Completes Successful Integration Review for Space Station Resupply Mission

 SPARKS, Nev., May 25, 2017 – SPARKS, Nev. (May 25, 2017) – Sierra Nevada Corporation (SNC) successfully passed the third integration milestone for the Dream Chaser program under the NASA Commercial Resupply Services (CRS2) program, bringing it a major step closer to providing resupply services to the International Space Station (ISS).

CRS2 Integration Review #3 (IR3) confirmed SNC's Dream Chaser Cargo System design meets NASA's key requirements and maximizes probability of mission success during future flights.  The spacecraft is scheduled for at least six missions between 2019 and 2024. The reliability of the Dream Chaser design was also thoroughly reviewed as part of NASA's Phase I Safety Review Process, which successfully demonstrated safety and mission assurance criteria.   The reviews covered all stages of mission operations including ground, launch, flight and landing.

"Passing the third CRS2 integration milestone is a really big deal for the program and its future," said Steve Lindsey, vice president of Space Exploration Systems for SNC's Space Systems business area. "We are proud of this accomplishment and  are well on our way towards completing the next critical milestone and the remaining developmental phases.  It's a great feeling to be executing all our milestones on schedule and to be moving forward to our operational flight."

The spacecraft's unique cargo design transports more cargo mass (5,500 kilograms) to the ISS each mission.  In addition, a significant amount of cargo, almost 2,000 kilograms is directly returned fr om the ISS to a gentle runway landing at a pinpoint location. Dream Chaser's all non-toxic systems design allows personnel to simply walk up to the vehicle after landing, providing immediate access to time-critical science as soon as the wheels stop.

The complex and thorough review process found no significant design, build or system issues and underscored the Dream Chaser's readiness for flight.

The major elements of Milestone 3 included:
    [/li]
  • Successful completion of the NASA Phase 1 Safety Review
  • 32 Hazard Reports and 16 Safety Data Packages approved by NASA
  • Dream Chaser Architectural Design's met all CRS2 requirements (hardware, software, flight dynamics, thermal control, etc.)
  • More than 100 detailed design documents were delivered to NASA along with 30+ design reviews
  • During the three-day IR3 review, more than 1,000 charts were briefed to the approximate 45 member NASA and Federal Aviation Administration (FAA) team, which demonstrated that Dream Chaser is at Preliminary Design Review level of maturity
  • Launch vehicle operations, outside subcontracts and agreements
  • Range safety plan, as well as FAA, Federal Communications Commission (FCC) and National Telecommunications and Information Administration (NTIA) licensing
  • 5 Safety Review Phase 1 meetings were conducted prior to the IR3 review and involved the delivery of 46 individual Safety Data Packages developed under our S&MA team.
In addition to completing this milestone, the Dream Chaser atmospheric test vehicle is in preparations for flight testing that will help verify these designs. The spacecraft is currently testing at NASA's Armstrong Flight Research Center in California, having just successfully completed Phase One ground testing leading up to its second free flight test later this year.

Начало работ по Спирали лето 1966 г. Наш ответ Х-20 Dina-Soar(1963).
 Исследования по изучению возможности безопасного маневрирования и посадки на аппарате с низким аэродинамическим качеством после его возвращения из космоса проводились с июля 1966 по ноябрь 1975 года(Northrop HL-10 один из пяти).
Martin X-23 PRIME первый полёт декабрь 1966 г.

Но у нас то же подобное рисовалось и даже "продувалось" ещё с 1959 г.:

Закругляясь, хочу сказать, что Вы правы в том, что орбитальный самолёт Спирали был по сути вторичен.
Но вряд ли можно говорить о прямом копировании.

Кстати, наиболее точное описание дано, как это ни странно в википедии:
ЦитироватьThe historical antecedents of the Dream Chaser go back over 50 years in the U.S. with the 1957 X-20 Dyna-Soar concept and the 1966 Northrop M2-F2 and Martin X-23 PRIME lifting bodies.[11][12] Its design is derived from NASA's 1990 HL-20 lifting body design which was itself similar to the 1980s Soviet BOR-4, which in turn was considered by NASA engineers as influenced by the late 1960s HL-10,[13] and the Soviet Mikoyan-Gurevich MiG-105 military spaceplane concept,[14] a spaceplane studied as a means to develop a Soviet counterpart to the US's X-20 Dyna-Soar.

ЦитироватьSierra Nevada's Dream Chaser on the move in California
July 17, 2017 Stephen Clark
 
An atmospheric test model of Sierra Nevada's Dream Chaser spacecraft, a cargo carrier for the International Space Station that will take off on top of an Atlas 5 rocket and land on a runway, is undergoing braking and steering checks in California ahead of a flight test later this year, the company said Monday.

The full-scale Dream Chaser is pulled behind a tow vehicle for the ground tests now underway, reaching speeds fast enough to gauge the craft's braking performance and guidance, navigation and control systems.

