ЦитироватьВ США рассказали о двигателе VORTEX и программе OpFires для перспективных космических кораблей Dream Chaser
СМИ США сообщают, что корпорации Sierra Nevada удалось сделать существенный шаг вперёд в развитии программы создания нового ракетного двигателя. Его называют «гиперзвуковым».
Речь идёт о программе создания силовой установки VORTEX. Работа ведётся по заказу Агентства перспективных оборонных исследований и разработок США DARPA.
Компания расширяет возможности двигателя VORTEX за счёт использования новой программы OpFires.
Из материала Defence Blog:
Цитировать"С помощью OpFires компания Sierra Nevada расширяет возможности своего гибридного двигателя VORTEX. В системе используется высококачественное твёрдое топливо с жидким окислителем, и эти составляющие одинаково стабильны как на Земле, так и в космосе. Недавнее тестирование показало положительные результаты".
Отмечается, что система обладает высокой мощностью при учёте своей компактности. При этом никаких детальных параметров не озвучивается.
Утверждается, что двигатель получил возможность глубокого регулирования и плавного перезапуска по команде.
Вице-президент Sierra Nevada Том Крэбб отмечает, что обновлённая программа открывает для компании рынок не только в военной сфере, но и в гражданской – космической.
ЦитироватьТом Крэбб: "Возможности силовой установки по управляемости и перезапуску расширяют спектр возможных траекторий полёта различных систем".
На данный момент проведено около 30 испытаний.
В компании заявляют, что новая силовая установка станет основой для перспективного многоразового космического корабля «Dream Chaser». Это грузовой корабль, который (по плану) должен доставлять на низкую опорную орбиту до 5,5 тонн грузов и забирать с орбиты до 1,85 т. Объявленная стартовая масса составляет 11340 кг. В США разрабатывается как беспилотная, так и его пилотируемая его версии, пишет "Военное обозрение".

The wings were made in Fort Worth, TX by @LockheedMartin. They're made out of the same carbon composite material and processes that were used to make the primary structure for our Dream Chaser® spaceplane.




1:50 AM - Apr 22, 2020

Each wing for the Dream Chaser® spaceplane is more than 13 feet long and the vehicle is 30 feet long!




2:50 AM - Apr 22, 2020

Dream Chaser® spaceplane gets its color from black & white Thermal Protection System tiles. It doesn't have that color now, but when complete, each Dream Chaser wing will feature more than 150 of those tiles!

ЦитироватьDREAM CHASER® SPACEPLANE MILESTONE: WINGS ARRIVE
April 21, 2020



Today, we're celebrating a big milestone in the Dream Chaser program: its wings have arrived! The wings recently arrived at the Louisville, Colorado facilities.

So what should we know about the wings – and why is this such a big milestone? We spoke with Sierra Nevada Corporation's Wing Structural Design Lead, Trent H. to learn more.

How are the wings for Dream Chaser different fr om those you'd see on an airplane?
There are multiple differences:
[LIST=1]
[/li][li]The wings for Dream Chaser must survive in space like a satellite and be operational in atmosphere like an aircraft. This presents an interesting design challenge with tremendous temperature extremes.
[/li][li]Dream Chaser features a lifting body airframe. This means the body creates lift similar to that generated by the wings of a conventional aircraft. Because of this, the wings for Dream Chaser have a steep angle to enhance the stability of the vehicle while also adding to the lift generated by the body of the spacecraft.
[/li][li]Just like the body of Dream Chaser, the wings are both a single composite structure. This innovative technology saves weight without compromising strength and stiffness.
[/li][/LIST]
Tell us more about what the wings are made of.
The wing structure is made of carbon fiber and attached to the body using titanium components. It's the same material that's used for the primary structure for Dream Chaser.

The wings will have a layer of tiles on the outside - what benefits does this provide?
The tiles give Dream Chaser its black and white color, but most importantly act as a thermal shield, protecting it from the extreme temperatures the space vehicle will face both on-orbit, and during re-entry.

