ULA Unveils Next Generation Launch System with a Little Showmanship

'Behold Vulcan': Next-Generation Rocket Unveiled by United Launch Alliance

United Launch Alliance, the U.S. company behind the Atlas and Delta family of rockets, has unveiled Vulcan, its next generation launch system.
The new Vulcan rocket, which got its name through a poll that attracted more than a million votes, incorporates new engines, a reuse approach that features a mid-air recovery and a new upper stage aimed at enabling complex on-orbit operations.
"[Vulcan is] going to take the best parts of Delta and Atlas and combine them with new and advanced technology to provide a rocket that is not just as reliable and certain as Atlas has been, but also much more powerful, with higher performance, greater flexibility and [is] significantly more affordable," Tory Bruno, United Launch Alliance CEO, said in a press conference held Monday (April 13) at the Space Symposium in Colorado.
In March, the United Launch Alliance (ULA) announced that it plans to phase out use of all but the heavy-lift version of its Delta rocket by 2018. The Vulcan is ultimately intended to replace both the Delta and Atlas, initially as a medium-class launch vehicle to fly in 2019, and then in a heavy-lift configuration by 2024.
...
Step 1, first stage
"The first step is this much more powerful booster," Bruno described. "It will sit atop a pair of advanced technology Blue Origin BE-4 rocket engines. They will burn clean and inherently reusable liquid oxygen and methane fuel."
Last year, ULA announced that it had partnered with Blue Origin, the privately-funded aerospace company owned by Amazon.com founder Jeff Bezos, to create a replacement for the RD-180 engines that power the Atlas today. Under pressure by Congress to phase out all use of the Russian-made RD-180s, ULA selected the BE-4 for the Vulcan.
"They will replace the venerable RD-180s, which generate 930,000 pounds of thrust. This pair of BE-4s will kick that up to well over 1.1 million pounds of thrust, a significant improvement in performance," Bruno said.
"They will sit underneath a stretched set of tanks that will contain significantly more propellant so that we can take advantage of the increased power to provide more impulse as we go to space," he added.
The new booster will also increase the number of possible side-mounted solid rocket motors by one more than Atlas, for a total of six, providing up to 20 percent more power.
...
Step 2, second stage
"We are going to take a giant leap forward in our upper stage," Bruno said. "Burning liquid oxygen and hydrogen, it'll start with these very large high-capacity balloon tanks [that are] so thin, so lightweight, that on Earth they cannot even support their own mass. They would collapse without propellant or pressure to hold their shape. They are truly designed to fly in space."
The ACES will be powered by one to four rocket engines, which Bruno said will be chosen from the existing Aerojet Rocketdyne RL-10 that is used with the Centaur, the Blue Origin's BE-3, or a new engine based on technology being developed by XCOR Aerospace.
The ACES will also incorporate a new integrated vehicle fluids system.
"This is the ultimate in reuse," Bruno explained. "The thing that limits the performance of the upper stage systems in launch vehicles is time — time in space. Eventually our propellants boil off and we're out of usable propellant. This system changes all of that."
Using an advanced internal combustion engine developed by race car manufacturer Roush, the waste propellants will be recycled to re-pressurize the stage's tanks, to generate electrical power and to provide control and attitude thrust.
"This completely changes everything," stated Bruno. "This provides a tremendous extension to our ability to operate on orbit."
"We're going to go from hours to weeks with this system," he continued. "We can take multiple satellites into orbit, we can put them in different planes and when we are done with that we can fly back to space station for operations."
...
Steps 3 and 4: reuse and many uses
The third step of ULA's development plan is to introduce reusability. Instead of recovering the entire first stage, like its competitor SpaceX has been attempting to do using an ocean-based landing platform, ULA's "Sensible, Modular, Autonomous Return Technology," or SMART, initiative will seek to recover only the first stage engines.
"In this approach, when the booster is done and you are finished with the rocket engines, we will cut them off, we will return them to the Earth using an advanced inflatable hypersonic heat shield and then with a very low, simplified logistics footprint, we'll recover them in mid-air and return them to the factory to quickly recertify them and then plop them under the next booster to fly," Bruno described.
"This will take up to 90 percent of the propulsion cost out of the booster," he stated, adding that SMART is only the beginning of the company's plans for how to reuse other components of its launch system, with more details to be announced later. [The World's Tallest Rockets: How They Stack Up]
Finally, combining the three earlier steps, Bruno said the Vulcan rocket would be in position to offer distributed lift, enabling the launch of multiple spacecraft components on multiple launches that could then meet up in orbit by using the new ACES upper stage.
"Now this is the real game changer," he stated. "We could take on our first launch big fuel tanks, supplies, food [and] water, if it is manned mission. Then on the next flight, we bring up the spacecraft, the astronauts in their capsule, and with this advanced upper stage that can fly around for weeks, we can put these pieces together."
"We can go out and tap the resources that are in space," Bruno remarked. "We can asteroid mine and then build the infrastructure for a real and permanent human presence."

