РН Electron от новозеландской Rocket Lab

[Василий Ратников]

Electron's manifest is booked for the next two years for dedicated flights. Little bit of space for rideshare available, but we're not seeing a slowdown in demand any time soon.

На два года уже все выкуплено, и РокетЛаб не ожидает падения спроса на запуски мусоросатов.

PS такими темпами патриотам надо будет переходить на подсчет выведенных тонн на орбиту, а не на количество запусков, а то стремно будет быть после США, Китая и Новой Зеландии.

актуальный вопрос
There are a lot of fears floating around that the overwhelming amount of debris in space will continue to grow and make future space launches next to impossible. Has Rocket Lab looked in to the space debris situation, and, if so, do you have any ideas on how to deal with it?
как там с мусором

ответ
This has been a big consideration for us and has driven a lot of design. This is the reason for the Curie kick stage. We put the second stage into an elliptical transfer orbit intentionally so that it deorbits really quickly. Then finish the orbit with the kick stage which has the ability to deorbit itself. Also, most of our LEO payloads deorbit within 5-7 years max.

Для начала они сводят с орбиты вторую ступень
А потом низко орбитальные мусоросаты долго не живут.
Так что я делаю выводы, что РокетЛаб не видит проблемы в мусоре на НОО.

Луна
вопрос
Question about Moon Express mission(s): Would the electron be in a 2 stage or 3 stage configuration? What is the maximum weight it could send to the moon?

Ответ
Would be a two stage for lunar mission but would have big ass propulsion on the spacecraft.

ступени понятно 2, никто не будет делать 3 ступень для такого редкого кейса,
Луны планируют достигать топливом в космическом аппарате.

Судя по выводимым массам ))) я думаю 90% массы Moon Express будет топливо ?

[Василий Ратников]

Хороший вопрос
Do you wish to comment on any plans on developing new technologies and/or new launch vehicles after Electron "freezes" like the Block 5 Falcon 9? Or will Electron be continuously evolving?

Ответ.
Our goal from the outset was always to produce one vehicle very well that could be produced on a mass scale. It's the only way to achieve the launch frequency the market needs. We're pumping out around one Electron a month at the moment. There will always be continual innovation in all areas of Rocket Lab.

Они стремятся выйти на массовое производство. Сейчас их темп 1 Электрон в месяц.
Постоянного внесения изменений в конструкцию они не планируют.
При этом понятно НИОКР будет идти дальше.

от себя - видимо имелось ввиду что только после накопления критической массы изменений, будет запускаться новая модель на конвейер.

Актуальнейший вопрос современности
где же строить космодром
I'd like to ask what the reasons were for choosing New Zealand as a launch site (picturesque as it is) over another, more northerly site such as another Pacific island, Australia, Indonesia, PNG, etc

Очевидный ответ.
Launch Complex 1 gives us the widest range of launch azimuths of any established site in the world. Best to launch from a small island nation in the middle of the ocean with minimal sea and air traffic, and no land to fly over.

но дуракам закон не писан.

Но ведь 3-я - апогейная - ступень уже есть и была использована во 2-м запуске "Электрона".

We ended up with linerness tanks with common bulkheads that have similar oxygen compatibility to aluminium but much lighter mass.

Вот это в реальности - самое интересное во всей конструкции "Электрона".

Не понимаю что такое положительный входящий поток денег ? Это у них есть оплаченные заказы на 5 запусков ?

После пяти запусков - они выйдут в плюс по деньгам. Т.е. получат больше чем потратили. 
Хотя это скорей не относится к погашению кредитов за оборудование.

Означает ли нагнетание топлива при помощи ЭД возможность глубокого дросселирования тяги?

октоген пишет: 
Да, но снизу тяга будет ограничена нормальным охлаждением КС. Так что дросселировать как водородники все равно не получится.

И каков нижний порог? процентов 40 будет ?

Rocket Lab confirms three launches with Spaceflight, including missions for Canon Electronics and BlackSky

Rocket Lab confirms three launches with Spaceflight, including missions for Canon Electronics and BlackSky

Huntington Beach, California, 11 June 2018:

Rocket Lab, a US orbital launch provider for the small satellite industry, has today announced a partnership with satellite rideshare and mission management provider, Spaceflight, for three orbital launches across 2018/19.

The first mission, scheduled for the end of 2018, will launch a BlackSky microsat along with several rideshare customers. The second launch will be a commercial rideshare mission in early 2019. Rocket Lab and Spaceflight have also signed a letter of agreement, which is expected to be finalized in the next few weeks, for a third mission to fly a Canon spacecraft in late 2019.

