ATD Aerospace RS designs, builds and test-fires liquid rocket engines — with technology publicly featured by the European Space Agency under the Future Launchers Preparatory Programme (FLPP).
About us
ATD Aerospace RS is a company specialized in research, design and development across avionics, propulsion and aerospace systems. Our work spans both ESA-funded programmes and projects developed from our own resources, with a focus on applicable, rigorous and testable solutions.
From concept and design through to integration, testing and experimental demonstration — solutions built to be verified, not just proposed.
Every engine, vehicle and subsystem is carried in-house, from the first numerical model to live firing, so performance is proven against real test data at each step rather than on paper alone.
Design, simulation, manufacturing and test under one roof let us de-risk new technology quickly and move from idea to working demonstrator with confidence.
ESA Recognition
Our water-cooled, throttleable 10 kN liquid rocket engine was publicly featured by ESA under the Future Launchers Preparatory Programme (FLPP), demonstrating 100%→60% throttling. ATD is an active ESA partner across the FLPP and GSTP programmes.

Test & Flight Heritage
Real hardware, real test fires, real launches — not simulations alone.
Capabilities
Solid, hybrid and liquid rocket engines — hypergolic storable and next-gen LOX/methane — tested in-house.
Proprietary guidance, navigation and control plus autopilots, backed by in-house 6-DOF guidance and CFD.
Rocket-assisted munitions, guided UAVs and precision mortar rounds, designed and tested for the field.
Reliable data and command links for high-speed, high-altitude missions.
Solid Propulsion & Munitions
In-house solid rocket motors and guided/unguided munitions, developed and test-fired by our team.
Thrust 23,000 N · burn time 1.7 s · dual-base propellant.
Thrust 8,000 N · burn time 7 s · composite propellant.
Spin-stabilized projectile with extended operational range.
Stand and range firings; range depends on configuration.
Plus a solid booster within the ESA portfolio.
High-Altitude UAV
Composite flying-wing UAVs developed in support of European Space Agency demonstrators, reaching near-space altitudes with long-endurance glide range.
Engineering & Simulation
Every engine and vehicle is de-risked with in-house numerical modelling: 3-DOF and 6-DOF trajectory simulation, Monte-Carlo dispersion, internal-ballistic models for solid, hybrid and liquid motors, CFD and thermochemical analysis — even aerobraking and aerocapture studies for Earth and Mars.
Proprietary GNC and autopilot heritage developed since 2006.
Active partner across the FLPP and GSTP programmes.
Romanian Space Agency — national space programme coordinator.