We started with the tile technology from the space shuttle program, but advanced the product, developing a more lightweight tile that is capable of withstanding equal or greater temperate variations.

These tiles are also stronger than those used on the space shuttle, which will help protect Dream Chaser from micro-meteorite debris.

When complete, each wing will be more than 13 feet long, and will have more than 150 tiles on it.

Are Dream Chaser's wings stationary?
No.  The wings will be stowed while Dream Chaser is in the fairing. That's wh ere Dream Chaser is stored both before and during launch.

After the launch vehicle separates, the complex Wing Deployment System deploys the wings using components that will ultimately lock the wing in place while the space vehicle is on-orbit. Once deployed, the wings will remain in that configuration until after landing.

Why was this such an interesting design challenge for you?
The Dream Chaser mission in itself presents a unique set of requirements. When you add in the fact that the primary structure is pushing the boundaries of composite assembly, the resulting design challenge is a once in a lifetime opportunity.

What does working on the Dream Chaser team mean to you?
The Dream Chaser team is an awesome group filled with some of the smartest people I've ever met. I'm proud to work alongside such a talented and friendly team of people determined to meet the end goal.

ЦитироватьSNC'S "DREAM CHASER TENACITY": FIRST ORBITAL VEHICLE OF DREAM CHASER® SPACEPLANE FLEET REFLECTS NATIONAL MOOD

On National Space Day, Private Space Contractor Honors Core Value and National Spirit

SPARKS, Nev., May 01, 2020 – Sierra Nevada Corporation (SNC), the global aerospace and national security leader owned by Eren and Fatih Ozmen, marked National Space Day by announcing the name of its first orbital vehicle set to launch under contract with NASA: Dream Chaser Tenacity.

"Tenacity is in SNC's DNA," said SNC Chairwoman and President Eren Ozmen.

"Every critical moment in SNC's history of innovation has called for tenacity, in overcoming challenges in order to support and protect explorers and heroes. As the nation faces this current challenge, we want this vehicle to be a beacon of hope that American ingenuity – and tenacity – will bring brighter days ahead."

SNC's Dream Chaser spacecraft, known as "America's Spaceplane™," is the world's only non-capsule, commercial spacecraft and is capable of a runway landing. Under a NASA contract, it will perform cargo delivery and disposal services to and from the International Space Station on at least six NASA missions.

"Dream Chaser is a story of grit and tenacity on the part of SNC's team," said John Curry, SNC's Program Director for Dream Chaser. "NASA's vision and ours for a next gen space shuttle with a gentle runway landing has weathered tough economic and budget resources and competing visions. The team and engineers working on Dream Chaser have believed in its superior design, knowing tenacity would lead to Dream Chaser flying in space and returning humans and science back to Earth safely."

NASA this week selected the Dynetics team, of which SNC is an integral part, to support its Artemis mission to the moon. SNC is leading development of the crew module for NASA's Human Landing System (HLS) program, which will ferry astronauts and supplies to and from the moon's surface. The program is designed to provide new science and material resources and leverage the moon as a proving ground for future Mars missions. NASA's goal is to land astronauts on the moon by 2024 and establish sustainable missions by 2028.

About Dream Chaser Spaceplane & Shooting Star Cargo Module
Owned and operated by SNC, the Dream Chaser spaceplane is a reusable, multi-mission space utility vehicle. It is capable of transportation services to and from low-Earth orbit and is the only commercial, lifting-body vehicle capable of a runway landing. The Dream Chaser Cargo System was selected by

NASA to provide cargo delivery and disposal services to the International Space Station under the Commercial Resupply Services 2 (CRS-2) contract. All Dream Chaser CRS-2 cargo missions are planned to land at Kennedy Space Center's Shuttle Landing Facility.  The Shooting Star cargo module is a 15-foot attachment to Dream Chaser that provide extra storage for payloads, flexible mission options and facilitates cargo disposal upon re-entry into Earth's atmosphere.

А давно они решили, что крылья раскладываться будут? Не удержались, пришли к тому же решению, что и у Боров?

