Quote
“For good reason, Earth’s Moon has long been stigmatized as the archetype of longshots, so unfortunately for CLPS providers there hadn’t been many commercial technologies developed for this niche market. At AGILE we believe that lunar commerce is the lynchpin that can kickstart a vibrant space economy. We’re so fervent in this belief that AGILE Space Propulsion quite literally launched at the opportunity to make the moon the proving grounds for our deep space engines.” -Julian Miller, AGILE CEO

“Satellites and other spacecraft are getting smaller, yet high-performance in-space propulsion hasn’t. It’s why at AGILE, we are pushing the resolution limits of additive manufacturing to make the thrusters that moonshot providers need on responsive timelines. The AGILE team is driven to help put robotic landers on the lunar surface in order to facilitate the foundational science that is needed to safely and sustainably begin bringing humanity back to the moon.” -Daudi Barnes, AGILE Founder & CTO

#A110 back on the stand! This test resulted in a 27.5 second burn within our Sunshine Test Stand vacuum chamber; all things nominal, burn went well.

Never heard of M20 propellant before. Its a mixture of 20% CH6N2 (mono methyl hydrazine or MMH) and 80% N2H4 (Hydrazine). MON3 is 3% NO2 (nitric oxide) and 97% N2O4 (dinitrogen tetroxide).

Sierra Space and Agile Space successfully collaborate on the largest ever in-space bi-prop hydrazine engine.
BLOG
Nov 14

Agile Space Industries has designed, developed, manufactured, tested, and delivered the experimental AX19 preburner for Sierra Space in 19 weeks.

Durango, Colorado (11/14/2023) – Agile Space Industries – Sierra Space contracted with Agile Space to design, develop, manufacture, and test a hydrazine-rich preburner for their VRM5500-H engine. This was done on a timeline of only 19 weeks and it is likely that this is the first time a hydrazine-rich preburner has been developed or used in an engine, at least as far as the public record is concerned. The first prototype unit that was produced demonstrated stable operation across a 6:1 throttle range with high combustion efficiency. This is yet another example of Agile Space successfully developing new technology in record time.

Why was it developed?

Large, high efficiency rocket engines used on large spacecraft need a power source to drive the pumps that take the low-pressure propellants in the tanks to the high pressures needed to run the engine. The AX19 preburner facilitates this by combining all the engine’s hydrazine fuel with some of the engine’s MON-3 oxidizer to decompose the hydrazine into (mostly) hydrogen, ammonia, nitrogen, and water. This hot gas is used as the power to drive the engine’s high-pressure pumps.

Achieving high-efficiency combustion in a rocket engine requires a very efficient injector. There are several different methods for achieving this, but in general having one or both propellants injected as a gas instead of as a liquid will greatly improve mixing and create a higher performing engine. The AX19 preburner enables this capability for hydrazine by converting it into the gaseous products mentioned above.

How does it work?

Hydrazine is a monopropellant, which means that it doesn’t need any oxidizer to combust. This presents a challenge when attempting to design a fuel-rich preburner because partial combustion of the fuel as in a kerosene, methane, or hydrogen engine isn’t possible. Monopropellant combustion is typically difficult to keep stable without running it through a large amount of specialized catalyst, which is both very expensive and difficult to acquire in large quantities.

The AX19 was designed to use as little catalyst as possible while maintaining stable combustion. First, a small fraction of the hydrazine is sent to a catalyst reactor where it is decomposed and sent to the preburner main combustion chamber as a hot mix of ammonia, nitrogen, and hydrogen. Next the remaining liquid hydrazine, which is most of the fuel flow to the preburner, is injected as a liquid into the preburner combustion chamber. At the same time in the main combustion chamber a small amount of oxidizer is injected into the chamber, where it is fully combusted with a portion of the liquid hydrazine and decomposed gas. All the heat added to the chamber from both the reactor exhaust gas and oxidizer combustion is used for rapid thermal decomposition of the remaining, now thoroughly atomized, liquid hydrazine.

Does it work?

The AX19 preburner was successfully tested as a standalone component in October of 2022 in Durango, Colorado on Agile’s Animas test stand. After initial runs it was delivered to Sierra Space for further testing and was operated successfully both standalone and coupled to their full VRM-5500H engine in Q1 and Q2 of 2023. This testing covered the entire throttle range and verified stable operation of the preburner and successful operation of the VRM5500-H engine.

Deep Space transportation, here we come!
BLOG

Nov 20

Agile Space sells their first LE144 thruster adding a new space destination to their list of missions they are providing propulsion for.

We’re excited to announce our first commercial sale of the LE144 bipropellant thruster for a deep space transportation vehicle! While we have already sold over 90 thrusters for commercial LEO and lunar lander applications, this new vehicle class represents a new opportunity with beyond-LEO transportation and servicing vehicles.

“This agreement opens new markets for us, with both commercial and government customers looking for a high performance and proven propulsion solution for transporting and servicing spacecraft beyond LEO,” said Will Francis, Chief Commercial Officer. “We’re pleased to have our propulsion system on-board this first-of-its-kind vehicle, especially given the significance of their mission.”

Our LE144 is a dual-mode engine operating on hydrazine and MON3 provides class-leading performance in chemical in-space propulsion. In addition, it has an innovative regeneratively cooled combustion chamber architecture which enables the system to be nearly undetectable by thermal imaging, which can make it advantageous for national security, rendezvous and proximity, and SDA/SSA missions. The thruster has been hot-fire tested in both modes across various operating conditions. The demonstration in monopropellant mode further expands the scope of this thruster beyond competing products in the same thrust class.

The new customer’s vehicle requires fast orbital maneuverability and our efficient, powerful chemical rocket propulsion solution fits the bill. Additionally, they applaud our additive manufacturing facilities and fully integrated and iterative hot-fire testing program saying, “Agile’s nimble and flexible manufacturing approach coupled with past performance with lunar missions gives us the confidence we need to push the boundaries of delivering services in deep space.”