Bruno said the cost per launch would be under $100 million without giving specifics including the development costs which ULA says will come from their current profits. But should the government choose to invest the system, they wouldn't be opposed.
It's clear Bruno is trying to respond to the SpaceX threat and is playing catch up. Having finally seen the SpaceX threat for what it is, real as opposed to hype, it was either step-up and compete or eventually lose their lucrative military launch contracts to SpaceX.

It's probably too soon make a judgement in all but one thing, competition is good.

Would be cost competing with Space X but are they targeting Man rating at all is not indicated for what is basically a clean slate design.

ACES? As in, the Lunar architecture program? Good, good.

GW Johnson · 2015-04-15 16:17:22

BTW, the "new engine from XCOR" mentioned in some news releases for ACES is not turbo-pumped! It is LH2-LOX, yes, but it is piston-pumped with their proprietary heat engine, run off rocket engine waste heat!

This is actually a more reliable pumping technology with some years' demonstration behind it in small sizes, and in real manned rocket-powered airplanes. So far, their tests are running great at about 1/10 the thrust needed for ACES application. It is unique to XCOR so far.

Like all projects these days United Launch Alliance's debut Vulcan mission slips to 2023 -CEO

Atlas replacement due to Russian engine use but with development delays with the rocket's engines that are being built by Amazon.com billionaire Jeff Bezos' space company, Blue Origin.

Vulcan, priced at roughly $110 million per launch, already has some 80 contracted missions lined up. It will compete with SpaceX's Falcon 9, priced roughly $62 million per launch, and Blue Origin's forthcoming New Glenn rocket, which uses the same engines as Vulcan.

Seems any further delay may mean cancellation of those future contracts...

Looks like the 2-SRB Vulcan/Centaur flight went off just about as planned. I can find nothing on-line to indicate the future upgrade to recoverable and reusable BE-4 engines has actually been funded. Right now, the thing is all-expendable. It will stay expendable until the engine recovery thing gets funded and developed.

Latest news stories indicate the Peregrine lunar lander is in "deep kimchee": loss of attitude control leading to loss of electricity, and a loss of propellant. Nobody has given up on it yet, so far as I can tell, but it does NOT look good, to say the least. It's in a highly elliptical orbit about the Earth, where the Vulcan/Centaur put it.

GW

update 1-11-24: latest reports seem to indicate it won't go to the moon, much less land. Too much propellant lost.

Vulcan rocket's debut brings long-awaited challenge to SpaceX dominance

Vulcan's launch debut lets ULA start fulfilling a multibillion dollar backlog of some 70 missions, roughly split between government and commercial missions. Amazon's Kuiper satellite project occupies a majority of its commercial bookings.
The starting price for a Vulcan launch is roughly $110 million, half that of its predecessor Atlas V, which anchored ULA's dominance for U.S. national security satellite launches since ULA's 2006 formation. SpaceX's reusable Falcon 9 is pegged at roughly $62 million per launch, but sometimes more for Pentagon missions.
ULA and SpaceX vie head to head for national security missions. The Pentagon in 2020 picked ULA to launch 60% of its national security missions through 2027 and SpaceX to launch the rest. The Pentagon's next launch procurement will pick three core launchers, giving SpaceX and ULA a greater challenge.
Vulcan can use up to six solid rocket motors for extra boost, allowing it to loft up to 60,000 pounds (27,000 kg) of satellites in a low orbit, or 32,000 pounds (14,500 kg) to further orbits. SpaceX's Falcon 9 and Falcon Heavy - three Falcon boosters strapped together - can put up to 140,000 pounds (63,500 kg) to low Earth orbit, or 58,860 pounds (26,700 kg) to further orbits.
ULA used the Russian-made RD-180 engines for its workhorse Atlas V, and that became a security concern in 2014 after Russia invaded Crimea. That, and the rise of SpaceX's cheaper Falcon 9, prompted Vulcan's development.
Atlas V has 17 more booked missions left before retiring. ULA had bulk-ordered its RD-180 engines before American-Russian relations collapsed following Russia's large-scale February 2022 invasion of Ukraine.
Jeff Bezos' space firm Blue Origin has effectively replaced Russia's RD-180, now supplying Vulcan's twin BE-4 engines, which roared to life on Monday and marked Blue Origin's first step into Earth's orbit. Blue Origin is building its own launcher - New Glenn - a more powerful rival to Vulcan that uses 7 BE-4 engines.
ULA plans to increase production to 25 booster rockets annually by late 2025, Bruno said. And it has roughly 100 engineers designing future upgrades to cut production costs.
Those upgrades include a plan to recover and reuse Vulcan's BE-4 engines - about 65 percent of the booster cost - using a heat shield, parachutes and a helicopter to catch them out of the air. Smaller launcher Rocket Lab has adopted a similar strategy.
Bruno said Vulcan upgrades will begin in 2025, and occur every two to three years after that. ULA will test and implement its reuse strategy for Vulcan in the midst of its Amazon Kuiper missions.
