🚀 The TCA is made up of 3 main parts: the main injector, combustion chamber, and skirt. The main injector converts chemical energy in the propellants into thermal energy through combustion. The combustion chamber and skirt then turn this thermal energy into kinetic energy, propelling the rocket forward.

Relativity Space2 years ago

🛠️ What sets the Aeon R TCA apart? The innovative use of additive technologies. We leverage wire arc additive manufacturing (WAAM) and other methods to 3D print components.

Relativity Space2 years ago

⏱️ With additive technology, we can go from design to testing in just 3 months, allowing rapid iterations and improvements.

Relativity Space2 years ago

💡 We’ve done 14 design-print-test iterations of the main injector, boosting performance and reliability—impossible with traditional manufacturing.

🖨️ Powder bed fusion printing simplifies production, reducing thousands of parts into single pieces printed in days, cutting costs significantly.

Relativity Space2 years ago

🌬️ Additive manufacturing enables intricate cooling geometries and fluid passages, creating unique designs that meet performance and durability goals.

Relativity Space2 years ago

🔧 Using NASA's GrCop-42 alloy and high-strength nickel, we optimize the main combustion chamber's thermal and structural properties.

Relativity Space2 years ago

🌡️ The Aeon R engine withstands temperatures over 6,500°F, more than half the surface temperature of the sun and about 10 times what you'd see in a typical household oven, any metals are typically going to melt at these temperatures. Enter: Regenerative cooling.

Relativity Space2 years ago

💦 Regenerative cooling channels fuel through the combustion chamber walls, pulling heat away and recycling it for combustion—a win for efficiency!

Relativity Space2 years ago

🧑‍🔬 Leveraging testing @NASAStennis E1 test stand we're able to test the thrust chamber and the injector independently of the rest of the engine in parallel with the turbo machinery development.

🌌 Join the team - we're not just making rockets; we're pioneering technologies that could become industry standards.

Terran R build is continuing to ramp up this fall. From avionic builds to expanding of our machine shop capabilities and more. 🔥In prop, teams completed assembly of the second Aeon R engine for first flight and reduced average cycle times across key engine components by 50%. 💻The avionics team is building the flight hub box, which will serve as Terran R’s central node for routing data and distributing power to critical systems. 🚀Welding of the first stage tank is progressing with 3 circumferential friction stir welds now complete.

10 successful ignitions. 790 seconds of cumulative hot-fire time for the ARCOS Thrust Module. Our latest ARCOS TCA hot-fire campaign at the German Aerospace Center DLR - English marks a major milestone in the development of our in-house methalox thrust chamber assembly. The campaign demonstrated stable and repeatable operation across a wide operating envelope (60–105% thrust and multiple mixture ratios), validating a deeply throttleable core thrust module to be replicated across ARCOS’ aerospike architecture. Reliable ignition and shutdown, stable chamber pressure behaviour, and no critical structural damage were observed after testing. A key step forward towards full ARCOS aerospike engine assembly — and for Europe’s propulsion capabilities. A huge thank you to our team for always pushing the limits and overcoming every challenge along the way; and to German Aerospace Center (DLR) team for their continuous support and collaboration. #PoweringSpace

What’s hotter than a Texas summer? Our Miranda engine.🔥 We fired our Miranda engine at full power for 226 seconds— that’s almost 4 minutes! This endurance test verifies that the engine can perform beyond the nominal flight duration, meaning this engine is one step closer to being ready for flight. Seven of these Miranda engines will generate the thrust needed to lift our Eclipse rocket off the launch pad and propel it into orbit.

LEAP 71, a Dubai-based AI engineering company announced today the successful test firing of a liquid rocket engine created entirely through Noyron, the company’s Large Computational Engineering Model. The engine was designed autonomously without human intervention and then 3D-printed in copper. The engine with 5 kN (500 kg / 1124 lbf) of thrust, generated the expected 20,000 horsepower, and completed all tests, including a long duration burn.

This is the most powerful commercial jet engine currently flying on an operational airliner. The GE90-115B was built by GE Aerospace specifically for the Boeing 777-300ER. It weighs around 8.3 tonnes, has a 3.25 metre wide fan and produces up to 512 kN (115,000 lbf) of thrust from a single engine. To understand the sheer scale of that output, it produces roughly 2.7 times the thrust of the F135 jet engine powering the F-35, the most powerful fighter engine currently in service. The enormous fan at the front uses just 22 carbon fibre composite blades with titanium leading edges. At maximum thrust, it pulls in roughly 1.4 tonnes of air every second, with nearly 90% bypassing the core rather than passing through the combustor. At around 150 knots during takeoff, its 512 kn of thrust corresponds to roughly 39.5 MW of propulsive power, or in automotive terms around 53,000 hp from one engine. And it burns roughly 4-5 kg of jet fuel every second at maximum power conditions. Two of these engines are enough to power a fully loaded 777-300ER weighing more than 350 tonnes. Even if one engine fails after the critical point during takeoff, the aircraft is certified to continue the takeoff and climb on the remaining one GE90 engine. Each engine costs around $35-40 million. More than 2,500, GE90s engines have been built, and the GE90 family has accumulated nearly 130 million flight hours. And this is precisely why companies like GE Aerospace remain so difficult to displace in jet engines. There is never one breakthrough. GE spent roughly $2+ billion developing the GE90, chasing small gains across hundreds of systems, efficiency, materials, reliability and component life.
