Vyoamyug Aerospace just filed a foundational patent — and it changes how we think about rocket engines.

The invention: An Adaptive Methane-Based Rocket Engine with Helical Micro-Channel Regenerative Cooling and Real-Time Combustion Instability Suppression.

In simple terms — an engine that detects dangerous pressure and temperature instability inside the combustion chamber and corrects itself in under 50 milliseconds. Automatically. During flight.

Here is how it works:

01. Adaptive Multi-Port Swirl Injector
Methane and LOX are injected through independently actuated valves with swirl vanes at 25 to 45 degrees. The mixture ratio adjusts dynamically mid-combustion — something no fixed injector can do.

02. Helical Micro-Channel Regenerative Cooling
Spiral micro-channels of 1 to 3 mm drilled into the chamber walls carry cryogenic methane as coolant before it enters the engine. This eliminates a separate cooling system, reduces mass, and preheats the propellant — all at once.

03. Real-Time Stabilization Loop
Pressure and temperature sensors feed a control algorithm that actuates the injector valves in under 50 milliseconds — adjusting flow, swirl intensity, and mixture ratio simultaneously.

Why methane? High specific impulse. Reusability-ready. Mars-compatible. Our Yuga-1 and Yuga-RX platforms are built around this propellant from the ground up.

Space is not conquered by larger engines. It is conquered by systems intelligent enough to survive the conditions they create.

This is just the beginning.

Indian Govt to fund startup aiming to build Methane-LOX rocket engine

Indian Govt to fund startup aiming to build Methane-LOX rocket engine

Indian Government agency IN-SPACE announced that it has selected three Indian space startups: Astrobase Space Technologies, SatSure Analytics India and TM2SPACE Technologies, as the first set of entities that would receive funding under its Technology Adoption Fund (TAF) Scheme. The TAF is designed to support Indian industry in absorbing, adapting, and commercialising advanced space technologies, thereby bridging the gap between research and operational deployment.

Among the three firms, Bengaluru-based startup Astrobase Space Technologies is the one with the most ambitious goal, they aim to develop a high-thrust Closed-Cycle Liquid Rocket Engine (delivering 80-ton thrust) for space launch vehicles. The startup aims to develop an 80ton-class reusable Methane-Liquid Oxygen(Methane-LOX) rocket engine with high efficiency, which could potentially serve as a commercial propulsion solution for next-generation rockets.

For context, space agency ISRO's most powerful and mainstay operational rocket engine, the Indo-French Vikas engine also delivers about 80-tons of thrust. While the 1970-era Vikas engine is propelled by a toxic combination of Unsymmetric Dimethyl Hydrazine(UDMH) and Nitrogen Tetroxide, the engine being developed by Astrobase is meant to be propelled by relatively clean fuels Methane and Liquid oxygen. The Methane-LoX combination is what powers the SpaceX Raptor engine, which delivers over 280tons of thrust. Indian space agency ISRO is also working on a Methane-Lox engine producing 110-tons of thrust.

IN-SPACE would also be funding Bengaluru-based space analytics company SatSure Analytics India, which is developing Dhaarini, a Large Earth Observation Model (LOM) designed to serve as India's foundational AI platform for remote sensing applications. Trained on diverse satellite and aerial datasets, the model is meant to generate actionable insights across agriculture, infrastructure, and disaster management, enabling data-driven decision-making at a national scale.
Hyderabad-based TM2SPACE Technologies will receive Government funding to develop an indigenous AI-powered star tracker system for satellites, enabling the pointing accuracy required for high-resolution imaging and communication missions. The project will develop StarSense Lite for CubeSats and StarSense Pro for satellites above 50 kg, delivering high-precision attitude determination through advanced optics, electronics, and onboard algorithms.
While the quantum of funding and the timeline for technology development have not been revealed, IN-SPACE said that these three firms were chosen based on a multi-stage evaluation process conducted by an expert committee comprising members from ISRO, the Department for Promotion of Industry and Internal Trade (DPIIT), the Department of Science and Technology (DST), industry, academia. IN-SPACE said it will provide continued technical guidance, monitoring, and milestone-linked disbursement of funds to ensure successful implementation of the selected projects.

The selection of these projects under the Technology Adoption Fund (TAF) marks a pivotal step in our mission to transform Indian private entities into global space leaders. With this fund, our vision is to bridge the critical gap between early-stage development and commercial success. By offering this financial support, we are empowering the private sector to work on cutting-edge space technologies. These projects are not just innovative concepts; they are practical, market-ready solutions that will increase our footprint in the global space economy," said Dr. Pawan Goenka, Chairman, IN-SPACE.
