Pintle Injector
India's first privately developed pintle injection mechanism
A pintle meters both propellants with one moving element, which is what makes an engine deep-throttleable and restartable — the two properties a reusable booster cannot do without. Abyom's first pintle was designed here, taken through cold flow and spray characterisation to hot fire, and is now the injector architecture for the whole engine family.

Engine Control System
Hardware and software for engine test and control
Every number an engine programme produces comes through its control and acquisition system, so that system decides whether the results can be trusted. This one was built from nothing: a headless acquisition core, operator screens for sequencing and monitoring, read-only observer access, live computed performance channels, and a report generated automatically at the end of every test.

10 kN Reusable Cryogenic Engine
Pressure-fed LNG/LOX, regeneratively cooled, throttleable, restartable
The proof-of-concept engine for the reusable roadmap: fully cryogenic methane and oxygen, pintle-injected, torch-ignited, regeneratively cooled, throttleable, and designed to restart in flight. Design point, sizing and cooling architecture set here, with a generated design workbook and a theory manual so every number carries its derivation, validity range and error band.

Torch Ignition System
Re-ignitable spark torch igniter and its control chain
Reusability means relighting. The torch igniter runs on the same propellants as the engine and has to deliver a stable light repeatedly, on command, with the control chain defaulting to safe on any failure. Two competing architectures were designed in full and taken to a head-to-head down-select.

Reusable Vehicle Development
Hop demonstrators and the launch-vehicle roadmap
The engines exist to fly something. Concept of operations and system requirements baselined for the low-altitude hop demonstrator, with the systems engineering management plan, master schedule, work breakdown and responsibility assignment behind them, plus guidance-navigation-control architecture studies and an autonomous landing-legs concept.

Fundraising & Commercial Strategy
The technical case, in the language investors read
A deep-tech raise is won or lost on whether the technical story and the financial story are the same story. Built the ten-year model, the scenario and valuation analysis, the due-diligence assessment and the investor answer set for an active $3M round, in both INR and USD — after helping close a ₹6 crore pre-seed.