The three-launch deal cements Spaceflight's first missions aboard the Electron launch vehicle. The missions join a busy manifest that will see Rocket Lab launch monthly by the end of 2018, scaling to a launch every to weeks in 2019.

"We're thrilled to welcome Spaceflight onto our growing launch manifest," says Rocket Lab founder and Chief Executive, Peter Beck. "Rapid and repeatable access to space is crucial for the development of vital infrastructure on orbit, and Rocket Lab is delivering it now. In partnering with Spaceflight, Rocket Lab is offering the long-underserved SmallSat market streamlined launches that enable innovative missions, like those of Canon Electronics and BlackSky."

One of the Electron missions will loft an Earth observation satellite for Canon Electronics. This spacecraft follows on from Canon Electronics' experimental CE-SAT-I which was launched in 2017.

"This launch is very critical for Canon Electronics as we are launching a satellite built with all components made by Canon Electronics," said Dr. Nobutada Sako, group executive, Satellite Systems Lab, Canon Electronics Inc. "Just as Canon provides world premium technologies, sales, and services, we believe Spaceflight and Rocket Lab offer the same premium services to their clients and look forward to a long-term partnership with them."

Melissa Wuerl, Spaceflight's vice president of business development, says adding the Electron to Spaceflight's portfolio of small launch vehicles fulfils a need for customers to access space with shorter lead times. "We are pleased to offer first-class integration services and dedicated launches for our customers on the Electron rocket."

All three missions will lift off from the Rocket Lab Launch Complex 1 on the Māhia Peninsula in New Zealand and deploy the spacecraft into Low Earth Orbit. Spaceflight has procured the launch capacity on behalf of its customers and will provide mission campaign integration services. Rocket Lab will assist with satellite to launch vehicle integration and will provide the launch service to orbit using the Electron. All payloads launched by Rocket Lab from New Zealand are subject to approval by the New Zealand Government.

Rocket Lab to expand launch capability with US launch site

Huntington Beach, California. 10 July 2018.

US orbital launch provider Rocket Lab has today confirmed plans to expand its launch capability by developing a US launch site, with four US space ports shortlisted to launch the Electron rocket. Final selection is underway with Cape Canaveral, Wallops Flight Facility, Pacific Spaceport Complex – Alaska and Vandenberg Air Force Base. A decision on the confirmed site, to be named Launch Complex 2, is expected to be made in August 2018.

Спойлер

Designed to serve both commercial and US government missions, the US launch site expands on Rocket Lab's ability to provide customers with the rapid, flexible and cost-effective access to orbit needed to support the increasing number of small satellites.

"The development of Rocket Lab's US launch site strengthens our existing position as the industry leader providing frequent and tailored access to orbit for small satellites. Launching from US soil adds an extra layer of flexibility for our government and commercial customers, offering an unmatched ability to rapidly deploy space-based assets with confidence and precision," said Rocket Lab founder and chief executive Peter Beck.

"We believe the launch process should be simple, seamless and tailored to our customers' missions - from idea to orbit. Every aspect of the Electron orbital launch program is designed with this in mind and Launch Complex 2 is the next step in this strategy."

The four potential launch sites are being assessed against a range of criteria, including anticipated pad construction cost and timeframe, regulatory lead times and ongoing costs once the site is operational. Rocket Lab is considering East and West coast options to explore a wide range of inclinations matched against current and anticipated manifest demand.

[свернуть]

Launch Complex 2 will be designed to support monthly orbital launches. Once the final site is confirmed, construction will begin immediately, with the first mission from Launch Complex 2 slated for Q2 2019. Rocket Lab will construct its own pad infrastructure tailored to the Electron launch vehicle.

The development of Launch Complex 2 will see Rocket Lab continue to expand Electron rocket production at the company's headquarters in Huntington Beach, California, to supply complete launch vehicles for government and commercial customers.

Rocket Lab already has the ability to launch more frequently than any other launch provider thanks to operating the world's only private orbital launch facility, Launch Complex 1, on the Māhia Peninsula in New Zealand. Launch Complex 1 is licensed to launch up to every 72 hours.

А посмотрите на РД-191. +-5% от него предрекаю. Охладитель то керосин, им много не наохлаждаешь.  НО мое утверждение не есть четкое знание в данном случае.

Для РД-191 нашел данные "..[TH]Throttle range[/TH]

27–105%

.."
Что то мне кажется подозрительной цифра в 27%.
Но если она верна,получается по вашему для резерфорда доступен нижний порог в  ~22% ?