Rolling on two main landing gear wheels and a nose skid, the Dream Chaser traveled down a runway Monday in Sierra Nevada's latest tow test at Edwards Air Force Base, which is co-located with NASA's Armstrong Flight Research Center.

Once cut free fr om its tow vehicle, the Dream Chaser slowed to a stop, allowing engineers to gather data on the craft's brakes, steering system, and guidance, navigation and control sensors that will line the spaceplane up for landing, according to Eric Cain, a Sierra Nevada engineer who described Monday's test on the company's Twitter account.

More tests are planned in the coming months, including additional tow tests and a "captive carry" flight with the Dream Chaser suspended under a helicopter.

"When that's done, we'll move into a series of flight tests, wh ere it will be dropped for approach and landing like the shuttle Enterprise," said Mark Sirangelo, corporate vice president of Sierra Nevada's space systems division, in an interview earlier this year.

Sirangelo was referring to the vehicle NASA used for landing demonstrations in the 1970s before the first full-up space shuttle mission.

The Dream Chaser will be dropped from heavy-duty carrier helicopter from an altitude of 10,200 feet (about 3,100 meters) above the ground for an autonomous landing at Runway 22L at Edwards Air Force Base.

The approach and landing test later this year will be the second time Sierra Nevada has dropped the Dream Chaser from a helicopter. A similar test using the same test vehicle in October 2013 made a smooth approach to the runway, but the Dream Chaser's left landing gear failed to deploy.

Sierra Nevada says the 2013 flight was successful until that point, and Dream Chaser's autopilot landing system steered the craft toward the runway for a touchdown on the centerline.

Engineers blamed the mishap on a landing gear borrowed from a U.S. Air Force F-5E jet. Future Dream Chaser cargo missions to the space station will fly with a different landing gear, and the refurbished spaceship now in California features a gear more advanced then the one at fault in 2013.

"It's much more close to the (configuration) of the orbital vehicle now, with flight software," Sirangelo told Spaceflight Now earlier this year. "It's fully autonomous, so it will use flight software that we'll go to orbit with. All the control surfaces, and all the data gathering is all electronic.

"The computer systems are now the orbital version of the computer systems that we will manage with, so it's structurally similar, but virtually the whole inside of the vehicle has been updated and changed."

Meanwhile, technicians are building the space-rated version of the Dream Chaser that will fly into orbit on a cargo run to the space station as soon as 2019.

The Dream Chaser is about one-quarter the length of NASA's space shuttle orbiters, and it will blast off from Cape Canaveral inside the payload fairing of United Launch Alliance Atlas 5 rockets.

It is capable of delivering more than 12,000 pounds (5,500 kilograms) of equipment to the space station inside its pressurized compartment and on an external aft-mounted payload carrier. At the end of each flight, the two parts will detach, with the Dream Chaser space plane returning to Earth with research specimens and other gear, and the disposable cargo module burning up in the atmosphere to incinerate trash.

Based on a lifting body aerodynamic design, the Dream Chaser will weigh about 20 tons fully loaded, likely requiring the lift capability of ULA's most powerful Atlas 5 configuration, the "551" with five strap-on solid rocket boosters, according to Sirangelo.

The ships returning from the space station will glide to landings at the three-mile-long Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, bringing back research specimens and other hardware. Sierra Nevada plans to reuse the Dream Chaser on multiple flights.

NASA sel ected Sierra Nevada's Dream Chaser in 2016 to join SpaceX's Dragon and Orbital ATK's Cygnus supply ships in the U.S. fleet of commercial space station cargo freighters.

SpaceX and Orbital ATK currently fly resupply missions to the space station under a contract due to expire at the end of 2018. Sierra Nevada will join the incumbent contractors under a follow-on agreement that runs from 2019 through 2024, during which each company is guaranteed at least six cargo flights.

Sierra Nevada initially developed the Dream Chaser to contend for a lucrative contract to ferry astronauts to and fr om the space station, but Boeing and SpaceX won that deal. Engineers redesigned the Dream Chaser for unpiloted logistics flights after losing the commercial crew competition in 2014.

The target date for Dream Chaser's first space voyage — Sierra Nevada and NASA agreed not to conduct a standalone orbital test flight — depends on when NASA authorizes the contractor to commence mission planning.

A NASA official said last month that the agency has, so far, only ordered one space station cargo mission under the new Commercial Resupply Services-2 contract. That order went to Orbital ATK for a resupply flight in 2019, but SpaceX and Sierra Nevada are expected to receive their first CRS-2 mission authorizations in the coming months.

Sierra Nevada has passed three "integration milestones" since the 2016 cargo contract award, in which NASA and the Federal Aviation Administration reviewed design documents and safety data packages.

Sierra Nevada finalized an agreement earlier this year for the Dream Chaser to dock or berth to the space station using an attachment mechanism developed by a consortium of European companies led by QinetiQ Space of Belgium.
