview with Mark Sirangelo, head of Sierra Nevada Corporation’s space division and chairman of the Commercial Spaceflight Federation. He argues that NASA should fund Orion for deep space exploration only while robustly funding alternatives like the Dream Chaser vehicle that his company is developing for orbital flights.

Sierra Nevada Building On NASA Design
Aviation Week

The Colorado-based company is modeling Dream Chaser on the HL-20 lifting-body vehicle that NASA started as a potential International Space Station (ISS) crew rescue vehicle, which would have been able to transport a full station crew fleeing an emergency to a horizontal landing on runways anywhere in the world.

The $50 million in contract awards that NASA announced earlier this month will fund a number of approaches to commercial human spaceflight, including a new capsule and a small space shuttle. The space agency also spread out awards between newer, entrepreneurial companies and established aerospace giants.

SpaceX, Sierra Nevada Push Commercial Alternatives to Orbit

dreamchaser

The Houston Chronicle’s Eric Berger has an interesting Q&A with Mark Sirangelo, executive vice president of Sierra Nevada Corporation, and Larry Williams, vice president of strategic relations for SpaceX.

Berger: From the commercial perspective, how soon, and for how much money, could we have a low-Earth-orbit crew transport vehicle?

Sirangelo: Both of our companies are fairly well along in our programs to deliver crews to space. Our program uses a NASA-derived vehicle that has been in development by NASA for 10 years. We took it over four years ago, and are proposing to launch it on an existing launch system that has flown many hundreds of times. Our program is called Dream Chaser. We’re not looking to propose something that’s only on paper and hasn’t been discussed, it’s really about marrying two systems that have had significant amount of research into them. We think it can happen within a few years, not within a decade.