Была пилотируемая версия запускаемая без обтекателя - проиграли контракт из-за сложности проекта (да и выйгрывшие контракт не справились в срок). Чтобы больше доставлять в грузовом контракте за один раз придумали "багажник" и спрятали все в обтекатель.
Бор кажется имел регулируемый угол раскрытия, интересно, а этот?

И до Боров были с изменяемым положением крыла, минимум в кино, в теме был пример.

ЦитироватьSNC'S DREAM CHASER® SPACEPLANE'S SHOOTING STAR ARRIVES IN COLORADO FOR INTEGRATION
Transport Vehicle Passed Critical Testing on Accelerated Timeline

SPARKS, Nev., May 14, 2020 – Sierra Nevada Corporation (SNC), the global aerospace and national security leader owned by Eren and Fatih Ozmen, received its Shooting Star transport vehicle at the company's Colorado production facility, marking the beginning of a key integration phase. This phase includes installation of the SNC-built Passive Common Berthing Mechanism that will allow SNC's Dream Chaser Tenacity spaceplane, the first orbital vehicle in the company's Dream Chaser fleet, to berth to the International Space Station.

Shooting Star is a 16-foot tall attachment to Dream Chaser that has capacity for more than 10,000 pounds of additional payloads to the International Space Station. It represents the first composite pressure vessel ever test-verified for visiting the International Space Station.

"This is a landmark milestone, not only for SNC, but for all of space exploration," said SNC owner and CEO, Fatih Ozmen. "This state-of-the-art, mission-ready structure is a testament to SNC's ability to deliver more capabilities to our customer without compromising on design."

Built primarily fr om advanced composite materials, Shooting Star has a high strength-to-weight ratio, allowing it to achieve a high payload capacity to the space station. The structure was manufactured by subcontractor Applied Composites to SNC's design requirements and recently shipped from its San Diego, California facility, to Louisville, Colorado, wh ere it will be integrated by SNC.

"I am very proud of both Applied Composites and my team," said former NASA space shuttle commander and retired USAF pilot Steve Lindsey, now senior vice president of strategy for SNC's Space Systems business area. "Not only did they complete crucial testing for Shooting Star on an accelerated timeline ahead of Shooting Star's arrival in Louisville, but they innovated an entirely new approach to maintain the safety of both teams throughout the COVID-19 crisis."

Shooting Star will now undergo integration with its subsystems before being delivered to NASA's Plum Brook Station in Cleveland, Ohio for testing to ensure it can withstand both launch and space environments.

Dream Chaser is under contract with NASA for at least six cargo resupply and return service missions to the International Space Station under the Commercial Resupply Services 2 (CRS-2) contract. The Dream Chaser and attached Shooting Star transport vehicle can carry up to 12,000 pounds of supplies and other cargo, and returns delicate science to Earth with a gentle runway landing. Shooting Star also allows disposal services for the space station, and for these disposal missions, separates from Dream Chaser and disintegrates upon re-entry into Earth's atmosphere.

Sierra Nevada Corporation's (SNC) Dream Chaser pressure test article arrived at NASA's Kennedy Space Center in Florida on June 3, 2020, from Louisville, Colorado, and was transported to the high bay in the Space Station Processing Facility.

The test article is similar to the actual pressurized cabin being used in the Dream Chaser spaceplane for Commercial Resupply Services-2 (CRS-2) missions. NASA selected Dream Chaser to provide cargo delivery, return and disposal service for the International Space Station under the CRS-2 contract.

Under the contract, Dream Chaser will provide a minimum of six cargo missions to and from the space station, carrying critical supplies like food, water and science experiments, and return to Earth with a landing at Kennedy's Launch and Landing Facility, managed by Space Florida.

The pressure test article was used to validate that Dream Chaser can withstand the demands associated with repeated launches and returns from space. SNC designed the Dream Chaser spacecraft to be reusable for as many as 15 missions. The pressure article specifically verified the composite and bonded structure of the spacecraft.

The test article will remain at Kennedy while SNC engineers use it to develop and verify refurbishment operations that will be used on Dream Chaser between flights.
